after the turning course with ecutek. I was wondering, in the even the knock sensor break and don't send any signal. would the ecu advance the timing until self-destruction of the engine? can we add a max advance of the self learning?

That's an unlikely scenario, but a great question, and I love that you're pondering things like this.

If the knock sensor is in a fail state and a code is thrown for it, the ECU will not learn additional positive timing advance.

Yes you can also set max dynamic advance and learned advance values.

We usually reply within 12hrs (often sooner)
