myself and another shop updated to the latest firmware and software for our v2 and has since not recognized the controller... it failed on a cm2450 and i tried cm2350 it will not communicate at all shows ignition off error.... it ended up bricking the 2450 and had it stuck at 100% cpu usage where we could not even benchforce it back to life.. luckily a localish fella helped and got it tricked to be able to flash it via v3 flashscan... does anyone else have issues witht the latest software on anything v2 cummins controllers?
