The very nice and knowledgeable gentleman at avproecm spent a good 10 minutes talking to me. He swears up and down that he has never seen, or worked on, a Mitsubishi MD306933 ECU. He says they simply do not go bad, ever. He wouldn't even agree to look at mine. Just told me to troubleshoot.

I am looking at one on ebay, will buy it then send this one to him so he can see a bad one for himself.
