I tuned a 04 LB7 Saturday and when I got done with the flash the relays in the under hood box were clicking on and off rapidly and the glow plug and security light was flashing on and off. and all it would do when I tried to start it, it would just bump the starter every couple of seconds. I tried to flash it with my bench harness and it would not respond or would not allow it to be read. I had a spare ECM and I flashed it and got him going. the DSP5 setting 2 and 3 had some off looking values in the main injection tables before I even ran the stock EFi live script. I'm wondering if the dsp5 file is corrupt or something. I didn't want to the flash the Dsp5 file in and kill another Ecm. any ideas?
