Basically, I was running stage 1 aggressive map on my N55. When I originally flashed it there were no issues and I did not need a battery tender. I am scheduled to bring the car to the dealer tomorrow so last night I go to uninstall back to stock. Everything seems to be going fine and the install said complete. I disconnected the AP and attempted to start the car after shutting it off. When I attempted to start it, the lights and all accessories came on, but the engine would crank but not start and the headlights flashed. Tried to reinstall the Stage 1 map and that still didn't work. Tried disconnecting battery and that didn't work. Tried jumping it via the battery in the trunk with no luck. FINALLY used the "hotspot" negative terminal in the engine bay and was able to jump start it using that.
SO I either drastically drained the battery during the flash OR my dumba$$ may have unplugged the AP once it said install complete before I turned off the car. I really don't recall. Glad I didn't brick my ECU. Hopefully this will be a lesson for others. |
