    Default Re: Finally got my L67 Fiero running

    I'd expect it to be wiring related, do you have a scan tool so you can see the requested gear by any chance?

    Only thing I have is DHP. When I'm scanning it it says 1st gear. then goes to 2 but there's no shift. I can pop off the shift linkage and put it in 1st and i have 1st.. but that's it.

    A friend and I did the wiring. I've gone through all the pins in the PCM, have power to E on the round connector, etc. Just had the solenoids changed too.

    Welp. to bump this old ass thread back up.

    I fixed the trans issue. Come to find out it was the physical PCM. I had the one from the buick in there (and it took the GTP bin file flash fine). I swapped a different service number in there (xxxxxx757) and poof. Trans saw first gear.

    Been driving it daily for about 3 weeks now to work and back. It's pretty fun to drive. Kinda loud but I just installed a Magnaflow muffler and it sounds a little better. Just waiting for the tips to come in.

    Put the turd on the dyno yesterday. Wasn't planning on it but for $50 for 3 pulls why not. There were 15+ other cars that dyno'd so it was get on, strap it down, run twice, cool for a few minutes, run one more.

    First pass I was expecting it to be pretty rich. 9.8:1 af. Woops. Well, better than lean. Then he ran again real quick. Injector Pulse Widths were 20+. About maxed.

    So I leaned it out 5% and also noticed I was only getting 11 degrees of timing (no KR). So I added 4 degrees. 3rd pass it leaned out to 11.5-12ish and my timing was at 15.5. 7-8 PSI on the 3.4 pulley. IPW's went down to 17 after I leaned it out. I think I can get away with a 3.2 pulley and bump the timing up a degree or two and that may put me around 300 WHP. Local track day (rented out) is May 12th. Should be fun .
