Has anyone here installed the BEGI FMU? I just installed one on my car. I like it, but I am having problems tuning it. Any tips would be appriciated.

did you set base fuel pressure to 43.5 psi or whatever? (stock pressure)

I believe you have to set your baseline before you do anything else.. IIRC

they said in the manual to start at the highest setting first (way rich) and turn it down from there... I'd use a wideband to get desired lambda

cheers

I did set the base psi t about 40/44psi. I think I found my biggest problem. I had a brain fart and hooked up my fuel pressure guage on the return line..... yah, i felt stupid. buuut, it's runnning great now. I hope to dyno soon. Thanks for your help.

do you mean the return line just past the FMU? or the return line just before the FMU?

I dont know if I helped, but it was worth a shot.
