car is in the shop now, motiv support has been helping me out, they suspect its the connector on the fuel pressure sensor/ a bent pin.

Do you know what wiring kit they used? I’m hearing this is a common issue with certain ones.

After help from Motiv he was able to get me an answer from Visconti. Some harnesses have 2 wires/pins crossed in the main plug that connects to the reflex. Pin 32 and 24 need to be switched and that fixed my issue after reaching out to everyone for months. I guess visconti knows the issue is out there but doesnt want to make the fix public.

Now it's made public...

Thanks for posting up the results of the fix. I am sure there are others that will find this thread very useful.

Yes, hopefully save someone the time and stress of trying to figure it out. This platform is great, but its missing more DIY people that actually share info with eachother.

Thank you for this info. It is appreciated that you have shared it as I’m about to install everything you have done.
Sorry you had such an ordeal but I’m glad it’s done and dusted

No problem. Good luck with the build, im sure you will be happy with the results as I am. Start saving for a transmission if you are planning to make anywhere around 700wheel. ?

So I was finally able to fix mine, was a wire pinned into the wrong aux on the reflex box, But now when I'm at WOT, fuel pressure cuts to 0 goes to limp mode and then just goes away. Anyone else having similar issues? I have visconti pump, and 1050 pi injectors with EOS port plate, and full visconti harness and flex fuel.
