It looks like as long as the computer is turned ON there is a very minimal amount of current going to the heater. Usually, about 2.42mA. Can this vary from strip to strip? What is the "normal" value/range here? The strip heater voltage seems to be very minimal as well at 0.07V. The Fuel Sense Voltage is always 0 on my bike, I'm guessing this is for those equipped with a float, but have no idea. I don't understand the Film Sensor Heating percentage. When the fuel strip is being polled this seems to jump to 62.8%. Is this normal? Why wouldn't it hit 100%? Also when the strip is being read, the heater current jumps to 187.76mA and the voltage to 1.05V.

I'm trying to determine what these values are telling me and if they are withing the accepted ranges as I believe my fuel strip is on it's way out again.

Normal ranges (for fuel strip):
Fuel heater current: 0- 300mA
Heater voltage: 0 - 1V
Fuel sense voltage: 0 - 0.5V
Film sensor heating (this is PWM): 0 - 100%
 62% looks normal (100% would be full on). Ultimately it's up to the fuel sense algorithm when and how it heats and measures the fuel level.
This will also vary from strip to strip (that's why there is a calibration procedure).

If your fuel sense voltage is 0V all the time, there is something wrong with the strip (sense circuit is open-circuit?).

No, we can only show what the ZFE reads.

Kobus,

Thanks so much for your response.

I tested the two center leads on the strip. With the multimeter set to 20k ohms it reads 2.55. This tells me the sensor circuit is not open, but indeed the fuel sense voltage is 0V all the time.

kobus:
Please attach an AutoScan of your bike, view the realtime values and then send the logs (Tools->Send Todays logs) so I can double check the fuel sense value for your particular bike.

Thanks
Kobus

deciacco:
Kobus,

I sent two logs, the second one has the real time values in it. Sorry.
See attached for the autoscan.

Thanks!
