I'm using an MS3X (Megasquirt) It has full sequential fuel and spark. The throttle body is an Ebay special. The only bad thing is it's imported from China and the seller has zero information on what sensors it uses. I had to figure that out on my own, which wasn't that bad. I think I paid $180 for it. You can buy name brands out there for $500+, which is ridiculous, but I guess you would know what sensors it would accept....
