  • Q.

    What is the EEC Tuner?

  • A.

    The EEC Tuner is an electronic device that connects to the PCM and allows the user to change calibration data. The

calibration data includes things like fuel mixture, timing, shift points, idle rpm, rev limit, and many more tuning parameters set up at the factory. What you can change depends on the type of processor you have and the support that is currently provided in the EEC Tuner software. In a general sense, the EEC Tuner can change any data in the EEC-IV address map from 2000 Hex to FFFF.

  • Q.

    Does the EEC Tuner support non-Ford applications?

  • A.

    No.

  • Q.

    What Ford vehicles does the EEC Tuner support?

  • A.

    In general, the EEC Tuner supports '89 - '95 Mass Air equipped 8 cylinder Mustangs. Specifically, the EEC Tuner

supports processors, not vehicles. The following processors are supported; there are 5 general families that support several processors in each family: A9L -- 88-93 Mustangs Includes A9L, A3M, A3M1, D3D1, X3Z, S0Z A9M -- 88-93 Mustangs Includes A9M, A9P, C3W, C3W1 A9S -- 88-93 CA Mustangs Includes A9S, 8LD PE -- 2.3l Turbo applications Includes PC1, PE, PF2, PF3, PK, PK1 ZA0 -- 94-95 Mustangs Includes T4M0, U4P0, W4H0, J4J1, ZA0 Each family has a specific set of data parameters that are supported in the EEC Tuner software. See sample.htm for the Modification file for a given family.

  • Q.

    How do I know what processor is in my Mustang?

  • A.

    In order to be certain, you must look at the label on the outside of the processor.

  • Q.

    My processor is not listed - will the EEC Tuner work for me?

  • A.

    No - not really.

If you are a developer, a chip tuner, or computer hacker/car enthusiast, the answer is maybe. Here's how. You can use hex addresses to change memory locations to values you supply. The only value to this is if you know that, for example, location 0x8C10 and 0x8C11 is where the idle is stored and it is a value that is multiplied by 4. You could calculate the changes and deposit the new value by adding the following lines to the modification file you download to your Tuner: 0x8C10 0xFA #in this example, this changes the idle to 1000 (250*4). 250=0xFA 0x8C11 0x00 If the previous description does not make sense to you, forget about it. It’s only important for developers and tuners

  • Q.

    How do I get the stock settings for my PCM?

  • A.

    Get a copy of the Ford ROM image using your EEC Tuner. Then use the Parse Binary function from the EEC Tuner

software, specifying the ROM binary file you just captured. The Parse Binary function extracts the stock values for the given ROM file, then opens the file and displays it in the edit window of the EEC Tuner software. The values shown in this file, named extract.eec, are the stock settings for your PCM.

Q. I currently have a chip and want to transition to an EEC Tuner. Can I program the EEC Tuner to use my chip settings as a starting point? A. Yes. Send your chip to ShiftMaster, and for a $25 charge, we will extract the settings and create an EEC Tuner mod file that exactly matches the settings that were in you Chip. This is useful for radical combinations that are running pretty well and you would like to start tuning and modifying from where your chip left off.
