The demands for better emissions and fuel economy in the mid 1970s necessitated leaner fuel mixtures. These leaner mixtures required greater voltage and more spark to ignite. This challenge led GM ...

In the timing section of "Power Tuning" we learned why a distributor has an ignition curve and how it works. Now we're going to look at the procedure for setting up an ignition curve or modifying an ...

Back in the day, point-triggered ignition system tune-ups were routine and happened roughly every 12,000 miles, along with a set of spark plugs and an ignition timing adjustment. These days, we’re so ...

We can hear the howling already. "Why do I want to put some junk GM ignition on my (insert AMC, Mopar, or Ford)?" The answer is: Don't—unless you like the idea of a higher-performance, more-efficient ...

In 2019, we took a look at an interesting new advanced ignition system from Transient Plasma Systems. It replaces the conventional spark plugs in a vehicle's engine with an ignition module that uses ...
