Yes, the traditional design is using the MS for 4 primary injectors. Many people are using the v2.2. The v3.0 has tach noise issues and although some people have had luck using an alternate circuit, there is no guarenteed fix. The VR circuit has worked for a few people but not everyone. I am currently working on this but not sure if this is going to pan out or not.
