Hi guys.
Something rather weird happens to my GSX (according to my logger)
I get 0 knock through the whole powerband at WOT with timing generally at 17* , but at partial throttle, every once in a while I get nasty knock sums. It seems to mostly happen at about 4-5K rpms with throttle under 50%.
Once my knock sum went all the way up to 37 and timming pulled to 13* ! The phonomenon isn't consistent though. I can't just reproduce it whenever I want to by meeting all the conditions (RPMs. partial throttle etc...). I've tried playing with SAFC low throttle settings and other stuff, but I can't pinpoint the cause.
Also, since I get 0 knock at WOT, do you think I should up the boost ? It's at 15psi right now, 'cause I don't have injectors and FMIC yet. (I'm running mutt turbo (T04E compr. housing).
