Glen, I will try to help. I went from a 6al to a grid system. IGN and controller with the recommended coil. The car idles better. I was having to change plugs every other month. No more, could go for a couple seasons now.
The features are great. You can change timing during run. Many different ways, you can add a module that allows instant or last minute rpm adjustments. It has built in data recording and also includes a way to interact with racepack. Several shift or shift light activations rpm or time. Many more I’m probably forgetting. I liked it so much I bought 3 systems. 1 for a spare but haven’t needed it
