Well, got my uberdata'd ecu in there, running a good proven map for a d16z6 with a t3, but modified it to get more feul earlier in the high throttle maps, im running an rbh5, spools quicker, and its also on a d16y8, but close enough. I get no codes, car starts up fine, drove fine for a little bit, about 20 minutes, boosting alot in teh first 5. My a/f stayed full rich though. After driving to my girls house, then driving off, i boosted a quick 9 psi, then put the clutch in, and it stayed at like 4500 rpms. My throttle pedel wasnt stuck, it just stuck at like -10psi on the boost guage and idles at like 4500 rpms. Pulled the hazard fuse, still did it. Sit for a few minutes, and it drove fine again. Drove for another 5, boosted again, and it did it again. Let it sit for a couple hours, then pulled the hazard fuse, still did it. Drove it for like a minute like that, and it went away, studdered a second, then drove fine again, full rich... WTF is going on? i was hoping uberdata would fix my problem. Should i just tune the feul down on the afc before i start the car next time. All my afc settings are back to 0%. Arg....


Oh, and i dont see any obvious vaccum leaks, no hoses blew off or anything, and i tried searching, found nothing for this high an idle....

 

well you can't just run a map tuned on a different motor and turbo and expect it to work right..

I'm not familar with d series motors. I would assume the fuel maps and timing maps are different between the z6 and y8 motors.

And why are you using a afc with uberdata?

your idle problem sound like something with a IAC - if d series even have one. Search on uberdata forum.

 

Well, it ran great for a bit, jsut too rich, but no wit does this, and my afc settings are all 0.

the z6 and y8 motors are so close, it doesnt even matter.
