Hahaha, I just want everyone to know that this has been running on my big single car for a long time now and I have not had any issues. :)

Sam
Can you show us some before / after logs? LPFP and HPFP vs. RPM etc. thanks.

There is no need to run a return line right.

Any side effects from leaving it on, doesn't look like it from the logs but I never done one of these before

Cant upload log, extension is not allowed

well you didn't waste any time I told you you would have it before Christmas LOL.... if your system already had a return it won't hurt anything if you leave it there. Our new upcoming fuel system will not have a return, doesn't mean it will effect anything if you have one.

It's working very very nicely, worth every penny guys.

The wiring is the best I've seen in any kit, just the right length and looks like you put a lot of effort/thought into it before release.

It was nice and simple to install.

I'm glad to get this as I was pulling the relay socket connection out it was deformed from heat.

The wiring supplied by fuel-it looks to be way to small and running very hot by the looks of it.

Awesome work, the kit is a must have if running a stage 3.

I second that! I got mine yesterday. I didn’t waste any time and I installed it. Installation was a breeze. I’m running a stg 3 LPFP along with it and its running flawlessly. Here are few pics:

I see he even made custom pnp ekp adapter bracket

Not 100% sure but I think its because the fuel pressure started to creep over target due to the throttle closure so the ecu was dialing it back

Can the BPM4 also log things like rail pressure, boost, stft etc?

Excuse the ignorance, but why is there a dip in fuel request while at full throttle?


Marty is correct, the controller is doing what it is asked to do by the DME. Could be throttle closure wheel spin etc, and the DME is requesting less fuel at one of these events, so the BPM4 throttles the pumps accordingly.

Just updating

This is what was happening to my wiring as it wasn't big enough from the kit supplied by fuel it, mind you it was almost three years old but still an accident waiting to happen.

I've seen people post about it before, but i thought they wired it wrong
