<p>Thanks that is my fall back, I will run a lead from my magneto through a 10K ohm resistor to rpm 1 input and see how that goes first. To get your thread back on track I will check the oil px setting for you.</p>

<p>I initially tried an Ebay cheapo Chinese Hall-Effect sensor and they would work great, but I found them to be unstable when heat-soaked. That would result in erratic tach readings if I briefly shut down on a very hot day and then restarted to fly again. Most of the inexpensive senders are not heat-rated. I finally used a genuine <a href="http://www.zenith.aero/forum/topics/honeywell-gt-1-hall-effect-tachometer-sensor" rel="noopener" target="_blank">Honeywell GT-1 gear tooth sensor…</a></p>

<p>Does your VDO sensor have two terminals, one of which is marked "G?" Years ago when I wired my engine, I assumed the "G" was for "Ground" and grounded that terminal and also had zero pressure reading. A quick call to Pete at Jabiru USA and he told me the "G" was for "Gauge," not ground. So, the "G" terminal is the signal terminal and the wire from it goes to your oil pressure input terminal.</p>
