I have a stock ECU. Everything I've read says to set the timming at 17-19 degrees. I'm using standard 92 octane. When should I start to hear knock? Other vehicle I own (Toyotas) have very loud knock when I advance the timming too far.
When I set timming at 17, my vehicle surges between 2000-2500rpm at constant throttle. The higher I set the timming the less surging I have. What is the maximum safe timming?
