Hey ppl, i own a 2002 sri turbo, a friend of mine said he could flash tune my car using an ecu flashing tool. first he read the software that was on my ecu and stored it on his laptop. the car still started and worked as it should. then he started uploading the modified file onto the car but for some reason the cars batterey went weak hallway into the file being flashed onto the ecu.
Now the car will not start and there is no engine mangagment light when the ignition is on. he tried uploading the standard file back onto the ecu but it wouldnt work.
We plugged a snap on diagnostic machine into the obd port and it couldnt pick anything up what so ever.
Any suggestions and advice on how to cure this problem?
