I need help from Pro SCT tuners as I'm in the process of tuning this 2010 Roush 427R pump gas 95 and found out there is a very high knock value from Knock Sensor 1 & 2 at idle and partial throttle. After we upgraded the SC pulley with small one the knock sensor become very sensitive and reading from data log at idle around 80 in B1 and 120 in B2 and at partial throttle will read much higher above 200 to 400*
Do you think this is a false knock or real from your experience? I don't hear any knock/rattle from engine at all during idle and partial throttle. from borderline knock table I reduces the timing very low to 12* from 3500 to 6500 on the load 0.600 and above. We also added Torco octane booster to see if knock values will reduce but still no change at all. I can play with the knock sensitivity but this will be last option to reduce the numbers 20-30%
Note: at idle when we open the hood we heard some tik tik little noise from the side of the heads like a rockers sound but not sure if that normal or not. the owner said it's normal but for me it doesn't sound normal at all and I thought maybe that will affect the knock sensors to read very high.
any help will be appreciated.
any suggest will be appreciated.
