There are a decent amount of people running the 420a code with MS2 and dont have any major problems, so there is something wrong somewhere of course.. In this diagram:




Remove and jumper R12, its not needed at all in this input setup.
Replace the "150 ohm" 5v pullup resistor to a 470 ohm.
Make sure C30 is removed as well. This should closely mimic the V2.2 board input circuits, which work perfect.

As for the spark outputs, they are identical to MS1 in respect to the LED mods. I never really cared for the VB921's, so i would really try and use a Mitsu ignitor module- Fire the module from the LED's, and then hook up the module to fire the coil pack. Also, make sure you haven't reversed the ignition outputs, or firing will be 180 degrees off, and it wont run.
