Yes, mine is the latest MSII with the faster processor and ignition support and CAN. There are definitely limitations but for controlling extra enrichment and altering ignition timing I think it will be fine. I will be leaving the stock ECU to take care of the rest of the car so the MS will only need to perform a limited role. I am looking at it as part of an integrated solution, not as a complete replacement for the stock ECU but it will need modifying to do the other things I am looking at. For the price there is nothing to touch it. The best part is that all the development suites are free; with a lot of the other systms you buy the ECU then end up paying a fortune to set it all up.
