Holley/MSD is pleased to announce the release of MSD Circle Track LS Ignitions. Designed for the increasingly popular LS engine in general and CT525 crate engines in particular, they're compatible with factory connectors and plug directly into the cam sensor, crank sensor, and coils. A GM-supplied preset timing curve and rev-limiter are already pre-programmed into the ignition. For custom applications, just use your laptop to program your own timing curve and rev limiter with MSD's easy-to-use MSD View software. The easiest, most efficient way to control rpm, timing, and all eight coils, the MSD Circle Track LS Ignition is a true plug-in, race-ready component. It comes complete with a full wiring harness and detailed, easy-to-follow instructions. There's even a dedicated port tech officials can easily plug into to be assured that you're playing by the rules, and it auto-detects all coil/cam/crank-sensor combinations – just supply the unit with power and a ground and you're on your way.
