Vaporworx

[CarlC]

I'm using the CTS-V pump to my instructions don't have an H pin. The fuel pump out from the relay should got to the D terminal through the plug that mates to the blue.
Looking at the instructions on Aeromotive for the 66162(i just picked one) it seems like its for an aftermarket fuel pump, I'm assuming that's what you're using? From what I gather in the the instructions, you would not use the yellow wire because that's for ECM's that have a negative pump trigger. The blue is for ECM with a positive pump trigger signal which the LS has.
The negative wire from your fuel pump would attach to the vaporworx controller where the negative battery terminal connection also goes.

The 66162 is a ReturnX system meant to be used with a return line and external pressure regulator. It is not recommended to use a return-type system with modern fuel modules, including the CTS-V.

Hey Don,

The latest version of the pwm controllers have a negative trigger option as well for turn-on. Not many ECM's use negative, but a crafty person could figure a way to use it to turn the controller on with the engine off ;-)

Oh that is crafty…

Carl, what are the ramifications of using a return-type system with a modern fuel module? In my case, an Edelbrock 35860 Pro-Flo4 and a ZL-1 module?

how do you get a return on a fuel module that only has an outlet?

Sorry, couldn't resist.

The correct answer is you can not add a return to the module. You can add a return to the tank, though. The problem is that it will pump the reservoir dry in the module, which is one of the reasons to run the module in the first place.

When you compare the costs of a vaporworx controller to a quality bypass regulator and the materials needed to run the return line and then factor in the time spent mounting and routing said return line......the vaporworx controller is really a great deal and you get a far better fuel system.

I wonder if this forum will ever get a like button…

I mounted mine on the inner wheel tub. I ran the harness over the edge of the trunk pan and down across the tank using the same hole as the fuel sender wires.

Did you purchase that fuel door somewhere? Someone did a poor job of one on my car that I was going to just leave but I like that one & it looks large enough to cover what I have now.

Alright I got my vaporworx controller all wired in,and have some questions, I talked to Carl and he said I could splice into the green,with white wire which is pin 50 on x1,black connector
On my e38 ecm that controls the fuel pump to come on.
The instructions from my psi harness show fuel pump + #87 relay to positive fuel pump.
Has anyone wire the blue wire to there fuse/relay like that?
And he also said to put the stock pressure regulator which is 80psi and the 60Psi from vaporworx/aeromotive will cause me issues???
And to get a fuel pressure gauge to set the pressure instead.
Oh and ive enclosed pictures of the psi relay diagram.
And would like to know were i can get mounting tabs or plates.to mountvthe fuse box.
And one for the small vaporworx connector.
Or engine is ly6 6.0
The pump in using is a gen5 camaro ss 1le pump.

Carl said to tap into the fpr wire from pin#50 on the x1 black connector, which would be #85 Which is the green wire in the picture,if you are familiar with e38,gen4 LS ecm and wiring.

Its the posted picture with the back side of the fuse box/relays.
Yeah I wish it had a wiring diagram,hahaha
LT1 SWAP does have the number pinouts so I saw that and beeper tested with my dvm so....

[chevelletiger]

Maybe post a pic of a wiring diagram of what you are proposing. I’m having a hard time following what you are asking.

Yes you have to use the 80 psi factory regulator when using a vaporworx controller. Not the 60 psi regulator.

Yeah wish I would have known I could have just used the 60 psi pressure regulator the tech guy fron aeromotive said i needed to buy to use this gen5 camaro ss fuel module, and not have to purchase the vaporworx at over 500bucks.
I know its a awesome setup but not always needed in some applications.
Live and learn.
Oh I figured out a bracket for the fuse box already ill post pictures of it when im done.

Chris bought it.

[chevelletiger]

Maybe you not understanding not like the psi picture with the fuse box.
He specifically said tap into the green wire on the harness with the blue wire from the GT150 Connector.
I wanted to show how it was recommended to do and if others did it that way also.
Donny?? Lol

[chevelletiger]

Not uncomfortable as I did it already.
Just wondering why carl said to tap into the green #50,
x1 black connector, spliced with the blue wire from the GT150 connector from the fuel pressure sensor
#85 on the relay and not the #87 as PSI recommended?
Need clarification is all,and for others that might be doing this on there own

[chevelletiger]

I guess someone got upset and deleted there posts?

Having a discussion like this could help others when installing one with other harnesses besides a holley like the instructions state.
The vaporworx system

[chevelletiger]

Got this mostly done,I just need to run the red wire ign on to the original fuse block and wire up the gauges.
Heres a picture of the LS swap harness fuse block and e38 ecm bracket from aluminum.
Mounted to the right side of the firewall for the fuse box, and next to the glove box for the ecm
