ECM Data Parameters:
- ED01 Throttle position (TPS) displayed in percent from 0 to 100.
- ED04 Coolant temperature (COOLANT TP) displayed in degrees Celsius (°C) from -40 to 151.
- ED06 Injector pulse width (MS INJ PW) displayed in milliseconds (mS) from 0 to 100.2.
- ED07 Oxygen sensor voltage (OXY SENSOR) displayed in volts from 0 to 1.14.
- ED08 Spark advance (DEG SPARK) displayed in degrees from 0 to 70, similar to engine timing in degrees.
- ED10 Battery voltage (BATT VOLTS) read in volts from 0 to 25.5.
- ED11 Engine speed (RPM) displayed in RPM from 0 to 6375.
- ED12 Vehicle speed (MPH) displayed in miles per hour from 0 to 159.
- ED16 Knock retard (SPK ANGLE) displayed in degrees of timing pulled out from 0 to 45.
- ED17 Knock sensor activity (OLD PA3) displayed as counts, an arbitrary number that increases from 0 to 9999 according to amount of activity from knock sensor.
- ED18 Oxygen sensor cross counts (CROSS CTS) displayed as number of times O2 sensor crossed reference line each second.
- ED19 Fuel integrator (INT FUEL) displayed in counts from 0 to 255.
