Adjusting Idle with ECUFlash

Hey Guys!

Im having a very annoying idle issue. My car has absolutely no idle until it reaches operating temp. Before that it dies right out. Before it was tune so you would have to hold the gas pedal until about the gauge gets up the floor then it would idle pretty good, but then after running like that for about a month the car went bezerk and did not want to turn on.

We did some BISS and fuel adjustment to get the car running pretty good and have a pretty good operating idle. But now it would not idle until the car fully warm up. I tried doing some ISCV adjustments to no luck. I feel im missing something.

Any guidance?

Thanks in advance.

Replace your IACV with another one that you are sure that works.
Usually, they don't throw codes.

I had the same issue until I replaced mine.

Not sure if you're still having issues or not but did you check for vac/boost leaks? And if all that good then try adjusting start ipw mscs and set it to what your 14v latency value is (as long as injectors are set up properly) and also raise your cranking ipw.

You can reset your ideling with EvoScan and newly adjust it.
