OBD1 TUNER PROGRAM DESCRIPTION

The OBD1 Tuner program is a general purpose ECM calibration editor that allows you to make a wide variety of calibration changes to your vehicle's OBD1 ECM/PCM from an "easy-to-use" Windows arrangement.

The program locates and displays the calibration parameters in standard engineering units so there's no need to work with or even understand hex and binary numbers. We've tried to make the tables simple to understand as they will often correspond to what your scan tool shows you.

With the addition of the appropriate ECM Definition File, the OBD1 Tuner program supports a wide range of vehicles, from 1982 through 1995 including the LT1 and L99 Flash ECM's from the LT1 cars.

Each ECM Definition file is designed to give you access to the calibration parameters required to support major engine modifications, such as camshaft upgrades, Vortec cylinder heads or Edelbrock parts, larger displacement (strokers), Injector size changes, and superchargers, etc.

The sample shown below is a type $42 ECM (1227747) used in standard duty 87-91 C/K Pickup Trucks and Vans. The ECM Definition Files for the next generation of PCM's are considerably larger and include transmission control functions.

This is the ONLY software package available for editing the GM 6.5 Turbo Diesel!

  • ECM Switches - on/off functions for diagnostic trouble codes or enabling or disabling certain characteristics of the engine or transmission

  • ECM Constants - Single value functions such as:

    • Injector Flow Rate

    • Engine Displacement

    • EGR Parameters

    • Fan On/Off Temperatures

  • Two and Three Dimension Tables

    • All values in engine units, there is no Hex code to learn or convert to real world numbers, it's all done for you!!

    • Tables are based on RPM, throttle position, speed, etc. Most are self-explanatory

Changes to calibrations may be made in the table or the graph format

Changes can be made on the table or the 3D graph by "clicking and dragging" a data point.

We sell this as a complete package including 6.5 Turbo Diesel definition files and include an EPROM Programmer (new Automatic version), a quality EPROM Eraser, and necessary MEMCAL and EPROM adapters so you don't have to solder or de-solder anything.
