Ignition system preferences

[james schaechter]

I really like the Msd digital 7 units. They take a lot of volts, they have many built in features that older analog and the Msd grid adds on as extra cost .

I have purchased several of them from racers that sold them when going to a grid. Had a few tell me they wished they had not switched to the grid as well.

In any case,I have used Msd digital 7 units on several cars since 2006. I have never purchased one new. Never had one fail,
