The 6LS ignition controller from MSD 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 an aluminum small block without the headaches of wiring a modern EFI system. The controller allows 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, and fits with matching factory connectors for a direct installation. Only a handful of connections are required, including the coils, crank sensor, MAP sensor, and cam sensor. You’ll have your carbed LSX running in no time!
