Who is using it and how do you like it? What ignition box is it linked to and what features are you utilizing?

I have quit a few friends of mine that use the 7720 piggy backed to the 7730 and love it.I have it also, and it will be going in w the racepak.I k also see that theres a ton of 7531's for sale because lots of people are doing this upgrade.

make sure you buy a spare

new ones are getting better but we have had 3 bad ones now since they came out.

am i missing something here? imho once again MSD (Mighty Stupid Design) has come up with a product that requires this box, then that box, then this bus strip. now i understand some guys aren't happy unless they have the latest gizmo but when it comes to ignitions the VAST majority of racers don't need this crap and won't utilize 80% of it. holley was ahead of MSD with their packaging but couldn't compete with the giant. MSD finally got a clue went digital and began integrating the basic features an ignition SHOULD have in it. even at that the 15 year old discontinued holley strip ignition has two RPM switches as opposed to the digital 7+ single switch and the holley has the ability to select different (or random) kill patterns for the rev limiters.

now MSD is going back to needing multiple components just to make an engine run?

maybe i'm just a tool but i've never been impressed with how MSD packages their products

I'm pretty sure the grid was made so all classes could use it ( including nhra pro stock )and if you wanted to add the bells and whistles you could just buy the ones you needed.

I personally miss the crane DEC 9000. It had it all and was digital. That with a 7 box was bullet proof and ahead of its time.

The grid plugs right into my v net on the racepak
