Ecu from my engine is out of order. I still can read memory and fault codes , do diacom tests etc but no ignition. No spark at the plugs . I remplaced ECU from friend's engine, and it fired up right away. Can it be repaired ? Or someone has spare one?

It's a MOTOROLA ECM0402, serial 892204, 09-28-2004

Whipple can repair them depending on what's wrong with it. They fixed a broken pin in mine and it works fine now. If I remember right it was $400

the ecu needs to be opened up to see whats failed.I have a 555 that I use to rob parts out of.
can you open the ecu up and take some pics?

I already mailed dustin @ whipple twice but no response ...
Not being specialist in ECU's Not my best option to open it myself ...

+1 Whipple, they fixed my IAC chip

He fixed it again

hello......any chance this thread is still alive?
Can you tell me how to get the pcm-555 case open?
I'm bending it all up.....
Thanks- jim

MAN THEY HATE WATER TO.

they hate a big voltage spike as well.

You have little by little pry all around the case to get them to open. What are trying to do ?
