Msd Multi Spark And Coil

[skidoo_j]

Anyone running the MSD 6al or the coil? Improvements? Mileage go up or down? what was involved in the install? What else had to be replaced?

There was a post about this sometime last year, I think people where saying not to get it, because the 4.0 is fuel injected and there would not much if any noticeable change.

I've read through all prior posts on cc.com Two of the prior forums were single post discussions and the third seemed rather split that if you got it for nothing it's an improvement, but not worth getting new.

 

 

I guess the question i have is people say the stock ignition is very similar and is more than adequate, however if the msd is a triple ign during each cycle under 3k rpm I'd think it would have more complete burn vs stock if the pulse widths are the same. It just depends as people posted if it made any significant difference.

 

I'm not about to run out an buy one. Just looking for people with direct experience rather than hearse. I only want experience from renix era systems too on the 4.0. My uncle runs a msd on his camero and It made a huge difference, but again we have a computer controlled ignitions.

is his camero fuel injected or carb?

 

edit, just re read your post, the MSD was more for pre computer controlled ignition systems
