Engine was able to run for a sec, so I think the DME firmware programming is ok. Can't imagine engine can fire up with corrupted codes/data DME.

I flashed an MSS54HP with the CSL software

Is it your original DME or a spare S54HP? To narrow down if it's hardware or firmware issue, I would install the stock DME back to test.

Fires on one cylinder and dies sounds like what I experienced when having EWS delete issues.

Unresponsive to software/programming tools and a maxed out temp gauge sounds like it is stuck in program mode. At least that is what I experienced.

He has not responded, so maybe he sorted it out.
