put better gas in like ms109, if the knock is still there its "false knock", Lund will turn down the sensitivity once its confirmed....my s550 had this and my s197 had it....thats how it was dealt with and in both cases i was bottom 9 and high 8 sec cars.
how is putting oxygenated race gas for a boosted car thats not tuned for it even remotely a good idea?

NVM I'd listen to this guy...:headbonk:

I saw that but looked to be false knock. Timing is not commanded high enough to have true spark knock.

Fuel is correct, I trust Lund.
I know you think fuel is correct cause they say it is, but do you really think they are commanding it to oscillate between .73 and .8 lambda right after tipin?
