The VaporWorx Fuel Pump Controller

Wiring VaporWorx Fuel Pump Controller

We always say that our Infinitybox system plays nicely with other electrical accessories in your car.  This blog post is another great example of that.  We got a call from a customer asking about wiring the VaporWorx Fuel Pump Controller with his Infinitybox 20-Circuit Kit.  He was worried about having to wire in additional relays and run a lot of wire.  In reality, wiring the VaporWorx Fuel Pump Controller is simple and easy with the Infinitybox system.

The VaporWorx guys make some very cool products.  Click here to get to their website.  You have to appreciate a company with the tagline “We Give You Gas”.  Their core products improve the delivery of fuel in your resto-mod, street rod, hot-rod or Pro-Touring build.  They have been innovating products for reliable fuel delivery in cars with EFI systems since 2009.

Their core products are designed for returnless fuel systems.  There is only one fuel line going from the in-tank pump to your fuel rail.  There is no fuel regulator on the rail and no return line that brings excess fuel back to the tank.  Their Fuel Pump Controller mounts in the rear of the car, near the fuel pump.  It actively monitors the fuel pressure in the line at the outlet of the pump.  Using pulse-width modulation (PWM), they vary the pump power to keep the fuel pressure within a tight window.  This reduces dead-heading of the fuel pump and also reduces the amount that the fuel gets heated.  We use PWM to control things like fan speed and light dimming from our POWERCELLs and have blogged about how that works before.  Click on this link to learn more about PWM.

This blog post is going to walk you through wiring the VaporWorx fuel pump controller with our Infinitybox system.  We are only going to cover the connections from the battery, from the POWERCELL and to ground.  See their manual for more details on the rest of the sensor wiring required for their controller.  You can access the manuals and installation instructions for their products by clicking this link.

Just like any other blog post where we talk about integrating the Infinitybox system with other products, please carefully read and understand all of the steps required to install the VaporWorx Fuel Pump Controller.  You are messing with flammable fuel and electricity.  Make sure you are completely comfortable with doing this job.

For the sake of this blog post, there are three connections that we are going to cover: primary power from the battery, the fuel pump trigger from the POWERCELL and the grounds.

The primary power for the fuel pump controller is going to come directly from the battery.  This should be a simple connection since the controller should be mounted close to the pump in the tank and most guys are relocating their batteries to their trunks.  Follow the recommendations from VaporWorx for the gauge of wire going from the positive terminal on the battery to the BAT+ terminal on their module.  It is very important that this gauge of wire is sized correctly and that it is fused as close to the battery as possible.

Next, the fuel pump controller and the fuel pump need to be grounded.  The VaporWorx team recommends that you ground their pump controller and the fuel pump directly to the negative terminal of the battery.  This should be easy in most installs since guys are relocating the batteries to their trunks.

Last, the VaporWorx controller needs a fuel pump enable signal from the ECU.  When wired with the Infinitybox system, this signal is going to come from the fuel pump output on your rear POWERCELL.  In most 20-Circuit Kits, this is the TAN wire on the rear POWERCELL but check your configuration sheet for details on this output.  The POWERCELL output is going to connect to the blue wire in the GT150 connector.

The advantage of using the POWERCELL to supply the fuel pump enable signal is that you do not need to add any additional wiring.  You already have the POWERCELL located in the rear of your car.  You do not need to run a wire from the front of the car to the back.  You can simply use the POWERCELL to supply this signal.

Once you have power, ground and the fuel pump enable signal wired, you need to wire your EFI system to your Infinitybox MASTERCELL.  This is how the POWERCELL knows when to turn on the output for the fuel pump enable signal.  To do this properly, you need to understand if your EFI system uses a ground trigger for the fuel pump or a positive signal for the fuel pump.  The wiring diagram for your EFI system will define this.  Alternately, we have wiring diagrams for all of the popular EFI systems in the Resources section of our website.

If your EFI system sends a ground trigger for the fuel pump enable signal, you can wire the MASTERCELL fuel pump input to the EFI system’s fuel pump output.  We strongly recommend wiring a diode in series to buffer the MASTERCELL from the ECU.  As an example, the FAST XFI 2.0 sends a ground trigger for the fuel pump enable signal.  You can see how the recommended diode is wired at this link.

If your EFI system sends a positive trigger for the fuel pump enable signal, you need to flip this to a ground trigger.  You can use one of our inVERT Mini Buffers to do this easily.  The Holley Sniper EFI System uses a positive trigger for the fuel pump enable signal.  You can see how to wire in the inVERT Mini at this link.

This wiring diagram shows you all of the connections between our Infinitybox system and the VaporWorx Fuel Pump Controller.  You can download a PDF version of it by clicking this link.

inMOTION Video

We just released a new video that covers the features and benefits of our inMOTION Motor Controller Cell.

Infinitybox inMOTION Motor Controller Cell

inMOTION is a unique module that connects to the CAN network of your 20-Circuit Kit.  It looks like a POWERCELL but acts differently.  Instead of turning 10 things on and off like a POWERCELL, it reverses the polarity to 5 things.  We originally designed inMOTION to control power windows and power lock actuators.  Instead of relying on a switch, inMOTION has special h-bridge relays that reverse the polarity.  This lets you change direction of things like power windows, power locks, linear actuators and valves.

That is just the beginning.  inMOTION is smarter than a POWERCELL which means that you can get express features on your windows with no limit switches.  You can also get wireless control through inLINK or a smart phone attached to inTOUCH NET.

Check out this video for a deeper dive into what inMOTION can do.

POWERCELL

Our 20-Circuit Kit is the core to the electrical system in your car.  It is more than just a wiring harness.  It is a universal wiring system that gets you the most advanced, functional and reliable electrical control on the market.  The 20-Circuit Kit starts with our MASTERCELL, which connects to your switches.  It also includes two of our POWERCELLs, which we call the muscles of your system.  The MASTERCELL sends commands to the POWERCELLs to locally power your lights, ignition, starter solenoid, cooling fans, fuel pumps, horn and other accessories.  We’ve talked about the MASTERCELL in more detail in a recent blog post.  You can link to that here.  This post is going to cover more details about our POWERCELL.

The 20-Circuit Kit includes 2 POWERCELLs.  Each POWERCELL can control 10-outputs.  One POWERCELL is for the front of the car, the second is for the rear of the car.  The front POWERCELL is set up to control your headlights, high-beams, turn signals, front running lights, horn, cooling fan, ignition power, starter solenoid and dash power.  The rear POWERCELL is set up to control your rear running lights, turn signals, brake lights, fuel pump, back-up lights, dome lights and other accessories.

Connecting your loads to the POWERCELL is very easy.  You run the output harness from the POWERCELL to your light, fan, pump or other accessory.  You cut our universal harness to length.  You connect our output wire to the wire on your load.  That’s it.  Click on this link to get more details on connecting your POWERCELL outputs to the electrical loads in your car or truck.

You put the POWERCELLs in the car were you need them.  This lets you eliminate size and weight of the wiring harness in your car.  The installation is simpler because the runs of wire are shorter and troubleshooting is easier.

The POWERCELL is a remote fuse and solid-state relay box.  The fuses that you need to properly protect your wiring harness are built into the POWERCELL.  You do not need to add separate fuses.  Also, the solid-state relays that control your loads are built into the POWERCELL.  Each output can carry up to 25-amps continuously so you do not need to add external relays to control your lights, fans, pumps and other accessories.  Also, we don’t use mechanical relays in our POWERCELLs.  Our outputs are controlled by solid-state MOSFETs.  This are rugged and reliable and give you tons of benefits over traditional relays.  Check out this link to learn about some of the advantages of a MOSFET.

This video walks through more of the details of the Infinitybox POWERCELL.

You can easily add extra POWERCELLs to your 20-Circuit Kit if you need to expand the output capacity beyond 20.  Each additional POWERCELL gives you 10 more outputs to your Infinitybox system.  The POWERCELL kit includes the POWERCELL plus all of the harnessing required to connect to your existing 20-Circuit Kit.  You can learn more about the POWERCELL kit by clicking this link.

MASTERCELL

The MASTERCELL is the brain of our Infinitybox system.  It is the core of our universal 20-Circuit Kit.  It connects to all of the switches in your car and decides what should be turning on and off in your electrical system.  The MASTERCELL connects to the POWERCELLs, inMOTION cells and other Infinitybox accessories through our CAN network and sends commands to control everything in your car.

All of your switches wire to the MASTERCELL.  Examples include you headlight switch, ignition switch, brake pedal switch and turn signal stalk.  You can even connect the MASTERCELL inputs to your ECU directly to take signals to control your cooling fans and fuel pump.  The MASTERCELL inputs work by being grounded to turn the input on.  There is no power at the switch.  Instead of having to bring power to the switch, you simply connect the MASTERCELL input to one terminal of the switch and you ground the other side of the switch.  When the switch is turned on, the MASTERCELL input gets connected to ground.  The MASTERCELL sees this ground signal and sends the commands to turn things on and off on the POWERCELLs.  Check out this blog post for a more detailed description of how the MASTERCELL inputs work.

The MASTERCELL also has the capability to include our optional inLINK radio.  This accessory gets you remote control of your Infinitybox system through a key fob.  You can control your lights, pop your trunk and access our power security and immobilizer features by pushing a button.  The receiver for the inLINK radio gets installed inside the MASTERCELL so there is no separate box that you need to install, wire or conceal.  This link will take you to more details on inLINK.

The MASTERCELL also has our inSIGHT display installed in it.  This LCD screen is your window to the Infinitybox system.  It lets you see what the system is doing and it lets you easily troubleshoot problems if you have them.  This link will take you to our diagnostics and troubleshooting guide to learn more about what you can do with the MASTERCELL inSIGHT screen.

This video will walk you through the details of the MASTERCELL.

Fingernail for 2019 Infinitybox Introductory Video

Infinitybox Introductory Video

Infinitybox is excited to announce a new series of videos going through the details of our Infinitybox system.  We’ve shot them in a very simple and effective way to get the point across.  Jay Harris, the president of Infinitybox, will take you through every piece of our system.  He will also walk you through the process to wire your car with our Infinitybox system.

In this introductory video, Jay describes how our Infinitybox system works and how it is different from traditional wiring harnesses.  Until Infinitybox came onto the scene in 2009, little had changed in the way you wire a car since the Model T.  Our system revolutionized the way restorations, kit cars, resto-mods, street rods, hot rods, race cars and Pro-Touring cars were wired.  Instead of a single, central box of fuses and relays, the Infinitybox gives you separate modules that you put in the car where you need them.  The separate Infinitybox modules are connected with a simple and thin data cable.  You can watch the introductory video here.


This is the first video in the series.  There are more coming that go through each of our specific products.  Be sure to subscribe to our YouTube channel Infinityboxllc and click on the bell icon to get notified when we post new videos.

Custom BMW E9

Here is another great example of what our customers can do.  This car is stunning and we can honestly say that we’ve never seen another like it.  John Ward of Fuel Bespoke Design in Australia just had a great article published in Silodrome magazine.  The article covers the details of his stunning restoration of a 1970 BMW 2800CS lovingly named “Von Trapp”.  The article covers the car in detail and the pictures are awesome.  Andrew Jones shot the pictures and we heartily thank him for their use in this blog post.

John started with a pretty rough car for this project.  It took a ton of body work, straightening and reinforcing to get the car to what you see today.  John wanted to do this car as a true restomod:  keep it original on the exterior and interior but put modern features under it.  For example, he replaced the original powerplant with a modern E46 M3 3.2 litre 330HP S54 motor and the E36 M3 5-speed manual transmission.

Finished Factory Five GTM wired with the Infinitybox System

Showing off inLINK in a Factory Five GTM

We have been working with a customer to finish the details of a Factory Five GTM build.  This car was wired with our 20-Circuit Kit, inMOTION, inRESERVE, inTOUCH NET, inVIRONMENT and inLINK.  Essentially, the car has the works.  It was originally built and wired by Shane Vacek at Vraptor Speed Works.  Izzy Dunn at Dunn Customz just finished the details on the car for the customer.

This video shows a walk around of the finished car.  It turned out great.  You can see the front POWERCELL mounted under the hood.

In this blog post, we want to feature one of the simplest accessories in the Infinitybox lineup.  That is inLINK.  inLINK gets you wireless control of your car or truck from a simple key fob.  You can turn on your lights remotely, pop your doors and trunk, and enable the Infinitybox security system.

Since your Infinitybox system is controlling the ignition, fuel pump and starter, we can easily stop someone from starting the car and driving off with it.   When you press the “lock” button on the inLINK key fob, we disable the ability to turn on the ignition, power the fuel pump and crank the starter.  Even if someone where able to get in the car with inLINK security enabled, the MASTERCELL completely blocks the ability to get the engine running.  The best part is that this is completely integrated into our Infinitybox system.  You do not need to buy a separate security or immobilizer system and integrate it into your wiring harness.

When you’re ready to drive the car, you simply press the “unlock” button on the key fob and you’re ready to go.

The owner of this car wanted door poppers.  They are using POWERCELL outputs to power a solenoid in each door.  They can push a button inside the car to pop these solenoids.  They also have buttons on the outside of the doors that let them pop the doors.  They also wanted to be able to pop the doors from buttons on the key fob.

All of this is very easy with the Infinitybox system.  Our team custom programmed the door popper outputs to pulse for 1 second.  The customer can push buttons on the key fob or use buttons on the door.  Very simple.

Here’s the coolest part of all.  The customer wanted buttons on the outside of the car to be able to pop the doors.  However, the customer does not want those buttons to work when security is enabled.  That is a very simple thing to do with our Infinitybox system.  As part of our custom programming, we set the MASTERCELL inputs to be disabled when security is on.  That way, no one can walk up to the car and open the doors unless they have the inLINK key fobs specifically programmed to that car.  The video below shows how this works.  You can see how security is enabled and disabled.  You can see how the doors can be popped from the inLINK key fobs and you can see how inLINK security disables the exterior switches.

Thanks to Izzy for sharing these pictures and videos.

Example of a door pin switch used to control dome lights and interior lights.

Wiring Door Pin Switches

This blog post is going to cover how to wire your interior and dome lights.  In most cases you want these lights to turn on when you open a door to your car.  We’ll show you the best way to wire your door pin switches and connect your POWERCELL outputs to your dome lights and interior lights.

Example of a door pin switch used to control dome lights and interior lights.

Example of a door pin switch used to control dome lights and interior lights.

Each door in your car has a pin switch.  Sometimes these are called door jamb switches.  They are very simple devices.  They have one terminal on them.  This terminal originally connected to the ground side of your dome light circuit.  The threaded metal part of the switch connected to your cars ground through the metal part of the door jamb.  These switches work backwards from most people would expect.  When the car door is open, the contact on the switch is closed to ground.  If you think about it, that is what you want.  You want the circuit completed when the door is open.  In the original wiring on most cars, you had battery power supplied to one side of your dome light.  The other side of the light was connected to ground through the door pin switch.  When you opened the door, the switch closed.  This completed the circuit to ground so the dome light came on.

The inputs to an Infinitybox MASTERCELL work the same way.  They get activated when they are connected to ground through a switch.  You can learn more about how the MASTERCELL inputs work by clicking this link.

We do not dedicate a POWERCELL output for dome lights or interior lights.  You can use any of the OPEN outputs that are listed on your configuration sheet to do this.  Simply choose an OPEN output on a POWERCELL and connect that to one side of your dome light circuit.  This link will get you more information on using OPEN outputs.  Connect the other side of your dome light circuit to ground.  Check your configuration sheet and get the MASTERCELL input that corresponds to the OPEN POWERCELL output that you picked.  That input is going to connect to your door pin switches.

In most cases, you will want to have your dome lights turn on if any of your car’s doors are opened.  This is the same if you have a 2 or 4-door car.  To do this, you are going to wire the pin switches in each of your doors in parallel.  You are going to take your MASTERCELL input and connect it to each of the terminals on your door pin switches.  You can splice off of the input wire at the MASTERCELL and run separate wires to each switch.  You can also daisy-chain from one switch to the next in the car.  This wiring diagram shows how to connect the MASTERCELL input for your dome lights to the door pin switches.

Simple Infinitybox wiring diagram showing how to wire door pin switches in parallel to control dome lights and interior lights.

If you open one of your doors, the door pin switch will ground the MASTERCELL input.  The MASTERCELL will send a command to the POWERCELL to turn on the output for the dome lights.  If you open a second door, the input will still be grounded because the switches are wired in parallel.  The dome lights will not turn off until you close all of the open doors.

An added bonus of our Infinitybox system is the ability to theater dim your dome lights.  When the doors close, we can set your dome light to slowly fade away over 10 seconds.  Give our technical support team a call to get this feature on your system.

Using Open Outputs

This blog answers a question received from a customer plus shows off the progress on his car.  Mike O just finished his LS3-powered Brunton Stalker Classic.  This is a tribute to the Lotus Super 7You can learn more about there car by clicking this link.  His question was about how to use the open outputs on his Infinitybox 20-Circuit Kit.  He wanted to add a water pump and asked if he could use the any of the open outputs to do this.  He also wanted to know how to wire the MASTERCELL inputs to control his open outputs.  We thought that this was a good question that was worth posting up on the blog.

Before we get too technical, let’s talk about the car.  This is another example of a very unique build and shows how simple yet powerful our Infinitybox system can be.  Mike has been working on this car for a while.  He squeezed a 430 hp GM LS3 engine into this chassis all managed by a custom Speartech engine wiring harness.  Considering that the original Super 7’s came with engines the same size as those used in most garden tractors, this LS will make the Birkin fly.

He handcrafted the rear fenders, back panel, cover and rear diffuser out of aluminum.  He custom made the flared wings out of fiberglass.  On top of all of that, he painted it Lotus Racing Green with a yellow racing stripe.  The LS3 is mated to a T-56 6-speed and the brakes are disc from Wilwood.

 

Mike wired the car with our 20-Circuit Kit and inLINK.  The benefit to him was simplifying the wiring, reducing the total amount of wire and giving the flexibility with making changes over his project.  He mounted his MASTERCELL and front POWERCELL just forward of the dash board.  Here is a picture of him laying these out.

 

 

Okay… now here’s Mike’s question.  He wants to add a Meziere electric water pump to the car.  He originally had a belt-driven water pump.  He wanted to add this electric pump to decrease the load on the engine plus give him more flexibility to cool the car.  Per the manufacturer’s specs, this pump draws 6 to 7-amperes under normal use.  This is well under the 25-amps that a POWERCELL output can supply.

Mike already has the car wired.  With a traditional wiring harness, adding accessories after the fact usually requires running new wires through the car.  With the Infinitybox system, we build in auxiliary outputs that can be used for practically anything.  These outputs can be used for things like extra lighting, multiple fuel pumps, amps, sub woofers and additional cooling fans.  In a typical install, there is 1 open output on the front POWERCELL and 4 on the rear.  Mike simply needs to connect the water pump to the open output on his front POWERCELL.  Then he needs to take the corresponding MASTERCELL input and connect that to a switch for the water pump.  Since he already has the Infinitybox backbone installed in the car, he doesn’t need to run any extra wire through the interior or through the firewall.

The configuration sheet that came with your kit will get you all of the details that you’d need to use these open outputs.  This link will take you to a blog post that gives you more detail on how to read the configuration sheet.  All of the open outputs are set to TRACK.  This means that the output will track the state of the switch.  When the switch is on, the output is on.  When the switch is off, the output is off.  In the case of Mike’s water pump, he can have a switch on the dash what would turn the pump on and off.   He could also wire the MASTERCELL input for his pump directly to the ignition switch so the water pump will turn on when the ignition is on.  You can use this functionality right out of the box with no configuration changes.

We can also custom configure the behavior of these open outputs for you.  One of the most common is to add a timer to the open output used for an electric water pump.  We can set this output to stay on for a period of time after you turn it off.  For example, your electric water pump could continue to run for one minute after the ignition is turned off to help cool down your engine.  Contact our technical support team for more information.

This example shows how flexible and powerful the Infinitybox system can be in your car.  It helped Mike modify the electrical system in his car with minimal changes to add this new water pump.  Thanks to Mike O for asking the question and for sharing the pictures.  The car looks great and we’re proud to be a part of it.
