I am looking at this guy's Greddy Emanage ultimate. It looks like a pretty nice piece. To the best of my knowledge it can mess with the MAP sensor signal like the SAFC, but it can also control fuel directly and with some wrangling, spark directly as well too.

It actually costs less then a megasquirt up here too. I remember a guy posting saying he got it running, and that he was working on getting the spark going too, but it was locked because he didn't actually say how to do it. any input?
