    2020 Camaro Communication issue

    Hello Fellas. Looking for some help.
    Working on a 2020 camaro ss.
    We installed a lt4 supercharger, lt4 high pressure fuel pump, long tubes and borla exhaust.
    Since doing so somehow weve lost comm with whats seems to be half the ecu. It reports sensor data on the scanner but anything calculated it greys out the scanner and doesnt report. I have checked the car over for blown fuses, loose grounds, loose connector pins, ect. car has 10k miles on it. I connected hpt on another car and pulls up the data fine. Car starts and runs. Im at a loss here. Anyone have any ideas to check or try.

    Did you move the wire bundle away from the headers when you installed them? If not, check the passenger side wire loom that runs down by the headers. Might have melted them.

    Issue fixed! Simple really. Sent in info log, datalog, channel, was instructed to download the newest beta and repoll pids. Those few things got it back online!
    Thankful.
