As engine technology changes so does the need for ignition systems and a way to test them. MSD's ignition tester now has the ability to test not only traditional single coil ignition systems but also coil-per-cylinder applications. The 89981 tester even gives you the ability to create an RPM run and let the tester run through the RPM range. This allows you to see the ignition activate any accessories you may be running such as shifters, nitrous solenoids and more.
