    anyway to unlock efi live tune

    What about an 09 LMM ECM? I keep losing communication while flashing my EFI. I’ve checked all the wiring cleaned made sure wires were hot. But now when I check the fuses for it the relay just clicks really fast. Also does it when I test the fan fuse with my fuse light. Any thoughts

    2009 LMM Flashing issues

    Well while I was moving and checking things my ECM came in contact with a hot terminal. Now when I check the ECM battery fuse with my fuse light and every fuse in line with it along with my fan fuse it makes my starter relay click on off really fast and won’t start or give me a check engine...

    Does on star run off the radio as well? Or separate since it’s always on

    Interesting. I do have on star in the truck. Is that as simple as pulling the fuse to shut radios off? I have power everywhere that needs to have power. Maybe closing doors and making all the lights turn off? I’m looking for an all ideas lol. Thanks for your time.

    What causes noise? I deleted and removed my egr. Maybe the egr ground? All those wires are just tied off to the side. My tuner did delete them so didn’t think they were too important anymore.

    Yup. Well back to the issue at hand. Lost communication with ECM when trying to flash it. Same with the ECBM2. Know anything about this? 2009+ LMM 6.6

    I have this exact problem. I’m losing communication with my ECM when I’m flashing it. I did find a ground strap that is not connected to anything but the firewall. It’s only 16” at best. I think it’s part of the fuse box but I can’t find where it broke from.
