(eventually this page will have more information) Basics When we talk about “OBD1” GM vehicles, we mean vehicles made from (approximately) 1986 to 1995. These cars used several different types of engine controller – some have one injector for each cylinder (Tuned Port Injection, or TPI along with the LTx motors) while some have fewer injectors that are placed near the throttle body (Throttle Body Injection, or TBI) instead. All the vehicles of this generation speak the ALDL protocol for logging/vehicle communication. For purposes of this guide, “ECM” means Engine Control Module, Powertrain Control Module (PCM), Engine Computer Module (ECM) – terms will be used interchangeably to mean the same thing.

Hardware for OBD1 GM Overview 94-95 model years are oddballs. Many of these ECMs support being reflashed over the ALDL interface (e.g. LT1) using TunerCATS. Some (like the 94-95 TBIs) use a G1 adapter. Many Grand Prix from these years use the G4 adapter. Diesels generally use the G5 adapter. The process for tuning OBD1 GM products is pretty much the same for all 86-93 model years.
