#4457, "RE: Question on MS and MSD-DIS" In response to In response to 5
If the MS was built with Spark control, you need to find out if you have internal ignitors or not. The v3.0 board mush have the internal ignitors otherwise you will have noise that causes issues.
V2.2 you can export led17/led19 with a pullup resistor and run it right to the MSD box.
The links posted above should help you but we need to know how your MS is setup and what board you have to give you more detailed explaination.
