To be honest, I wouldn't base anything on MS. It is fundamentally flawed (from an architecture perspective) and the two old gits who govern the project don't seem remotely interested in taking it into the 21st century. If it wasn't for the community hacking it to pieces it wouldn't be anywhere now.

Don't misread this as "flawed and doesn't work" - it works fine, very well infact, and better than the majority of aftermarket ECU's! But it's only where it is today because of a few dedicated people patching up the bruises.
