JPI 350 - Using a VDO Oil Pressure Sender Instead

[jneves]

Thank you Nick looks like I got the right one, they only have one model that is 150 psi two wire. Appreciate the effort to confirm.

Hope so! If you did, please share info!

The part number on a VDO sender is on the "nut" the number in BAR (standard sea level barometric pressure times a number). 5 BAR is aprox 75PSI.
NAPA lists 5 bar as 0 to 80PSI.

They come in either single post; using the case as ground or dual post, where one post goes to ground and the other is used as signal. I've had my best luck using the dual post with a dedicated ground.

That's great info!

I grabbed all the info off the nut today. Don't know what it all means but I hope it will help:

Nut face 1: 0-2 bar
Face 2: 5.19
Face 3: 0-10 bar
Face 4: 32/14

Happy to report I installed the $40 VDO 2 wire oil pressure sensor and it worked perfect right away. fired up the EDM350 and it started looking for new sensor, it recognized the VDO and accepted it as valid. I fired up the engine on the original sensor and it measured just over 80 PSI on the mechanical gauge (cold oil, higher PSI). Shut down right away, moved the oil line over to the VDO, fired her up and there it was 83 PSI on the EDM!

For those that are interested I purchased the VDO 150 PSI (VDO 360430 150 PSI Pressure Sender) from Amazon, current price is $44. see photos below.

Next I'm moving on to Oil Temp, this one I do not thing I will find an alternate so it may just be a JPI sensor. Anyone have input on this one?

Congrats! Let us know if you have any luck with oil temp. I've never seen an alternative to JPI but you never know.

So I have an interesting problem now. After I got my 350 back from JPI for the fuel (J5) upgrade, my oil pressure readings are exactly DOUBLE what they used to be. I used to run 82 PSI at power, now it shows 164. When at idle, I usually showed between 70 and 75, now it shows 140 to 150. I use the JPI oil pressure sender. Has anyone else seen that? What was your fix? I will run a ground just to see if that's the issue and report back.
