Hi Sifu's,
what is the permissible Knocking Level on my 4G63T engine? Im currently using PFC L-Jetro with Commander...
Ive came accross 70 on my commander on the Knocking Reading when i full throttle my ride once...
when dis happens my rev feels like a pull back, drop of performance for 1 sec,,,, on dyno machine at each run, it always happens at dat region, thus im not able to pull above dat region, as da a/f ratio fluctuates up...
