How do you guys keep the idle from dipping down so low after reving??....

Im giving my friend a quick street tune, just to be sure his new build is up to par and not leaking or giving any problems, then he will take it in to get it fully tuned later on boost with neptune...

He has a lighten flywheel with twin disc running on 1000cc injectors...and crome does not have IACV control what so ever...i can get the car to idle rock soild but once u rev it, or come to a stop...dam thing dips down all the way and most of the time kills the car....

Unlike hondata where you can control the IACV and thus control it from dipping down...but im out of ideas on how to keep this car from dying or dipping low...

i only have problems with larger injectors and lighten flywheels...

i cant wait til Ectune comes out...hopefully it has IACV function...

 

Get on the pgmfi forums. There is a thread with a unofficial release of crome with iacv control.

 

i know they had one...last time i checked it wasnt a workable iacv....but ill check again..

 

go into the thread that user XENOCRON made called i belive "Crome timing issues" or something around that name. in the first page there is a version of crome with a working IACV slider.

also go into the advanced tables and set all the target idle parameters to around 1000 rpms. thats what i do and i dont have a problem with idle. i use to, but after using this version of crome and set n rpms to 1000 i havent stalled out once at idle

 

so this kept it from dipping low correct and not stalling?

 

i have/had the same issue while using uberdata. i added more fuel below the target idle rpm and it seemed to help that problem. while it may still dip below the 1000rpm it will never bog out or stall on me.

so if your engine idles at 1000rpm around 20-21" of vacuum you should add like 5-7% more fuel at 500-700rpm in the same column. try it and see if that helps. it helped with mine it might help with your setup as well.
