Mine smelled like burnt electrical and was therefore FRIED.

Look very closely at the ecus processor chip. If it has a small hump in it anywhere it has been fried. They sell on ebay for a pretty penney even if they are fried if its an eprom ecu.

ya well its not fryed but the compasiters are leeking at 3 ta 4 diffrent spots but theres no hump in the prosesser, humm..... salvegable, maby. im going to try this place called action auto parts.

My eyes are bleeding after reading this thread. Learn to spell people, PLEASE
At any rate, if the capacitors are blown or leaking and there's no serious damage to the PCB, just send it off to steve for repair.

How much for a repair? I got an ECU with a cap that blew and how much is it to repair?

I got an ECU with a cap that blew

Based on my experence, it's time to get another. When one of the filter caps blows up (like C108) it usually takes out the voltage regulator and parts of IC111. The voltage spike often takes out the CPU and other chips. The cost to repair is more than the ECU is worth.
