    It works fine, I just tested it on our bench 6.7L ECM (see below). In the scantool connect to it as a "CMB CM849 Cummins" and it'll talk with the 6.7L.

    Cheers,

    I scanned the 6.7 yesterday and found a couple of codes. I was able to log rail psi, throttle position, and a few other things. Found out his fuel rail valve was popping off. He had it at the dealer numerous times and spent over 4k on it already. This was a quick simple fix. Thank You EFI and I look forward to further developments on the 6.7

    The scanning worked!, I am surprised as the data streams are specific to each ECM type, I didn't think there was any way the 5.9L would match the 6.7L on any account.

    Just some of them. Desired FRP was off it seemed. Actual FRP was accurate. TP was accurate. I can't remeber any of the other ones. I did not try reading it, I might go try that. I didn't think it was supposed to work either but, I had to try

    Not really because we still have to check and confirm every PID, even if some match.
