Used for years on 1993 suburban, 1991 GMC k2500, and 1991 firebird, but only the 1991 GMC connects and receives data in 2023.
1. Cable doesn't pass tunerprort check for valid interface, so Suspected a cable problem. sent to OBD for testing. He said it works fine even with newest FTDI driver.
2. Suspected laptop, so installed Build 5.00.9995.00 on a different Windows 10 laptop. Still only works on the GMC
3. Tried debug mode on the suburban using BANF.BIN and $85-16147060-V4.4.adx
