> Youre definitely right about the sound Adam, its absolutely amazing. I am utilizing a vacuum accumulator, although it is one of the things I wanna improve upon; I believe it is too small. But of course, if its built too big, the signal is dampened too much. Another issue with using MAP is the lack of resolution in the signal, ie: going from idle vacuum to atmospheric with just a throttle blip. This is where a lot of people are steering toward alpha-n. Again, a hybrid of the 2 fueling schemes would be ideal, but with the SDS it has to be a compromise between one or the other.

MegaSquirt has hybrid alpha-n 🙂
