      Start with trying to reflash the update or try an earlier version. The ECU can be corrupted if the update doesn't program correctly.

        Ouch. Customer sent computer wiring and dist back to eldebrock. They said comp was bad sent new one back. put back in set up dist started motor zeroed timing as program from eldebrock had timing map locked at 20 deg. All good motor is twin turbo 496 BBC so base program was very lean and locked timing but running decent in shop. Using my computer as it has worked on numerous eldebrock and others with no issues, Pick new program with maps closer to power for starting point 555 BBC click update and killed the ecu ?? tried going back every thing seems good writes changes the program but lost dist output no spark. Remembering back I'm pretty sure this was same program as the first time I killed it. Obvious the 555 program is corrupted or it's switched something I'm missing to match dist to ecm . Any Ideas as I'm officially lost

          Specs:
          XT Plus. Injector drivers 2 AMPs max (each). Ignition 8 AMP max.
          XTR. Injector drivers 8 AMPs max (each). Ignition 10 AMP max.

          Could be 555 map is a XTR.

          Or 555 is set up for a different trigger from the distributor/crank.

            71 e 01 8 cyl. fsx flash is on factory disk and reading on eldebrocks website xt plus takes different firmware.
            when using eflash software version is 00 and when in editor program no data is reading connects immediately

              My brains starting to hurt....one of the programs does have a "virtual engine simulator"....it might be the Pro Tuner.

                      It can only use one at a time.
