How is it possible.....knock
 

All I did was add some fuel to the PE table and I'm now getting knock across the board in even the low rpms.

Should have asked you at the track, what kind of plugs are you using?

FTR, Wayne is only getting KR while in 2nd Gear. Very strange. Looking at the rpms, MAP, MAF, LTFTs, etc there seems to be nothing really odd, except the O2's are like 100 off, B1= 780 B2= 880 type of thing during second gear. In third gear the O2s stabilize.

Hey Charley, I'm using NGK TR55s. Gonna try and play with the High Oct table a lil more. Seeing as how I'm getting the right amount of fuel. I think I might have an exhaust leak on the drivers side. Plus that O2 sensor is real old. The stock one. I changed the poassenger side one.

Try some TR6 plugs. Lot of ppl have KR from stock and 55's during hotter summer months. Throw a set of 6' in and see whats up. I have a test set you can use.

dropped the high octane table a lil 2 times and Im still getting it.

Is it still in 2nd gear only?
