The Stim will not test the 420a decoder. MSII, i dont think there is a way to test it. On MS1 I used to change the crank input to MSNS even though the baord was setup for 420a and bench testing wasnt an issue.
Hook it up to your car with the factory ECU controlling fuel and spark and check that it reads sensors ect and watch it as the car warms up and see that the Intake and coolant slowly raise up in values ect. make sure your RPM is close and check that the clock circuit functions as it should (reset at 255).
