What are you trying to control? For my Zetec setup I needed to create the extra circuits for PWM idle valve and for the second ignition output. I bought an MS3 kit and soldered it myself. I skipped on the MS3x board to save $100.
If you get a ready-made MS3 with the MS3x board, the extra outputs on there will enable you to drive the PWM idle. As for ignition, you'll be able to use a sequential coil-on plug ignition setup with some VAG coils.
