In the "Items List" look for the code that you want to change. Double click on the item and you can set or clear the value.

Are you trying to change the item in TunerPro or ScannerPro?
ScannerPro only reads and displays data from the MEFI controller.
TunerPro works only with the BIN file, it does not communicate directly with the MEFI controller. Changing the item in TunerPro just changes the value in the BIN file, assuming that you save the changes. You have to upload the BIN file back to the MEFI controller for the change to be in effect. I am assuming you have the OBD Diagnostics definition files for TunerPro and ScannerPro and the MEFIBurn program for reading and writing to the controller.

Do you have a copy of the tune that is in your engine now? I would suggest that you download the original tune before making any changes.

If you do not have the MEFIBurn program there is a method for clearing the codes using the DTC tool.
