MSD Digital ignitions

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!
