Whats it doing? Can you post the tune and a data log?
Don't give up, learn.....
I agree! Don't give up. But more info than just "still won't idle" would help. Is it surging, idling fast, too slow, rich, lean, running a while and dying . . .??? That will help those reading your post and may indicate a problem that's been prevoiusly solved. Also, posting injector and cam specs with an idle issue is helpful because they can be part of the problem. FWIW.Quote:

I think that I need a starting point such as a performance BIN to build off of. I really need help with this.
Whats the KPA like at idle? Timing? Mind posting the tune?Quote:

Thanks for the reply Skinny Pedal. If KPA is referring to the Manifold Absolute Pressure, is at 2.41. I have the timing set at 6 deg. adv. If you have TunerPro, I can PM you the BIN that I'm running. I posted a short data log on youtube, https://www.youtube.com/watch?v=YvRq...ature=youtu.be and a screen shot below.

1987 C-4, your car doesn't use a MAP sensor, so that value is a best guess by the ECM based on airflow.
You need to adjust the MAF tables in order to correct fueling. I'm not real familiar with MAF based systems so I can't really give you any solid pointers on where to start with that.
The first place to check is injector constants and corrections. Ensure the fuel delivery at the current pressure matches the values in the calibration.
1project2many, Where do I find that info. in TunerPro?Quote:
