Sometimes the Ecutek software detects knock even when the OEM ECU does not. This discrepancy is the problem a few folks are encountering IINM. So it's really just a software programming thing and not the actual sensor sensitivity - I realize I did not post that clearly at all. Also, please note that I'm no expert but I have stayed at a Holiday Inn Express before
Can confirm. I've had the CEL on a few times for knock after EcuTek tuning, and set up my bluetooth interface to verify. Turns out, the knock sensor reads my flywheel engagement when I shift as knock, particularly when I'm forced to do frequent gear changes in stop and go traffic on I95. A little reading showed other people have had this issue in the past.
