1987 Fiero GT: 7170 tune or 7730 swap?
Hello! Thanks for letting me join the forum! I've been working on cars for most of my life, but am new to EFI. My current project is a 1987 Fiero GT that I'm pretty sure just needs some tuning to correct a hunting idle. Somebody has accessed the minimum airflow screw and back-probing the TPS has been giving odd results, thinking I may have to burn a chip to fix the open loop fuel table since apparently they were lean from the factory. A 7730 swap may be in the future since the cold-start injector is dead and a replacement can't be located, but I'm worried about adding a knock sensor since I've seen where people have had issues with that. I've got the .XDF, and .ADS for the $24 mask, TunerPro RT, and my ALDL to USB cable should be in tomorrow. Any advice for getting started would be appreciated!
Will be starting a TBI to TPI swap on a 1991 Firebird Formula after finishing this project - could kick my own ass for pulling the TPI system off an 85 though.
