Keith I have a Grid controller hooked to an MSD 7al3 and have had it for 2+years.

I had some problems at one time but it was no big deal really as it needed to be sent in for firmware updating. MSD did that for free and covered the shipping back to me.

I don't use it for all the features it has. I was mainly interested in timing control and run recording and that is exactly what I use it for.

I can retard the timing anywhere during a run and was doing that with injection to reduce the chance of spinning the tires.

I also used it to retard the timing for starting when I was running a gas primer plus system along with injection.

It works fine and I replay all my runs usually after a race to look them over and evaluate things. T-Stop racing in particular.....

It's not a data recorder but does give you some feedback and is more accurate than just a replay tach....
