MSD Digital ignitions

Uncrated · 12-22-2007, 10:13 PM

For "many years" [grin] I have used the MSD 6 AL or MSD 7 AL controllers.

In an effort to become more "modern" I am considering trying a digital controller.

Let me here about your experience/comments.

Thanks

I am also interested in this.

I have been told that the 2-step is a more gentle due on the bottom end. Due to being less random.

I have also been told that the RPM fluctuation on the 2-step is a lot smaller than the traditional box.

Anyone?

Three years ago, I switched from a 6T box to a digital 6 box. Two step rpm is very consistant. Never had any problems with it. The biggest thing I liked about it was it has a adjustable timing retard built into it and a two step as well. No extra modules to plug in or wire. Very clean instalation. Just my 2 cents...

Digital 6 is an awesome box, due to the fact that it has nearly everything you will ever need in the one, small neat package.

If you buy one spend the extra and get the Digital 7 it has quite a bit more in it than the 6. They are a great peice but remember to get the correct coil with it they don't recomend using the pro power from the old 7AL setup. No more RPM modules to keep up with either.

Have a Merry Christmas, Mike

If you have a 6AL or 7AL2 then you can get all of the advanced functions buy purchasing an MSD 8979. This is a fully digital controller that will do everything a Digital 7 does but is only about $450.00. It is used in conjunction with you existing 6 or 7 box (connects at the points and two step plugs in). It runs on the same MSD software as the Digital boxes. It has individual cylinder timing, starting line retard, timing curve, retard for each gear, rev limiters, programable shift light output (which I use to run my auto shifter) and more.
I have been using one for several years with great results. MSD and the aftermarket does not push this box because they want to sell you a new $1100 Digital 7. When I questioned them about this box at the MSD trailer they wanted to know where I found out about this unit. Most of us have a spare 7AL so if you have a failure it means you only have to replace have the system for half the cost. As a matter of fact I priced the 8979 and a new 7AL2 and it was less than the Digital 7. Seems like a better deal for my money!
