Improve the performance of your fuel injected Chevrolet by installing our high dwell Dyna-Module! Dwell within the module controls a coils saturation time, which is the time needed by the coil to produce a spark. The dwell in our 7 Pin Dyna-Module has been increased electronically to provide the coil with additional saturation time. The result is a more intense and longer duration spark in the combustion chamber that will improve throttle response and low end power! Installation is easy as the Dyna-Module mounts in the original factory location with no modifications.
Fits 81 – 90 GM Computer Controlled V8 Distributors with coil in cap.
