Ryan, Well, since your referencing my web page I should reply. You need to understand what a dwell meter is measuring first. A dwell meter was made to measure the open and closing of ignition points inside a cars distributer before electronic ignitions came out. This is why you can use it on the DeLorean because you are measuring the opening and closing of the frequency valve. Reading the instructions I state "What you are actually reading is the duty cycle of the Frequency Valve." If you had an occiloscope you could watch the cycle as a square wave pattern. The duty cycle is the length of time the frequency valve is on. In quoting from my Bosch Fuel Injection book, "When the Lambda sensor detects a lean running condition the ECU increases the duty cycle to the frequency valve, thereby increasing the volume of fuel through the injectors." The fact that it says to use the "Four Cylinder Scale" is only a reference to a scale on the meter. It has NOTHING to do with four cylinder engines. If your dwell meter has no scale for four cylinder engines than just adjust the CO to the maximum swing of the needle. Once its adjusted, take the car for a drive and observe the performance. You can adjust the dwell richer or leaner as required. A lean mixture makes the car hard to start when cold.
