I'm gonna get my car dyno'ed tomarrow. But since i have false knock i wanna install my knock module before i go. If i install it i have to disconnect my battery and reset my ecu. How long will it take for the computer to learn everything. The drive is about a 1 hour drive. Will that be long enough?

 

Yes, it's a good idea to always disconnect the battery when working on the PCM.

The computer re-learns every 10 minutes.

 

The circuitry for monitoring knock needs/has no learning. It is an instantaneous thing.
