I think IAC is less of a concern with MS-II - the trigger is the bigger problem. I have time and time again, asked about the possibility of someone knowing the code to write up the decoding routines to no avail. It holds a lot of promise, but at this point we're too small to be counted (they have the router board running CAN to worry about). The way I see it, with the MS-I CPU, if someone know enough HC08 assembly, one could technically hack out a piece of code to decode the RS crank wheel (6 teeth) with the help of the cam wheel (3 teeth in between Cyl #1 and Cyl #3). I knew the logic - I just wasn't confident and comfortable with the code to modify the existing code without breaking it (Not to mention the fact that I don't have a board myself - my car is my daily driver). Do you know how the other EJ crank wheel is like in relation to the cam wheel? All I knew is that it has way more teeth, a short break and a long break. Information is the key - and I believe for the EJs there are really 2 kinds of crank wheel we're dealing with. The price sure beats the hell out of major EM products with lots of functionality, but only if we could get the basics down for running it on a EJ motor
