Re: FAST XFI 2.0 install questions

ok cool. Thank you, I will verify those pinouts on my c100 and probably wind up doing the same. That pretty much sounds exactly like what I’m after too.

Re: FAST XFI 2.0 install questions

Ok, that’s exactly how I have it drawn up too. My car is also a manual and definitely has a speed sensor circuit that wires through the factory ECM though.

Re: 383 build weak spark issue

I’ve got 12v when key is in accessory and it drops to 10v while cranking. That’s at the pink wire that goes “through” the coil and to the distributor. The measurement was taken at the distributor.

Re: Need help starting engine for tuning

So it’s a better idea to dump the modified injectors and get new. Do you recommend 30 lbs for a 383 build? I’ve heard either way. My cam has a max lift of .520/.540.
