Freeems on 2-stroke ?

I have succesfully built a 3 cyl 2-stroke using a ms3.

Some specs:
6 injectors
Dual fuelpumps
PID controlling wastegate to turbo.
Cop
Maf (frequensy based)

Now my question, is it possible to use freeems doing a simillar setup with a 2-stroke ?

Regards
Anders

Re: Building 3cyl 2-stroke cdi

That looks like a good processor with a lot more omph :-)

Which way is the best route to go regarding buing proto board or just the processor ?

If buing the frescale. Is it less work to hack the FreeEms code then write my own ?

Thank you
Anders
