Actually, I have been looking for remanufacturing outfits for myself. I have an ECU on the shelf which is otherwise fine, except for the fuel injector/turbo bypass valve driver chip on it failing.okcrum, you listed those the places. Even before you posted your reply I saw ecutesting's facility and knew that THAT would be the best choice. I live in the USA and it would be a pain in the ***.
My questions to you are: Why did you choose those 3? Do you have specific knowledge of them with successes? Which one in that list would you, in my situation, send yours to?
Any other advise on sourcing a 55567225 or similar is welcome. Thanks to the two for you for your opinions!
Now that makes total sense.As for repair services on Trionic8 there are few success stories, but mostly failures, as the most common failed part inside is the main processor.
Now we are getting closer to what I want to know. I am trying to speculate at which fails first (FET or CPU). FETs usually fail to either current or heat and they have a specific operating temperature. The CPU is just sending a low voltage PWM signal so it is unlikely that it is killing the FET. A catastrophic FET failure can send a voltage spike back thru the CPU and damage it. Do the bad FETs burn up totally, ooze from the inside or just go quietly. Do you have any photos of the board or the failed FET?The driver chip for the 4 injectors and the bypass solenoid is a Texas Instrument chip which u can buy original online, but i can tell u from now it wont fix the issue , we already traced it back to the CPU
