    Question OS 15166853 DSP5 Tune Crashes ECM (Video Included) RC9's fault?

    I am running RC9 and have my flashscan updated to the latest firmware and bootblock. This occurred on a 2002 LB7 while trying to install a DSP5 tune. When you first flash the truck it would start and go through the tunes just fine, however about a minute into driving the truck the ECM would freeze up. I tried recording it in the scan tool however when the truck would die it would stop communicating with the scan tool. After some time the ECM seemed to reboot itself long enough to be able to either flash or fire the truck back up, only to have it do it again. When the ecm would quit the check engine and glow plug lights would blink very fast and you could hear the relays clicking under the hood. I made the tune several times however each time was the exact same. It would take the tune just fine and start and run fine for a minute or so. I ended up flashing in a single tune which seems to work just fine. I did not get any errors on the flashscan or have any codes from the truck. I have flashed many LB7s however this was the first one after updating to RC9.
