  • Q.

    Do I need a laptop to use the EEC Tuner?

  • A.

    No. The EEC Tuner kit comes with a AC-DC adaptor that allows you to download modifications to the EEC Tuner

board from your home desktop computer. The power supply is used to power the EEC Tuner board when it is not connected to you vehicles PCM. Connect the power supply and serial cable, download your modifications from your home desktop computer system, then disconnect the power adapter and install it in your vehicle. Modifications that are downloaded to the EEC Tuner are stored in EPROM. They stay there even after power is disconnected. Note that this also means that modifications are not cleared when the battery is disconnected on the vehicle.

  • Q.

    Is the EEC Tuner simply an EPROM emulator? Does the EEC Tuner work like a chip?

  • A.

    Not really, sorta, kinda. Performance Chips and emulators store modified copies of the Ford ROM, while the EEC

Tuner stores only your modifications. The Ford ROM image is copied into temporary memory on the EEC Tuner board when the key is turned to the ON position, then the stored modifications are applied to that stock image. The result is a temporary ROM copy that goes away once power is removed (when the key is turned off). Functionally, with the key in the ON position, the EEC Tuner works just like a chip.

Q. I know the data locations of a Ford PCM that is not currently supported in the EEC Tuner software, but I don't want to give out that information. Can I use the EEC Tuner to tune these vehicles? A. Yes. You have to use the direct address and data byte modifications feature of the EEC Tuner in combination with the All tag. For example: ALL 0x8C10 23 0x8C11 45 0x4678 0xCC 0x4679 0x1F END

  • Q.

    How can I tell if my EEC Tuner is working?

  • A.

    There are two things to check - communication with your PC and Operation with your PCM. Use Shift-F4 to verify

connection to the EEC Tuner. Change the idle to see that the modifications are taking effect.

  • Q.

    When do I use the power adapter supplied in the EEC Tuner Kit?

  • A.

    When downloading modifications to the EEC Tuner while it is not connected to the EEC-IV(V)PCM. Useful when

you don't have a laptop, but do have a home computer or access to a friend who does.

  • Q.

    Will the EEC Tuner work with my Speed Density Mustang processor?

  • A.

    No. There is currently no EEC Tuner support for processor DA1, speed density processor.

  • Q.

    The Tuner mod file, XXX.eec, looks pretty complicated. Can I use the EEC Tuner without being a Techie?

  • A.

    Yes. Find a techie friend, bug someone on the forum, or have your local engine tuner contact ShiftMaster. Or, a

better answer is, only download the modifications you do understand. For example - A9L NEUTRAL_IDLE 900 WOT_SPARK_ADDER 8 # WOT spark adder (Deg BTDC) END The above is a simple modification file that sets the idle 900 rpms and adds 8 degrees of timing at wide-open throttle.

  • Q.

    Do my modifications stay after I disconnect the battery?

  • A.

    Yes. EEC Tuner modifications are stored in EPROM memory and exist until they are overwritten or erased.

  • Q.

    Does the EEC Tuner have any data logging capabilities?

  • A.

    No. However, if you have a Crane Interceptor, you can download the ShiftMaster data logging software on the

ShiftMaster website.
