so I started using my lund N gauge to monitor my car and I noticed that I was pulling 1 degree of timing when I went WOT.
Car is a 2012 GT500 with SW longtube headers/ catless h pipe, VMP 67mm throttle body, JLT 123, vmp pulley/idler combo, mantic clutch/flywheel and the plugs recommended by Lund gapped to his specifications. The gas being used is chevron 91 from California.
I sent Lund a email about it and he stated that it was a gas issue and not a tune issue. He recommended that I try octane booster. I put in a full can of Lucas octane booster and got new 91 gas and it’s still showing 1 degree in
KnockR on a 3rd gear pull and sometimes in second. It will start out at 0 in normal driving and when I go WOT it initially has a -knockR and then around 4400 RPMs it will climb up and stop at 1
I’ve read all the stock computer can pull is 1 degree max so I’m a bit concerned. I asked Lund and he says his tune will pull up to 3 degrees.
I’m going to Datalog the car and send it to Lund but I figured I’d check in here and see what you guys think.
I’ll probably put the car up tomorrow and check all my exhaust as well. Possibly the stage 8 header locking bolts or something hitting causing a false knock? I’m not really sure if it’s false or real and I don’t care to find out the hard way
Thanks,
Andrew
EDIT: please ignore the I'm going in the title. it should just be "1 degree of knock"
