Well it has been a while since I messed with the prom stuff. I have switched to a dfi setup, but I am working a 730 running on an old Blazer. I think I need a refresher...LOL!
Well here it is, I am running a 730 ecm with the AUJP code. The issue I am having is that the desired idle speed in Tunerpro RT does not match my idle RPM vs. temp. What am I missing? It is like the idle is referencing another table/strategy.

 

Is it high or low? Stall saver? IAC params? Idle spark/VE? Idle overspeed/undersped spark? There is so much it could be.

dfi? direct fuel injection?

 

Well it is following some table because in the Tunerpro RT the idle it is commanding to is lower then what I have in the idle vs. temp table. I have tried to look for other things that might change the commanded idle. It isn't a spark issue because it is hitting the idle that it is commanding.

DFI is Digital Fuel Injection

 

What is the "IAC Cammand Engine Speed Open Loop Offset" ?

I am asking because I am running this thing in open loop right now.

 

AUJP has a hardcoded idle speed limit. It is set to 800 RPM. So can't get it to idle higher then that.

That makes sense...I will just try another base bin.

Thanks RBob
