I’ve got a question on knock sensors and the ECU. The bike is a 2002, 135,000 miles, without the overheating ‘upgrade’, burning 87 octane gas on a 95 deg. day.
A couple weeks ago I pulled away from a toll both on the Kansas turnpike, short-shifted into 2nd gear and went full throttle. By 3,000 rpm, it sounded like I had 6 cans full of rocks rattling in front of my feet. At about 5,000 rpm, the sound suddenly quit. I figured the knock sensors finally went to work and had the ecu retard the timing. At the next toll booth (same tank of gas, same outside conditions, engine was not shut off in between), I repeated the test. This time, no pinging.
Questions: Does the ecu remember the timing setting? If so, for how long? Until the next time I restart? If not, why so quiet the next time I did it?
Thanx
