Steve Wong is the gentleman that owns and runs 911Chips. http://www.911chips.com/. He is the DME guru. I ordered a completely refurbished DME with his performance chip and literally had it the next day (paid for overnight shipping of course). You can then send your old DME to him, and if it’s repairable, he’ll refund you a $300 core credit.

True, but read through the info on 911Chips site. Gives a good overview of what can go wrong with just age and wear alone. Mine may have had water damage at some point, but many of the soldered connections were just shrinking in cold and expanding once up to temp. Just from age, best we could tell.

That’s a great resource. Wish I’d had it when I was troubleshooting. I wasn’t suggesting the connections had been melted by heat. And it’s just conjecture as to what caused my board to deteriorate, but it was nonetheless “shorting” from poor connectivity. It was also a FL car before I bought it, and never saw cold temps. My issues surfaced only when the weather got cold enough.

In any event, it sounds like you went through all the same checks and balances and narrowed it down to the DME itself. If resources permit, having a refurbished unit sent out, and sending yours back is a pleasantly convenient way to get back behind the wheel. I was frustrated as hell, and it was a huge relief to just get it running perfectly again. If you have the patience and electrical knowledge to tinker with the board itself, more power to you. I lack both those things.

No path-leading intended on my part. Just sharing my experience. I am the last person anyone should take technical advice from. I defer to those with substantially more experience and know-how than me.
