Hey guys, I've done alot of searching on this over the past few days and can't seem to find any real answers.
I have a 95 GSR in a 99 civic, it has a conversion harness for obd1 and we are running a 30-1000 ecu.
We have tried numerous things in the program to get it to idle but nothing seems to work. My tuner is very confortable with the AEM software and prefers to use it but we still can't figure out this problem.
We know it isn't an issue with the software as if you take the ecu out of my car, plug it into his h22 with 1200cc injectors, transfer over his map it runs fine.(we even tried the old and new software and no difference) Same with my buddies car with an almost identical setup, put MY map in the ecu and plug it into his car and it idles perfect.
I took the idle solenoid out and cleaned it all up and tested it to see if it was moving properly and it works fine, was a bit dirty but after cleaning it up it was still doing the same thing. There seems to be no vacuum leaks as it doesn't try to idle high it just wants to quit unless you let it idle at 2000+rpm. Any ideas, and thanks for the time!?
And lastly the weird thing that gets me is if I put my chipped crome ecu in my car it runs and idles without problems down around 900-1000rpm? I'm lost what do you guys think, anyone come across issues like this?

 

sounds like your cal needs tuning.

have u tried using the settings from a startup cal? try copying all those settings over.

 

Check your setup for stat sync/distributor sync errors.
Also check your voltage stability/grounds....
