Is there a way to test the MAP & CKP sensor ? I've tried 3 different dynoed maps from the same set-up, & I get excessive knock/pinging from all. (in the 2250-3000 rpm range) Yes the anti knock feature is turned on. I have adjusted the timing back but I am confused as to why I have this problem & others do not. The service manual says excessive knock can be a bad MAP or CKP sensor but doesn't say how to check them.
