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.
