For what your doing the MS1 will be just fine, you will need a few extra things like a flyback circuit and it will allow you to do what the SFMU does except be a million times better and its cheaper. If your only running 8psi you don't really have to touch the ignition tables which you wouldn't be able to with this ECU but if you did want to you could bump up to the MS extra board and make more power with ignition control....just food for though for those that think MS is too expensive. You don't have to run the MS3x board with all the bells and whistles.
