Yeah the connectcmd thing is to silence chatter. Its not really needed for on bench comms, but in car, depending on the car, the aldl bus can get pretty busy between the bcm, abs, radio, dash, etc etc. Theres some scope traces of the typical data on the bus on the aussie VT commodores that might help you here. The trick is getting the disable chatter in the gap. http://pcmhacking.net/forums/viewtop...p=27761#p27761
