Precise ignition timing is essential to produce maximum horsepower. However, one timing setting is not ideal for an engine’s entire rpm range. The dynamics of air and fuel flow into the engine as well as the speed that the piston travels through the combustion stroke all affect the ideal timing setting. Due to these variables, ignition timing has always caused a compromise. The MSD Programmable Ignition accepts no compromises and gives you the ability to program a custom timing curve to match your engine’s requirements!
The Multi-Channel Ignition lets you set an incredibly accurate timing curve throughout the rpm range of the engine. There are three settings that you easily program to create a timing curve for your application. First you set the initial timing, or where the timing will be at an idle or low rpm. Next you set the rpm point to begin the ignition curve followed by the amount you want it to retard (up to 30°) through the high rpm limit. All of the adjustments are made with dip switches built into the ignition.
With MSD you don’t have to compromise your engine’s timing which means more power throughout the entire rpm range!
Rev Control
The Multi-Channel Programmable Ignition features an adjustable Two Step rev control. This gives you the ability to program two rev limits; one to protect the engine from overrev damage and another to activate at the starting line for quick holeshots.
To take advantage of the Holeshot feature, you simply need to install a handlebar mounted momentary switch. When the Holeshot rev limit is activated you can hold the throttle wide open and the MSD Soft Touch rev control circuitry will keep the engine at your desired launch rpm. The limit is adjustable with built-in dip switches and can be set between 3,000 to 6,750 rpm in 250 rpm increments. This way you can concentrate on the green light and, hit it, you release the button and the engine is already at full power and you launch out in front!

Snowmobile Ignition Systems
MSD Powersports Snowmobile ignition systems allow the tuner to easily program in the timing retard start point, rate of retard and the rpm limit using dip switches built-in. Now you'll be able to program in maximum advance for top rpm performance, while retarding automatically at the pre-programmed point, preventing detonation and over-heating. With each kit you'll get the MSD Powersports Multiple Spark Multi-Channel Ignition - the heart of the system, and a lightweight flywheel, high performance coils with mounting brackets, 8.5mm Super Conductor spark plug wires, boots and connectors and complete installation manual.
For a better idea of how it all works, take a look at the kit designed for the Arctic Cat 800/900/1000 Triple. This system consists of the PN 42351 Multi-Channel Ignition (# 1) , 3-wire Super Conductor set (#4), 3 of the high performance single tower coils (#5), trigger pick-up & triggers (#3), and flywheel(#2). Each part is described below.

The Installation Manual you receive with the kit explains how to program the ignition.
Coil Bracket
These convenient brackets bolt to the carb’s mounting studs and hold the bracket securely while keeping them out of the way.
