I tried doing this to no avail. I didn't notice anything different, it still stalls.

I have a 95 3000gt I had the same exact problems as you tried everything new IAC, new throttle body new, new iac gasket, replaced all vacuum lines! even raising the iddle even more and still.. i got used to stopping at lighs and stop signs without touching the clutch at all... for months.. really used my break pads lol

also couldnt use my AC...

how the problem got SOLVED! is when I installed a under drive pulley... Yea they say is bad for your crank.. bla bla bla.. honestly there are 3000gt with 500hp++ with that pulley and never seen one post of somebody spliting their crank in half...

so maybe u should try it...

It works as soon as the speed sensor is over 5mph. It has been thoroughly tested by me and EvoM friends in the ISCV control disassembly thread.

I think this table may help him.

This is happening to me also. My tuner hasnt been able to figure it out either. Is this is a new issue possibly with the new Tephra? Just grasping at straws here before I replace my IAC

No vacuum leaks?
Tell him to try stock ISCV values, then go into SAS mode and turn BISS screw to your desired idle RPM. Let the car relearn.

Do you have cams? If so raising timing would make the idle a little stronger.

domyz, He has kelford 272s.. I raised the ignition timing in those areas where it was going to stall previousily. It is at 12 degrees.

Adjusted the target rpm idle to 1000, when the ac is turned on it instantly goes to 700rpm, even though the target is set higher. adjustment screw on full blow was set using Biss screw adjustment method in evoscan.

No boost leaks, as that was verified. everything seems to point to the iac at this point IMO

^ You are the man Warren.

Damn IAC is like $305 bucks. Just hoping it was something else before I swapped it out.

I know they are not cheap, I would suggest getting a used one art, but have the owner verify the voltage and ohm readings on the contacts prior to buying. I have seen them as low as 80 bucks. Explore that option first.

Try maxing out the ISCV demand tables and start the car, it will validate that it's not working at all.

Ok, I'm bringing this back from the dead. Can anyone help me with this? It's heating up and I need to use my A/C and I am still suffering from this issue even after putting in a new BR 2.3L so I know it's the tune. I have adjusted BISS, check for boost/vacuum leaks, played with all the ISCV etc. tables but have not solved the problem. Somebody must know the tuning fix for this. Please share!
Thanks.

Mine used to do the same thing. So I took out my a/c. That and the FF 6466 didn't want it lol.

What I did to fix it was to change out the stick blow off valve to a aftermarket bov.

Theres tons of info on guys that have experienced this issue and what to test but nothing there is rarely anyone that says one specific thing worked. Have most of these guys just dealt with their cars stalling when coming to a stop or just not running their AC's?

Do you have a table in the MAF section of your xml called

MAF Pulse Frequency Limit
or
MAF Airflow Limit

something like that anyway.
