Irregular Knock really worries me...
Hi Guys,
recently ive set my boost controller to high boost (1.8) and for most of the time whenever i WOT the PFC ecu commander knock register is usually below 25, but yday when i WOT again my knock register 79.
Ive tried few more WOT on different gears (1, 2, 3 & 4) but the knock count remain under 25.
Knock value is slightly higher when doing WOT on 4th gear.
Is it serious???
