 'ALDU1 and CABL1'  'ALDU1 and CABL1'
This is for any pre-1995 (OBD1) GM vehicle. Everything except the 1995 LT1. You should be able to datalog all of them, and reflash the 94 LT1 as well. Comes with XtremeALDL and NewCABL1 (RJ45/Moates-specific new style). There's a switch on the side which allows you to select 10k (across pins A&B of ALDL) or 'Open' mode. You use the 10k mode for older TBI and TPI setups, and the 'Open' for newer Speed density and LT1 stuff. This item can be used with TunerPro RT, TTS Datamaster, TunerCat reflash for LT1, WinALDL, and EFI Live V4(OBD1).

Introduction TunerCat OBD2 Tuner is a software package that allows tuning of 96-current GM vehicles.  For some early 96-97 vehicles, it is often the only solution. TunerCat OBD2 Tuner must be purchased with our RoadRunner hardware (either with a complete RoadRunner ECM or just a RoadRunner Guts kit)  due to licensing restrictions.  TunerCat OBD2 Tuner […]

Introduction Unfortunately, the 1226870 is an oddball one-year one-model ECM that was only used on the 1985 corvette.  It is for a TPI setup with an electronically controlled distributor and features 160 baud ALDL communication for logging.  It is a unique ECM.  There are no other ECMs that are a “plug and play” swap without […]

While we try to produce and support products for as long as we can, we can’t continue to make things forever.  Often, product changes are prompted by the components required to build a product no longer being available for us to purchase (“End Of Life” / EOL) – if we can’t buy the chips needed to […]

Introduction This is one of the first electronically-shifted transmission applications.  Some 1991-93 vehicles came equipped with 4L80E transmissions and 16147060 PCMs.  This is a P4 generation ECM which speaks ALDL at 8192 baud and have removable “memcals.”  This was a one-year PCM which was followed by the 16168625 / 16197427 in later years. Hardware for Tuning […]
Intro This is intended to provide a brief overview of the steps required to get up and running tuning an OBD1 GM vehicle.  It is deliberately vague.  Instead of providing an exhaustive guide here, there are a series of links to smaller tasks and explanations.  94-95 LT1 vehicles are going to be an exception not […]

Introduction The 88-93 VR Commodores use the 1227808 ECM which is basically the same as a US 1227165 ECM that is limited by hardware to 160 Baud communications.  These ECMs have torque converter lockup control as required for a 700R4 or similar automatic transmission. Hardware Required for Tuning G1 Chip adapter and C2 27SF512 chip required to reprogram […]

Introduction The 93-95 VR Commodores  use several different ECMs that fortunately use the same tools for tuning.  These ECMs feature electronically controlled automatic transmissions ( 4L60E ) as well as engine control.

Introduction The 1993 Camaro / Corvette LT1 PCM 16159278 is an oddball.  It was not used before or since.  The $DA2 mask was used in Y-body Corvettes and the $DA3 mask was used in F-body Camaro/Firebirds.

Introduction Starting around 1992, GM started putting the newer electronically controlled 4L60E and 4L80E transmissions in their trucks.  Along with the electronically controlled transmissions came new ECMs that speak ALDL at 8192 baud and have removable “memcals” – 16197427, 16196395, 16156930, 16168625.  These ECMs are largely interchangeable – as a rule of thumb, any of the 4 […]

Introduction The 96-97 F and Y bodies use a unique PCM that is an evolution of the 94-95 ECM but requires unique tools.  They are primarily tuned by reflash over the OBD2 diagnostic port, NOT by programming and replacing chips.  (Although this is theoretically possible)  They have both MAF and MAP sensors which are both used […]

Introduction The 94-95 F and Y bodies are a dramatically different breed of PCM compared to earlier models used by GM.  They are primarily tuned by reflash using the ALDL protocol over the diagnostic port, NOT by programming and replacing chips.  (Although this is possible – they feature two 28F512 PLCC EPROMs)  They speak ALDL […]

Introduction The 86 throttle body injection (TBI) system was the beginning of GM’s transition from carburetors to fuel injection.  This is the first of the “classic” speed-density computers which featured a MAP sensor for airflow metering.  This fundamental airflow model was used largely unaltered in later designs.  P3 generation ECM, 160 baud ALDL communication, 24 […]

Introduction The 91-93 Syclone trucks and Typhoon SUVs were a unique low-production vehicle that featured a powerful turbocharged 4.3L V6 engine.  They use the 1227749 ECM, which is most similar to the 1227730 used in the 90-92 TPI V8s.  These vehicles were equipped with a 2 bar MAP sensor from the factory along with hardware […]

Introduction The 86-89 F and Y bodies were among the first EFI computers used by GM that featured a Mass Air Flow sensor (MAF) for air metering.  P4 generation ECM, 160 or 8192 baud ALDL communication (depends on code mask), “memcal” with 27C128 EPROM.  Many of these ECMs feature a cold-start injector.  They can drive […]

Introduction The 90-92 Firebird and Camaro were the first of the P4 generation computers which featured a MAP sensor and speed-density for airflow metering.  These fundamental airflow models were used largely unaltered in later designs.  P4 generation ECM, 8192 baud ALDL communication, “memcal” with 27C256 EPROM.

Introduction Creating definitions for datalogging with the QH is a complicated, involved process.   Regardless of which software is being used, there is a common core set of tasks that need to be done to allow meaningful real-world data to get spit out. Overview Before I get into the specifics, it probably helps to understand […]

94 and 95 were also kind of odd years for GM computers as they transitioned toward OBD2. There are several groups of ECMs. 94-95 LT1,LT4,LTx: These can be tuned via TunerCATS ( link ) with the $EE definition and an ALDU1+CABL1 (94 – square ALDL style connector) or ALDU1+CABL2 (95 “D” shape OBD2 connector).  These […]
Lately, we have been getting a lot of questions from people with 96-97 GM vehicles looking for a tuning solution.  Unfortunately, these are transitional years where the electronics are incompatible with either the earlier and later computers that are well supported. There are a few solutions for people with 96-97 computers: -Convert to a 94-95 […]
(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 […]
(eventually this page will have more information) The main product that we make for 98+ GM vehicles is the RoadRunner emulator that allows realtime changes to be made to a LS1 ECM. The RoadRunner is designed to be used with either EFI Live or TunerCATS software. EFI Live is a comprehensive tuning software package that […] F.A.Q Last updated 2-03-06   GM tuning Frequently asked questions You can use the ALDU1 and CABL2 together for both datalogging and reprogramming. Just get you a free trial version of TTS DataMaster and then get you a copy of TunerCat with the proper definition. Do I need an adapter to get the chip […]

The RoadRunner is the only available full blown emulator for LS1 PCMs – unlike other “emulation” software, the entire contents of the flash is emulated Real-Time, not just certain maps.  It can also be used as a general purpose emulator in custom applications (Bosch Motronic, BMW, Miata, Nissan, …)  It is designed for PSOP44 chips […]

The Autoprom was the first Moates device. It is a combination Emulator, Chip Burner and Datalogger. Today you can buy these devices separately, however this package eliminates the need for 3 separate units. Compatibility As of writing this article, the only software known to be fully compatible with the Autoprom is TunerPro RT.  TunerCat OBD1 […]
