I just got the computers back from ESS. Plugged them into the car, and she fired right up!
Runs great. They put the Euro software on there for me.
Good news, I guess, is that if you brick your TCU trying this (for whatever reason - model year, power supply, etc), ESS is likely able to unbrick you.
I don't know how they did it, but I'm assuming they didn't use enthusiast tools. After all, they didn't have my car; they just had the TCU. I'm assuming they have a custom harness they plug directly into the TCU, or they take the TCU apart and flash the chips directly.
