Question on Greg's inj info....dont worry I bought the DVD

Greg or James

When you are scaled 50% and get a MAF afr err of lets say -3%, do PASTE SPECIAL multiply by half or the whole % error?

When using scaled injector/MAF/volume calibrations, you should still be able to make 3% change to the scaled values based on a 3% lambda error. That's the beauty of doing the math correctly with units of lambda (relative richness) and grams (whether they're scaled or not).

Lambda tuning from now on.

It's not a question of reducing the sensitivity, but rather just realigning the same sensitivity values with new g/cyl axis breakpoints that correlate with the new scaled airmass.

However, in practice this hasn't been a huge issue for knock. If you've done the base fuel and spark calibration properly, there's almost no knock to worry about correcting in the first place. "Mr. Miyagi say: best block, no be there."

Greg, the reason i asked this is because I am getting a lot of KR while slowly accelerating, not yet under WOT. Then While accelerating in 3rd i get nothing, but in 4th it gets really bad. Even when i let off, i get like 4-5 deg. I have scaled all the known areas, MAF, IFR, Hi Octane and low, and basically all tabs with g/s. I dont have an aggressive timing table and PE is around 12.7-12.5.
