Tuning a supra using an aem v2 started the timing conservative. While monitoring knock volts increasing the timing is not changing the value at all. But assuming it does work cause the volts drops between gears. Is this some thing that as long as there is no knock it won't change. The knock volts read .1992 is the highest it has read. We have added 3 degrees of timing overall tonight not changing the knock reading one bit. This is a single t67 at 19lbs of boost

if you go into the advance settings and features for knock control in sensor setup just make sure it all looks as it should.

you might need to bring your knock sensor sensetivity down or up depending on engine spec. big valves and multi plate clutches make more noise and the calibration table for knock needs to be adjusted to suit the engine. if all that fails change the sensor. could be a faulty sensor ot wiring.

feel free to email me your map i can take a look at it for you
