Description
The Performance Distributors D.U.I. Dyna-Module 222 replaces aging or unreliable ignition control modules with solid-state technology that delivers consistent spark timing across all RPM ranges. If you’re running a classic GM HEI distributor and experiencing ignition dropout, erratic idle, or hard starting, this module restores the reliability your engine demands. Upgrading to a modern control module eliminates the weak point in your ignition chain and ensures dependable performance whether you’re street driving or on the strip.
