MSD 6LS Ignition Controller for LS1/LS6 (24 tooth crank trigger) Engines 6010

The 6LS and 6LS-2 Ignition Controllers can now be installed on EFI or carburetor equipped engines. While it may seem blasphemous to some, putting a carburetor on a GM Gen-III V-8 is a great option for those wanting the advantages of the aluminum small block without the headaches of wiring a modern EFI system. The controllers allow you to map a timing advance curve with MSD’s easy-to-use Pro-Data+ software. Other programmable features include a two-step rev limiter, a vacuum advance curve for cruising economy and even a step retard in case you want to add a little nitrous to the mix. The 6LS is designed for LS1/LS6 type engines with a 24-tooth wheel, which can be identified by its black crank sensor connector. The 6LS-2 is designed specifically for the LS2/LS7 and its 58-tooth wheel, which can be easily recognized by its gray crank sensor connector. Both of these compact ignition controllers fit with matching factory connectors for a direct installation. Only a handful of connections are required; the coils, crank sensor, MAP sensor and the cam sensor. You’ll have your carb’ed LSX running in no time!
