There is an excellent cross-reference I found with google that lists common ECMs, which mask (software revision) they use and various other useful information.

TunerPro RT ( link ) and TunerCATS ( link ) are the two most commonly used software packages for OBD1 GM.įreeScan is a free datalogger that works with some GM vehicles. If you have excel, you can also take a look at this spreadsheet for a list of what hardware you’ll need with various combinations. * Socket Booster ( S_BOOSTER) required for Ostrich 2 emulation and TBI ECMs If you don’t see your application here, please email us. Can be used instead of G2 adapter.ĬABL1– Used to connect an ALDU1 or APU1 and a pre-1995ĬABL2 – Used to connect an ALDU1 or APU1 and a 1995 carĪPU1 – Combines the functions of the BURN2 (programming chips), Ostrich 2.0 (real time chip emulation) and the ALDU1 in one unit Applications Socket Booster – required for use of Ostrich 2.0 in TBI applications. Ostrich – USB Chip emulator, allows realtime changes while engine running Used to read stock program on memcal ECMs. HDR1 – Header that allows reading memcals in a BURN1/2. G4 – Blue Memcal style chip adapter for some 94-95 vehicles G3 – Multiple program switching version of G1 G2X – Multiple program switching version of G2 G1 – “Memcal” style chip adapter (TPI, Syclone/Typhoon, 94-95 TBI, 92-93 LT1, etc.) Instead of buying the BURN2, Ostrich2 and ALDU1 separately, you can buy the APU1 unit that does the functions of all three pieces in one unit. For the 1995 model year, CABL2 is required due to the physically different connector. For 86-94 vehicles, CABL1 is required to connect the logger and the vehicle. Logging from the computer is accomplished using either an ALDU1 or the logging facilities of an APU1. Alternatively, you can either use the Ostrich 2.0 emulator or the emulation facilities of the APU1 to make changes while the vehicle is running. You can burn chips using a ROM burner such as the BURN1/2. The same EPROMs can be used for all of our OBD1 GM products (except the switching adapters…) which is usually the 27SF512 – C2.Īfter a chip adapter has been installed in an ECM, tuning can begin. Some chip adapters require soldering for installation (G2, G2X) but most do not (G1, G3, G4, G5). First, a “chip adapter” is used to convert whatever the ECM in question needs into a form that accepts a 28 pin EPROM. The process for tuning OBD1 GM products is pretty much the same for all 86-93 model years. Many Grand Prix from these years use the G4 adapter. Some (like the 94-95 TBIs) use a G1 adapter. Many of these ECMs support being reflashed over the ALDL interface (e.g. Hardware for OBD1 GM Overviewĩ4-95 model years are oddballs. All the vehicles of this generation speak the ALDL protocol for logging/vehicle communication.įor 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. 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. When we talk about “OBD1” GM vehicles, we mean vehicles made from (approximately) 1986 to 1995. OBD Diagnostics, Inc.(eventually this page will have more information) Basics If you have the GM 16 pin OBDII style connector used on some 94-95 OBDI cars, buy the 16 pin cable.

If you have some other connector configuration other than the GM 12 pin (such as Lotus cars) or a mid-1980's GM car with the serial data on pin D, buy the bare pin cable. Pin M indicates 8192 baud and pin E indicates 160 baud rate serial communication speed.

This cable works on cars that have the serial data pin on pin M or pin E of the GM 12 pin OBD1 ALDL connector, which is most every 1982 to 1995 GM car. See our GM OBD1 home page for references and diagrams of the connectors styles. This cable is the most convenient to use if your car is equipped with the 12 pin connector style, as it allows you to just feel under the dash to plug it in.
