Anybody know what hex to send to get the CCM and the Dash to quit sending crap on the ALDL line? I'm trying to datalog with Tunerpro v5 and I'm getting lots of garbage in the datastream. I know it's not a hardware issue (ALDU1/CABL1) since I can datalog in TTS Datamaster and Tunerpro v4. I'm currently sending 0x56 0x56 0x09 0xB0 in the connection macro with a 5x repeat and a 1200ms timeout between sends. For the dump request I send 0xF4 0x56 0x01 0xB5 and then listen for a 67 byte response (payload 63, offset 3). The the end of the monitor macro just for the fun of it I put in a 10ms pause. I restart the CCM with the same set of hex that I shut it off with. Can anybody steer me in the right direction for getting Tunerpro v5 datalogging to work with the 90/91 Corvette? Any help is greatly appreciated--Thanks in advance--GD
