Can an ECU be repaired??
I am curious if anyone knows if I can send my ECU to a place to be repaired. I can read and datalog the ECU and flash it but the car will not start. I put in the right immobilizer code and I even disabled the immobilizer and still will not start. I put in another ECU and it works fine, but I would like to get this ECU repaired.
BTW this is a 03 EVO ECU with 008 ROM.
Any help greatly appreciated!
Happy Holidays!

Ditto what tephra said. Odds are very good that you don't have a physical problem, but that something is wrong with the ROM you've loaded.
If you believe that you really have a hardware problem, try contacting Steve Piette. He does a lot of DSM and 3/S ECU repair work, and might be able to do something with an Evo ECU.

Steve just got back to me and said he does not do any work on EVO ECU's at this time.
How can I tell if an ECU is fried? I think it might be. I looked at the ECU and nothing seemed burnt. What I don't understand is I can pull it up on OBD2 scan tool, and also flash the rom with ECUFLASH and it still does not fire????? I am at a loss I took the exact same flash and put it on the new ecu (changing immobilizer) and it fires right up??

Since this is Mitsubishi "quality" electronic engineering we're talking about here, look for any signs of capacitor leakage. If that's the case, they'll need to be replaced, and the board under them will need cleaning and some trace repairs performed if any damage has occurred.

FWIW...months ago I only had wastegate boost levels so I took it to a dealer. They ended up replacing both my Powertrain Control Module and ECU to fix it (both under warranty). If you get the car physically back to stock, flash a stock map and have it towed to the dealer. If it's truly a bad ECU then they may replace it under warranty.
They didn't even mention that I was tuned when I took my car to them.
Just a thought if you get desperate...
edit: this was an 03 Evo 8 at around 40k miles in July 2008.
