Corvette CCM Reverse Engineering Anyone?

Fair enough. A lot of ADS/ADX files do the same thing; just blast the bus with Mode 8

My intention was to try sending a mode 8 after seeing the 41 message from the PCM that was initiated by mode 9. But I didn't have the message pump accounting for whether it had silenced the CCM or sent a mode 9 yet. Didn't work either way. Apparently the CCM will only honor a mode 8 request for a short time after sending the f0f1 heartbeat.

Wouldn't that be F4 57 07 41 6D? And no luck either way.

This should work nicely. I can separate the 10 and 40 requests between six or eight logging messages so the 07/40/41 exchange isn't adjacent and thus lose slightly less time logging.
