Currently running Msd 7al3 without crank trigger, has anyone seen any more consistency or performance by going with the 7720 and 7730 over the 7al3? Just see alot of people running them , and was thinking about upgrading myself, but have not had any dealing with them. Door car 582 ci, bracket raced, 5.11 1/8 mile.

Replacing your working 7al3 (I’ll assume the older 7230 model) with a Grid 7720 / 7730 will not make your car any faster.

Many racers that choose programmable ignitions like Grid , do so for the “Versatility” of the features that it offers. Some just add the Grid 7730 control upgrade to their present ignition reducing the cost.

Grid programming is free to download and install in your laptop / desktop. Opening the software and using the Sample.mff file is exactly the same as attaching to Grid. You’re just working in an offline file that can be saved and loaded into Grid.

Here’s something that may help the first time Grid user decide if this is the type of ignition they want to purchase.

Mark, different subject. You posted once on how to simulate all your settings like timing retards and rpm ect on the grid by pushing the TB button to start can you repost that so I can pass it along to my kid.

Thanks
