TUNER PROGRAM DESCRIPTION
                                                
The Tuner program is a general purpose ECM calibration editor that allows you to make a wide variety of calibration changes to your vehicle's ECM/PCM from an easy to use Windows environment. 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.

With the addition of the appropriate ECM Definition File, the C.A.T.S. Tuner program supports a wide range of vehicles .

Each ECM Definition file is designed to give you access to the calibration parameters required to support major engine modifications, such as Cams, larger displacement (strokers), Injector size changes, etc.

The example shown here 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.

                       
                           
Key calibration parameters, selected from a drop down menu, can be easily viewed and edited. 
       
  • ECM Switches  - off/on functions
  • ECM Constants - single value functions such as:
    • Injector Flow rate
    • Engine Displacement
    • EGR parameters 
  • Two and Three Dimension Tables 

    • All values in engine units, (no Hex)
