Hi all gys
Im very new on EFI Tunig, and need some Ideas from you! Im Located in Austria, and here is no body available who have a plan about US-Cars with
EFI, on my Location all tuners put on a Carb, and oll is fine, i dont think thats the only way to perform a modern Engine.
So i startet a Projekt, on ouer 89 Camaro Iroc was an 305 TBI Engine with a 1228746 ECM Running ANTT. The Engine was out of life,
(Lo Compression, Valves blw by, bearings...)
I put them out, and Swaped to an 98 350 Vortec, put on the Chevy Vortec TBI Manifold
Also put on the 350īs Injektors, knock Sensor.
for basic Startup i take the ANLU bin but actualy it will not work i use Tuner Pro 5 and for chipping and logging moates APU1 (that work great).
The Problems:
Engine Starts very rough and iddle bad, i think it was a Mandatory Timing Problem.
O2 rise up to 900mV go down to 100mv ( no Leak on Exhaust manifold).
Iddle speed is unstable, i think the ECM would correct AFR and Iddle but it is a syncron sin Wave, so the regulator is not able to correct...

Is anybody out there who can give me a tipp to start fixing the Problems...
Ps. I would use the AKNA bin for start tuning, but i cant find one to download..

Thanks a lot
Regards from Austria
