This is what they stated in their email today:

Verified unit had coolant issues. Found the EMS to have a burned 5 volt reference and sensor ground circuit. Repaired damaged circuit and found all sensors to be fully functional. Fully tested all hardware functionality and found all Injectors, Coils, Sensors, High sides, Low sides, IDLES, Analogs, PWS, Cam and Crank, VSS, Relay circuits, and Voltage regulators to be fully functional.
