Recently updated my tablet and attempted to reflash. 5% of the way through the tablet tell me that an error occured while writing to the ECU. After a couple tries i gave up, disconnected the tablet and attempted to turn on my car. Now my car is stuck in some kind of security mode or something and wont even turn over when i try to start it up.

I have contemplated taking it to the dealer for service but i currently have E85 in my gas tank and a stage 2 tune. I am afraid that my warranties will get voided because they will most likely find out that ive been re-flashing my ECU and running Ethanol.

I wish this was as simple as connecting the tablet and re-flashing back to my original file but i keep getting the "an error occuried while writing to the ECU" Message.

Any ideas on how i can fix this? It seems like the car is stuck in programming mode or flashing mode?

Any help or ideas would be greatly appreciated.

FYI ive tried disconnecting the battery for half an hour. Also the horn and all other electronics in the car seem to be working fine.
