Msd Ignition Box

[mrnickleye]

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?? :D

I have never heard of such a thing!!!!I take it the engine sparks normally, with an extra 15 sparks after it?? otherwise it could mess thigns up!!!

What does the Engine management /knock sensors make of if?

Well, now that you ask, it seemed to run good, but I did put a timing light on it a couple of times, and the timing was 'floating' around a bit. Maybe the knock sensor was picking up something and it cause that anomaly. It aslo had a little 'miss' at idle.

Any way, I'm not gonna put it back on. The stock system works fine.
