Here is a summary of what I expect to show on my Westy computer.

Computer is on when ECU is powered
Oxygen sensor reading in volts
Fuel pump ON.
Air flow in volts
Air inlet Temperature (Temp.I)  in volts
Liquid cooler (Temp II) in volts
Throttle Switch status
Injector pulse rate (pulse/second)
Coil pulse rate ( pulse/second) ( and RPM with 100 RPM resolution)
Motor running hours ( Cumulative)
Total injector pulses (resetable)
Four of the above items will able to be showned on the same screen display

My wishing list ( Not sure I will able to do it)
Gas mileage calculation - real time and average.  ( 20000 injector pulses are equivalent to 1 liter )
Liters used after fill up ( resetable)
Temperature sensor reading showned in Celsius
Air flow in percent ( linear to volts reading)
Alarm if one sensor is out of range

  Hi everybody

  So nice to have the West back on road and ready for spring/summer season.

  I am working on a small computer showing the status of all inputs coming from the injection sytem for a 86-91 Westy. (similar to a Digitool). In top of all the monitoring the Digitool can do, do you have any idea what could be nice to get displayed on a small computer?

  I will list soon what I expect to get on my small computer.
