I read the ROM from my ecu fine this afternoon with the intension to try 9653 v7 on my e ecu running 9055 v5.1. The read rom was fine i was able to save a copy of my ROM then i tried to upload the new ROM to my ecu, it gave me 3 lines and then it gave me an error. I have attached a picture of the error message it gave me. Can anyone please help me to regain access back to my ecu. Thanks much in advance.

 

Looks like you are trying to load an Evo8 rom into an Evo7 ECU - on an Evo4 chassis?

 

yes that is correct. The test write went through ok. But the actual writegave me that screen. Is there anything i can do to regain control over my ecu?

 

possibles:

not enough battery voltage
cable or connector is broken
memmodule has been changed

 

ok last night i tried what was suggested with ecu unlocker and it worked. I downloaded ecu unlocker leave it in the background and launch ecuflash and tried to connect to the ecu and was able to read the ecu then i reflashed it with my 9055 v5.10 ROM and it fired up immediately. Thanks much guys for all the help and advise.

 

what init number did it show and did you change it back to 1?
