I cant find a exact pinout for a aldl on a 91-92 730 ecm. I found (1) but i couldnt read it b/c it looked like it was scanned. Sorry i have a crappy computer. I just got a homeade datalogger from a friend (both of us are DIY newbies) but i cant get it to work right. Im using RT Tuner pro. Thanks

Sorry guys but i found the problem. We were making one for the 160baud style and not the 8192 baud. Anyways i found this link incase anyone has reason to use it.
