Has anyone out there installed an MSD Ignition Box on their MKiii N/A???

I hooked one up 2 years ago. I had to use an adaptor for the Tach/injectors to function properly. It works by making the plugs fire 15x instead of once on each power stroke. It will insure that ALL the fuel is burned. I could not tell any improvement, but I did see my MPG increase by 4 on long trips (26 mpg).

I removed it after 1 year because the tach needle would jump around occasionally. I emailed back and forth with the manufacturer trying to figure a way to get it solved. No success.

Any comments?? ;)

well i myself haven't had experience but IJ on sm will most likely answer ur post ;)

dont put it back
msd is garbage
i put one on a mk3 turbo
and no success eithier

id put one on, but it depends on which model your going to put. last time i checked the dis-4 plus was the one to go with for the turbo models. 6a(6al for rev limiter) for non-turbos. i help my friend install one on his honda and it made a hell of a difference.

Yep....model 6A (no rev limiter). I may try it again, as its still mounted in the car. Someone on another forum said something about grounding any wires that weren't used. I don't knpw about that. What do you think?? The MSD tech line guys did not say to do that.

Oppsss....last post was mine...forgot to log in.

when installing one, you may not need the use of the ignitor. all you need is a trigger signal to the box for it to fire the spark. its been a while...
