I had an A&A Vortech SQ V2 blower kit put on my 2001 Corvette and here's a quick description of my problem. I hope that you guys can help. My tuner is using HP Tuner, so I can't view the file yet.
The car is going fat at 3400 rpm with 18° of timing, but when it runs with
16°'s it's fine. It's going from commanded 12:1 to 11.3:1 at 3400 rpm. He said that he'll probably leave it at 16°'s and just command the AFR to 12.1:1 to make up for the lost 2°. At 3400 rpm/18°, he said that he was getting 2° kr, which I thought was weird because wouldn't getting more gas stop knock? He was still getting slight knock at 16°., Does this make sense to you guys?
I hope that I explained it well enough, but if I didn't, Please tell me.
Thanks in advance!
