A few years ago, I helped a co-worker with a supercharged air cooled VW. We initially used the '7730 with limited success. The Megasquirt system seemed more capable of dealing with the "One Off" nature of a supercharged air cooled VW. Shortly after we got the engine running with Megasquirt, my co-worker relocated to the east coast. I don't have any information on the progress of the project since he moved.

If I were to build a turbocharged air cooled VW engine today, I would use a Megasquirt system.
