Testing your ignition system has never been easier or more precise. Test both single channel and coil per cylinder ignitions
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.Features:Backlit, large and easy to read displaySettings for 10 different crank types – 1-cyl, 4-cyl, 6-cyl, 6-cyl odd-fire, 8-cyl, 12-cyl, 24x, 58x, 12-1 & 36-1Electronic / Points, and Magnetic Trigger InputsCam Sync Output for testing DIS / EFI systemsEngine speed sweep test modeBattery Voltage displayAdjustable dwell / duty-cycle outputSingle knob controls all functionsCompact designEasy hookupPower Grid adapter harness includedSpark Plug tester included
