I started getting a slight high count on my r34, 25-30, then one day i got a random 150 on my power fc!!! but the car was running sweet no pinging at all (and at 150 the car would hardely run).
i took it straight to my tuner and he took out a shit load of timing as a saftey precaution. he had the thing for a week checking different things done so many power runs it wasnt funny. out of every 5 runs he would get a wierd 100+ count but he had his own knock detection set up and heard nothing i was even there!
the motor has forged internals so should withstand higher than normal knock but no knock is the best, car runs sweet tho...
but any ideas faulty sensors etc?
