Datalogging with stop prom
I never got a chance to do some datalogging with my stock prom, I did mods then went to the ARAP bin. What kinda knocking occurs with a stock motor and stock bin in our cars? Does the factory cut the timing back far enough to eliminate all knock? Just wondering??

That is both with my stock ANYJ9304 and with the ARAP code. Any more than that and your motor probably isn't very happy about the new spark table, or maybe your base timing isn't set correctly. Should be 6 degrees...
