Hey everyone, my car is tuned like shit at the moment, but it's going in for a tune next week. I've been reading up on AFR's and it seems at idle it is really lean. Could this explain why it's hard to start? Would you guys advise not to drive the car too much before it's tuned?
Lean at idle is fine, under high load a few tuners would be tuning for 12:1 AFR on a lightly modded car, while others would tune closer to 11.5:1. The real question is, do you have a timing map/table that you can post up?
Thanks Eric. Sorry for being paranoid, a mate just asked me to watch a Nistune video (he wants to tune his R32 himself) and I noticed that my values were a lot leaner than they were dealing with. SRB_2NV, nah mate, that's basically all I've got at this stage.
Yeah, I've seen idle values in that range on the dyno too, but when the boost comes on, between 11:1 and 12:1 seems to be the safe zone. Just looking at your dyno, it comes on boost really quickly, then stops like its being limited - have you checked the ECU fault codes for errors?
