    looking at mine and NomakeWam's 90 CCM files. I don't think the Passkey addresses are correct. Also the flags I don't think are correct for the 1990.

    I think the Passkey is at $B69F, I think the LT5 flag is at $B6CA as that is different between the L98 bin and LT5 bin.

    These are guesses based on the relative location based on what I see in the thread. I will scan the others this weekend

    Not sure the mileage is right on mine for some reason, but I will let you guys take a look

    EDIT: I see Nomake's Passkey is 11

    for my BIN, Vin is correct, I have a C60, ABS, 6spd and LT5. My Passkey is 14

    looking at the hex code, my mileages is close

    I think I found everything, but need a favor. I want to test the CCMs on the bench. HOw shall I wire up the RX and TX to the CCM for test

    Thanks
