Happy with your stock LS ignition but miss having two step? Well, MSD now has a complete plug-and-play model that hooks up to all your factory plugs. The module also has their “Smart Launch” technology, which keeps you from activating your two step by accident.
Basically, if you set your launch RPM at 3500 RPM, you have to come under that RPM again before you can activate the two step again. It all hooks up with a simple clutch/trans-brake switch. We'll have to see if these work with LS3 engines, because we could use a 2-step badly on our 2008 Corvette.
