Thread: I/O mapping, program shutdown problem.

  1. #1

    Default I/O mapping, program shutdown problem.

    Having a little issue, setting up my ECU. I import the Global File, make the required changes, save, transfer to ECU, everything looks good. If I disconnect from the ECU and shutdown the Holley program on my laptop, I get an I/O mapping error and the program shuts off by itself when I try to reconnect. It only happens if I close the program, if I reinstall firmware, import and save Global File, but never shut off the program, I can reconnect to the ECU all I want. Sorry if it's long winded, it's been a long day. Any help would be appreciated.

    That seems like corrupted EFI software or a corrupted Global File. First try deleting & reinstalling the Holley EFI software. If not, then rebuild the Global File from a base calibration.
    May God's grace bless you in the Lord Jesus Christ.

    Thanks, I think it was the V4 EFI software, I dumped everything, downloaded V5, had my tuner send a new Global File, everything works.
