180 oil psi readings

[JT701]

My Rotax 912s with a Honeywell 956413 started to send crazy readings to the 180 and after reading many blogs this seems to be typical of that sensor when connected to the 912s block. I was going to replace it with a 456180 from Rotax, very expensive, but after rereading Dynons advice about not locating the sensor on the engine I ordered from Lockwood Aviation at their suggestion a less expensive Honeywell which had no number on it but there was a number on the invioce 956415 (which seems to be a Honeywell PX2 series pressure transducer 150psi). The original Rotax 956413 had the wiring connected directly into the transducer so I cut the wire and following the instructions included with the Lockwood sensor to wire it to the new sensor. The black wire from the old sensor had no pin on the new sensor only a 12volt input and white output pin. The was no mention about using the black wire as a ground to anything. The Lockwood kit is a relocation kit to the firewall which isolated the sensor from a ground and the old sensor possible did ground since it was screwed directly to the crank case at the oil pump.This makes me wonder?
The 180 has the 5.4.0 installed with 4 sensor choices. With the engine running choice #(1) 128psi #(2) 128psi #(3) 85psi #(4) 0psi. The odd thing is when the engine is off there are the same readings. With the engine running there is no fluctuation in any reading so it seems that there is a diconnect between the psi and the readings.
Is this a problem that can be solved by loading the newest program into the 180? Can the Dynon progam be loaded with the Linux operating system on my computer? Is this a wiring problem?
Thanks for any help---

RoadStar:

Did Lockwood indicate to you that the oil pressure sensor they sold you was electrically compatible with the previous sensor? If so, it should have just "plugged and played" when set to Sensor Type 4. Of course, that assumes the same wiring is present as in our FlightDEK-D180 Installation Manual (JABIRU AND ROTAX OIL PRESSURE, Page 3-6).

Did you explain to Lockwood that you were obtaining a replacement sensor that would be used with a Dynon EMS?

Thanks Dynon, I contacted Lockwood Aviation and talked to a tech (Aaron) who is knowledgeable about the 180. He said that the Honeywell that they are using (956415) is a direct replacement for the 956413. The wiring is the same so if there is a problem check the wiring. This gave me a place to start so I removed the plug from the sensor and the wiring was correct but on close inspection I noticed that one of the female pins has been pushed back and was not making contact with the male pin, voila the problem solved. In hind sight I should have notice that the oil pressure box that the pressure is shown in was not blinking which would have indicated that that sensor was not powered up, 20/20 hindsight. All is good thanks again for your input.
