The FAST E6 digital ignition tester plugs inline on the 6-pin Weatherpak connector of most E6 ignitions and simulates a trigger signal while you monitor ignition operation. Supplied with a load/test plug for coil wire installation at the distributor cap, it provides an accurate digital rev readout to compare with the vehicle tach and can test RPM-activated switches such as nitrous solenoids. The tester measures rev limits to within 5 RPM and includes a tach calibration feature.
