iron_and_torq Posted March 6 Report Share Posted March 6 Good evening! I have been running a Link G4+ PNP on my e36 and have just installed a Powertune Digital Dash. I am now enduring the task of being able to monitor fuel level over CAN. I have done some research and understand most of what I am reading. However, my concern lies with having dual sending units. The resistance ranges from 50-500ohm combined. I found this diagram (attached). My question is, will I have to use different size resistors since my resistance for the sending units is higher?

Adamw Posted March 6 Report Share Posted March 6 You wont need that 10sq050 diode. change the 100ohm pull-up to something like 3-500ohm will do. Quote Link to comment Share on other sites More sharing options...

Ok, I will try that! Will I stick with the 10Kohm resistor still? Assuming to dampen fuel slosh? Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 7 Report Share Posted March 7 The 10K and the 680uF are a low pass filter, "slowing down" and smoothing the signal. Quote Link to comment Share on other sites More sharing options...

I just realized I am using all of my AN Volt pins. I do have an AN Temp left though. Would this be something I could use? Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 10 Report Share Posted March 10 AN Temp inputs can only have temp functions assigned in G4+. Quote Link to comment Share on other sites More sharing options...
