912ULS oil pressure sender

[climberrn]

I have a 912 that's getting a HDX panel. I can't find a setting in the Dynon for the VDO oil pressure sender. All the senders I have tried in the settings read a resting PSI of 8-10 PSI. Looking to buy a new sender to work with the EFIS. I just have a single lead to it now, but can run the + and ground to a new one if needed.

Suggestions on what one to buy?

Most VDO senders can be purchased with 2 posts so you can hook a ground to one side and the + to the other (does not make any difference which side is + or ground, on a 2 post). JEGS or Earls Servi Shop , racing parts on line has them. The range is listed on the fitting nut as the number of atmosphere's ie BAR's

Are they standard 1/8 pipe thread or did Rotax use metric? I have a single post now but can pull wires easily. Just want to make sure it’s compatible with the HDX since I don’t see VDO listed in the menu

Found a Rotax document that mentions the 2 thread types used. Took a few hours searching
