AP-SUB-003 question

Recommended Posts

Can the AP-SUB-003 accessports be modified to be compatible with 05-06 LGTs? They all connect through the OBD-II ports right? What makes the Sub 003 different from the Sub 002? Thanks.

The '07+ LGT's use the new CANbus system to communicate with the ECU while the '05-'06 cars don't. The Sub 003 AP has a different OBDII dongle than the Sub 002 and I would assume is programmed different too so that it can communicate with the ECU. I'm not sure it's possible (or worth trying) to turn a Sub 003 into a Sub 002. You would need one of the Sub 002 OBDII dongles and would probably have to hack the firmware from a Sub 002 to try and force it to install on the Sub 003. Even after that there's no guarantee it would work.

Although, it looks like both AP units use the same firmware which means there's a possibility that the AP's in each box are exactly the same and it's just the dongles that are different. I've never had a chance to see a Sub 002 one to compare to mine.
