You're right it's very cool stuff.

I know for fact that a '96 Saab 900s 2.3 turbo had this system. I'm sure later models do to, but I doubt that any of the old longitudinal engine'd 900's ever had even a DIS.

I don't know about Saturn. The latest model Saturn I've worked on is '97, and it had a Delco waste-spark DIS.

Lights, we dont need no stinkin' lights!

...well if Megasquirt makes one available, then it'll be pretty affordable. The benifits would snowball... :righton:

The current SAAB DI pack fits very neatly between the cam box covers on the 95 and 93. It is a single component that drops onto all 4 sparkplugs and has 1 mulitpin plug on one end.

I'll see if I can get a faulty one to cut up and have a look
