I just got my car running today! I had the heads off and got them magnafluxed, milled, new intake valves, and all valve seals, after the car overheated. I blew a head gasket and the heads were warped. The block was rebuilt about 500-1000 miles ago but had all stock parts put back on it. Since I had the engine apart I put on some new stuff to go with it. AFPR, 42.5# 009's from racetronix, 160* thermostat, billit K&N breather, blocked the TB coolant lines, and replaced all the vaccum lines and pcv valve. The thumbwheel ultrachip is on its way, should be here tommorow, can't wait. Also a hotwire kit and some gauges will be ordered real soon.
I started the car today, started right up and no fuel leaks. The car is running very very rich though. It isn't driveable, by just hitting the gas about a quarter of the way black smoke comes out of the pipes. The fuel pressure is set to 42#'s line off, I tried to back off on the fuel pressure but it didn't get any better. I hooked up the scan tool and here are some numbers I got.
O2 0.95-0.99
O2 cross counts 67
TPS volts 0.38
Block Learn 105, Integrator 128
MAF 8-9
Load Variable 50-60
IAC jumps around anywhere from 6-20
Here are the questions. Because I have the stock chip in right now, could that make the car run this rich with those 009's? I know it will run rich because it is not calibrated for those injectors but so rich i can't drive it? Also, my knock retard on the scan tool read 0 but I tried to tap on the valve cover and the intake manifold with a hammer and the scan tool still read 0. Could this be a problem? At one point the car started to idle really bad, I check the KR and it was at like 130, I shut the car off then started it back up and it went back to 0 and remained there and idled better other than the richness.
I guess i'm kinda counting on that chip burned for the new injectors to fix the rich problem, i'm just looking for some insurance or if anyone else has run 42.5# injectors with the stock chip. Any help or insight will be appreciated.
Thanks, Eric
