Thank you for your response. What would the procedure be for owners in the US if there was a technical issue requiring service? Would one still need to send the unit overseas?

I usually try to see if the issue can be worked around first to avoid the nuissance. For example, with the Enhanced MS3, if the MAP sensor breaks, you can change a jumper inside the ECU and use an external MAP sensor.

I have also guided owners who have damaged the board by short circuiting, on how to repair the board to avoid shipping it back.

These repairs may not always be possible, but in my opinion it's always something worth trying.
