Easy to stall when cold R34 GTR

Postby etang789 » Fri Jun 09, 2017 1:22 am

The car is very easy to stall when cold; for example, when I have to move around the parking lot or when the engine is still cold and stalls when I coast downhill to the first stop sign out of the house. Which settings should I adjust for this?

Thinking if I should adjust the cold idle to be higher

adjusted the " Idle Control - Target RPM "but no use

seems like it is the reaction of the idle control is too slow, but my " Control Proportional " is at 75 and " Control Intergral " is at 100

Any pointers?

If it is easy to stall maybe it is too lean.

Have you figured it out already? Buddy's GTR is having almost the same issue. We will take a look at it right after we finished installing the smittybilt parts on the current Jeep project.

I have sorta solved this problem by replacing with a new IAC valve, so now the reaction time seems faster or it is more effective. How ever I believe can still be better.

trying to solve this for my friends R34 as well. For him I may need to explorer the Zero Throttle control part.

If it is needing to react this fast then there must be a large error. So the base duty must need attention.
