Hey guys, Gonna swap the clutch fan set up on my 1991 GTR to 2 12" electric fans. I saw the pin out (#28) on my ECU that I wanna hook them up to with a relay. I was looking through the software and didnt see anywhere I can trigger or set the temperature to turn on the fans on. Can I do that wit...

I'm still running the stock injectors, it cruises around 14.7-15.3ish.

I got a question about my idle AFR. It sits pretty lean (15.4-16.4 +/- a few ) it jumps around a lot. I wanna bring the idle down to a good AFR.

Do I adjust the timing at idle (currently at 20°) or mess with the fuel trim, or K constants?

Thanks for the help in advance.

sorry to bump an old thread. Im getting around to installing the LQ9 coils on an RB26 but before I did so I wanted to make sure that I understood the Dwell settings to prevent from blowing up my engine. I read through the Nistune Mapping guide found here : http://nistune.com/docs/Nistune%20MAF%20Tec...
