The LS ignition controllers are perfect for the enthusiast that wants to build a carbureted equipped LS engine. This controller allows you to program much more a timing tape. Additional features include a launch rev limiter (2-step) to get you off the line, max rev limiter for the top end protection and a step retard in case you add a nitrous shot. Best of all, with the Pro-Data+ software there is no need to hire a tuner, the average person can do it with their own laptop. The box plugs into the factory coil harness for a painless installation. The only connections required is the crank sensor, cam sensor, map sensor, and coils.
