Well i just got a scanmaster yesterday and spent all night installing it. It looks great btw. Anyway for about the first 15-20 minutes of driveing in about 30* weather, the knock retard goes from 0.0 to as high as about 4.0. But its usually only in second gear when i give it a little gas. Should i be worried and start looking for problems. I noticed that after about 20 min of driveing around on the highway and in the city i didnt get any knock retard at all even after going WOT from different speeds. Let me know what you guys think please.
