Not sure if the ecm keeps a record of dates for ignition cycles etc. Just curious.
It might especially if the BCM also records the mileage along with the speedometer.

As far as I know, the ECM, BCM and speedo all have mileage and stay in sync once they are married. If you have one of the three workig on a bike, with the proper tools (digital tech), you can restore the other two devices and maintain the actual miles. I do not believe the BCM records ignition cycles.

You would think that an ECM removed for a TMAX, and then put back in for some legitimate reason would get the actual mileage form the other dcevices. But, I've never tried that either.
