lots of knock on low rpm
Posted: Sun Oct 16, 2022 5:33 am
Dear forumer,
I've been using +3psi base map for a few months. I notice a lot of knocks when cruising on low rpm. it can get easily 20-40 knocks in a 40mins run in hot weather. I tried adjusting the ignition timing, different intake profile (Mishimoto/AEM/Injen), and individual cylinder ignition trim but the problem still persisted.
attached datalog and calibration here, any help is appreciate!
thanks!
Mod:
1. MST SRI intake
2. unknown brand ... exhaust with exhaust thermal wrap.
