In order to run knock free, I run about 2-3 degrees timing less than the Cobb OTS 91 octane maps. BTW, I'm monitoring knock using a MSD Dash hawk and Cobb AP to datalog.
Can anyone explain why our gas is so bad?
| I noticed this too. I am running the 91 program for my 1.8T and gets a lot of pinging when I actually put 91 in. Now I'm running Chevron 94 and there's still a little bit of pinging. |
