We don’t have a lot of experience with these vehicles but they have a decent community providing tools for tuning the factory ECMs.  Many of the ECMs can directly use 28 pin EPROMs like the SST27SF512 and BURN2 we sell and an Ostrich 2.0 for live tuning.  Other ECMs use 87C257 chips which require a […]

Introduction The Fox Body Mustang switched to using a Mass Air Flow meter to measure airflow in 1988 in California.  Box codes “A9S” and “8LD” are known examples.  Uses TFI distributor, sequential injection for up to 8 injectors, MAF air metering.  This particular EEC-IV system became the blueprint for the popular A9L / GUFB used […]

Introduction The first EFI ECMs used by Ford were speed-density featuring a MAP sensor and either a manual or hydraulically shifted automatic (C4/C6/AOD/etc) transmission along with electronically controlled ignition advance with a distributor.  They’re commonly found on early fuel injected Ford trucks like F150, 250, 350, Broncos and even early speed-density 5L mustangs/crown vics/etc. Later […]

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 […]

Introduction Some 94-95 Trucks (mostly F150) came equipped with a 4R70W automatic transmission.  Most of the heavier-duty trucks came with AOD-E transmissions and use incompatible ECMs.  These ECMs feature sequential fuel injection, a distributor for spark delivery, Mass-air flow (MAF) sensors for air metering and most importantly are set up to control a 4R70W electronically-controlled […]

Introduction 94-95 MAF Trucks are an interesting breed.  They feature sequential fuel injection, a distributor for spark delivery, Mass-air flow (MAF) sensors for air metering and most importantly are set up to control an E4OD electronically-controlled automatic transmission.  Aside from their original application, these ECMs are commonly used for speed density->MAF conversions on speed density […]

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 […]

Introduction If you are too lazy to read this whole page, you can skip to the “Recommended Combos” section at the end for a shopping list without any explanation. 92-95 Civic and 92-95 Integras are a common hardware platform – there is no sense in addressing specific vehicle or ECU models.  These ECUs are also […]

Introduction 94-95 MAF Trucks are an interesting breed.  They feature sequential fuel injection, a distributor for spark delivery, Mass-air flow (MAF) sensors for air metering and most importantly are set up to control an E4OD electronically-controlled automatic transmission.  Aside from their original application, these ECMs are commonly used for speed density->MAF conversions on speed density […]

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. Hardware Required for Tuning G1 Chip adapter and C2 27SF512 chip required to reprogram ECM BURN2 Chip Programmer programs 27SF512 chips ALDU1 with CABL1 […]

Introduction The 84-87 Grand National was a unique car available in limited production. These vehicles featured sequential injection, distributorless ignition systems and other groundbreaking features. A combination of unusual and off the shelf ECMs/electronic components make for some unique needs. These vehicles used two ECMs. 84-85 vehicles came equipped with the 1226459 and 86-87 vehicles […]

Introduction Early Fox Body Mustangs used a speed-density metering system from 1986-1988.  Uses TFI distributor, 8 injectors, speed-density metering.  This EEC-IV system isn’t as well-supported as the MAF cars that followed but tools are available.  These ECMs have the hardware ID “SFI-SD1” Hardware for Tuning QuarterHorse – integrated device brings unique functionality to the table.  It is a “chip […]

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. Hardware for Tuning G1 Chip adapter and C2 27SF512 chip required to reprogram ECM BURN2 Chip Programmer programs 27SF512 chips […]

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 OBD1 BMWs are an example of how our products get used for applications that we never intended.  Loosely speaking, this range of ECU appears to be in the 1985-1995 range. Many of our tools are “generic” chip burning and emulation tools that target a type (or types) of EPROMs and will work with just […]

Introduction These processors use EDIS coil packs backed by a 36-1 crank trigger wheel, sequential injection for up to 8 injectors, MAF air metering and an electronically controlled 4R70W 4 speed automatic transmission or Tremec 5 speed manual.  These mod motor ECMs speak the standard OBD2 which opens up options for logging using a standard […]

Introduction These processors use a TFI distributor, sequential injection for up to 8 injectors, MAF air metering and an electronically controlled AOD-E 4 speed automatic transmission or Tremec 5 speed manual.  This EEC-IV system became the blueprint for future Ford systems (EECV and beyond) for years to come.  The 94 Mustang with its CBAZA strategy […]

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 Fox Body Mustang switched to using a Mass Air Flow meter to measure airflow in 1989.  Uses TFI distributor, sequential injection for up to 8 injectors, MAF air metering.  This EEC-IV system became the blueprint for future Ford systems (EECV and beyond) for years to come.  Initially hindered by a lack of datalogging […]

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. Hardware Required for Tuning G1 Chip adapter and C2 27SF512 chip […]
