Hi all,
Can anyone put my mind at ease a little here? I have a stock LS2 in a kitcar, running stock GMPP LS3 map on an E67. Car runs and fuels beautifully after a fair bit of tuning/logging work by me.
I am getting 2-3 degrees of knock retard at high load, but what puzzles me is that the NB O2s are both showing very rich (c. 900mV) at this point. I would only expect knock when the mixture is lean.
Only get it at large throttle openings, and the only strange data (to me) is that the MAP kPA is c. 120 - seems high for a normally aspirated car.
Would anyone worry about this KR?
Martin.
