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 check sum routine is a piece of the ECU code that checks to make sure the program is valid.  When you use the “Save” or “Save As…” commands in TunerPro, TunerPro updates the checksum automatically.  This is why this is not a concern when burning chips – the checksum is updated when you […]

The ALDU1 is a simple logging cable.  It attaches to the USB port of your PC and to the ALDL logging port on your vehicle.  It allows your PC to communicate with your ECM. Basic Connectivity The ALDU1 uses a USB connection to talk to your PC.  It uses the same FTDI drivers that all […]

Introduction The SocketBooster 1.0 exists to provide active conditioning for signals from our Ostrich2.0 and ChipExtender products.  In some circumstances, the logic levels generated by these devices do not meet the specifications of the target device you are trying to use them in.  The SocketBooster remedies this issue by essentially amplifying and conditioning the signal. […]

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 The AutoPROM is a complex device and it can be confusing to get up and running.  This guide is intended to get you to the point where you are connecting to a vehicle and able to use its functions.  Before continuing with this guide, make sure you have the computer that you wish to […]

Introduction Among other things, TunerPro RT brings a new definition format, the ADX.  This is an extended version of the previous file format, ADS.  The file formats are NOT compatible, but you can convert between them fairly simply.  Unfortunately, the automatic conversion utility in TunerPro isn’t perfect so this guide exists to help you achieve […]

The ‘G3’ Switching Adapter (also: Using the ‘EX’ with the G3) Note: This product was updated in 2015.  The original documentation (which still applies) follows with a discussion of differences between the original and current hardware. For placing several different binaries on a single chip for GM applications, the G3 adapter is the hot ticket. […]

HDR1 Instructions for using the ‘HDR1’ Memory Header The HDR1 memory adapter is primarily designed to download the existing code from a stock Memcal. It can be used for other things as well. For instance, if you want to use a UV eraser on your stock Memcal and then reprogram it without tearing stuff up, […]

G2 G2 TBI-Style 2732-to-29C256 Adapter Installation Instructions:Here is a pictorial depiction of a G2 installation in a TBI-style ECM. It shows the following: 1) Disassembly and removal of stock socket body. – Take note of the ‘stock’ 2732A chip orientation. Your 2732A chip will probably be in a little plastic holder. – Try and overcome […]

Notes from EFI Live’s Paul Blackmore regarding using the auto-tuning feature of EFI Live with Moates hardware: Check both axis of the VE table in the tuning tool to make sure the MAP and RPM headings (the ones colored sky-blue) have link PIDs associated with them. The link PIDs are usually displayed as {Link: SAE.MAP} […]

When you set up a Roadrunner in a vehicle, you will often need to force a ‘hard reset’ of the Roadrunner PCM. This is particularly true if you are using a custom OS or changing OS type. For using EFI Live, perform the following: Open up the software, and get the EFI Live Roadrunner Control […]

Good Choices (simple) You have three choices for tuning forced induction on a TPI ECM (i.e. 7730). Not REALLY a good option, but a simple one: use stock code, hack it around to be ok at WOT by power enrichment tables.  This is ugly and only has a possibility of working for low boost setups.   […]

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 […]

Overview The G1 is an adapter that allows a chip or emulator to be plugged into OBD1 memcal based GM PCMs. The GP1 kit is a G1 chip adapter and two 27SF512 flash chips packaged together at a lower price. Compatibility The G1 is compatible with the following vehicles: 1986-1993 TPI & LT1 94-95 TBI […]

OVERVIEW The ALDU1 is a datalogger designed to work with OBD I GM vehicles. The ALDU1 is compatible with the CABL1 and the CABL2, which are interface cables that connect to GM OBD I and OBD II vehicle respectively. The ALDU1 can be purchased by itself, or as a combo with either the CABL1 or […]

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 […]
