(Not for my F Body though)

I just crammed a 3400 SFI in my 1991 Z24, i'm still using the 7730 ECM. I'm currently running a chip tuned for a stock 3400 (mine's not so stock).

Here is the problem... normally on decel the IAC should open up a bit to keep the car from staling when you come to a stop. This new chip dosen't do that and it's kinda annoying... I'm waiting to finish my headers before i work on the other tuning issues (BLM's are in the 140's under load) but i'd like to fix this little issue.

I'm using TunerPro with the $A1 def, if anyone could point me in the right direction it would be much appreciated.


Thanks,
Dave

 

IS the speedo working? I know after my motor swap that I forgot to plug in the VSS and it would stall every time I came to a stop.

Hope its something that simple, sounds like a great project

lol, yah. everything works fine. The computer occasionally goes into limp mode which kinda has me worried.. if i shut the car down and start it right back up it runs fine. no trouble codes other than A/C switch fail and since i have no A/C i'm not too worried about that. lol

here is a pic of the car/engine...
