I'm am tuning my first E38 LS2 and I have the MAF tune dialed in fairly close. Attached are my config, hpl and hpt file. I have the wideband signal going to our dyno so don't look for the signal in the hpl. The MAF Disable/Enable are set at 200/100. A/F is 14.7/14.9 at 900rpm idle and has a smooth curve to 12.9@5000 which is the highest I have taken it so far.
My questions are:
1. How much spark advance should I be running at WOT at 3-5000rpm?
2.The horsepower is peaking at 4800 rpm, is this unusual for the LS2?
There is no obvious KR, the car is making 396rwhp on a Mustang IMP-SE. The pull recorded was in 4th gear.
Any thoughts/recommendations?
