Let's say we've got an engine that runs best with 30 degrees total advance at 3000 RPM. Further, let's say this engine is running high compression and pings badly at 1500 RPM under a load. We determine the timing profile using a dial-back light and discover that we're advanced 15 degrees at 1500 RPM. After a few tests, we find the pinging at 1500 RPM can be completely eliminated by backing off the timing 2 degrees at the ignition plate. The problem is, now the timing is retarded 2 degrees throughout the entire RPM range. That means maximum advance is only 28 degrees at 3000 RPM, hence the top-end performance is degraded slightly. Clearly, we need to be able to alter the timing slope to avoid this sort of dilemma.For the sake of simplicity in this example, let's assume that the timing slope in the first situation was linear and added 1 degree of advance per 100 RPM.

(OUR CDI Units are not restricted to linear slopes, nor do all timing slopes typically begin advancing immediately from zero RPM, but let's just avoid that complexity here.)

What if we set the ignition plate back where it was, and alter the advance slope to add 1 degree of advance per 115 RPM? (A less "steep" advance slope.) With older mechanical advance units we would do this using lighter weights, heavier springs, or some combination. With modern CDI,s we simply program the CDI to to do it based on specs of the engine. Our programmable CDI units allow us to adjust the timing advance at *every* RPM.

You have to understand the manufacturer's perspective. One product that can be configured to work with a variety of applications is cheaper to produce than hundreds of products designed specifically for one of many applications.
