Customer Question

Tried to flash a fuel map onto my 2014 mitsubishi mirage. flash failed with error, car wont start now. i assume i "bricked" the ecu. is there any hope for my old ecu, or am i to buy new (blank) ecu?

Mechanic's Assistant: Has the vehicle turned into a gas hog? And how does it start -- same as usual?

Wont start

Mechanic's Assistant: Are you fixing your Mirage yourself? What have you tried so far?

Lots of things have been tried and it is almost certainly an ecu issue. no spark

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Just what ive said already really

many times. checksum error. ive moved beyond trying to install the reflash. i either need to send the ecu out to be "benched" or repaired (if possible) or buy new ecu and have the vin flashed. am i correct in my assumptions?
Mitsubishi Mechanic: tech0405, Auto Service Technician replied 4 months ago

Yes the flash will not go trough again then you have bricked the eco and you either will need to send it out or have it replaced especially since you are getting a check sum error fault . I hope this helps please dont forget to provide feedback for the help provided thank you
