Your attachments don't work mate.

Don't screw with IFR to dial in fueling, set it up for your injectors and leave it alone. If you have to dial in fuelling because commanded and actual don't match concentrate on VE or if you still have one fitted the MAF scaling. Use PE or B3647 to adjust commanded fuel, that's what its there for. Lastly, I always find that I try to keep my AFR's as lean as practical and pull timing to try and prevent knock. Sometimes you can pull gobs of spark and not much changes. This is when you add fuel and start doing the spark again.
