EDM 900/930 Install in a K Model

[pkellercfii]

I'm wondering if anyone has ever installed an EDM 900 or 930 in any K model, powered by any TSIO-360 engine. If so, where is/was the oil temperature instrument installed?

I'm in the process of an EDM-900 install in my '89 K model, which I'd characterize as a factory-vanilla 252. It's powered by a TSIO-360MB engine. I'm stumped on where JPI's 5/8" NPT oil temperature sensor can be installed on the TSIO-360. This oil temperature sensor for the EDM-900/930 is different from what is supplied with JPI supplementary engine monitors and is apparently intended to be installed in a different place. I don't think it will fit in the location where the OEM oil temperature sensor is located, which is at the base of the oil cooler. JPI's tech support has not been helpful on this.

@kortopates  @Aerodon  If anyone on Mooneyspace knows, it's these guys.

I meant to look at my 252 today, IIRC we installed it where the OEM transducer was on or near the oil cooler.  LHS rear of engine.

I'll take a picture tomorrow.

Don't install it anywhere near a vernatherm - they have been known to interfere.

yes, the EDM-900/930 are primary monitors and will replace the OEM mooney oil temp probe. My recollection is the engine type certificate calls out the location utilized.

Here's a picture - oil temp probe mounted on the inboard side of the oil cooler.   Under baffles.

Not easily accessible, but may as well do it right.

Thanks for the replies. The background behind this project is that it's a part of an owner-assisted annual. A few hours after posting this question, the IA I'm working and I had a discussion on this topic, and we reached the same conclusion that Paul Kortopates suggested--it needs to go into the OEM oil temp sender location, IAW the engine type certificate. As mentioned above, that's not an easy location to get at. As sometimes happens in aircraft maintenance, some disassembly required. I spent a good part of my Saturday pulling the baffling piece off the above location, along with the oil cooler. Although pulling the oil cooler was perhaps not completely necessary, pulling the oil cooler wasn't real difficult, and it did make the process easier. Trashed a $10 oil cooler gasket in the process, but Spruce has those in stock, so that's not a big deal.  Picture of the installed JPI oil temp probe, with oil cooler removed, is below.  The screwdriver is pointing at the newly-installed JPI sensor. 

If anyone has to pull an oil temperature sender from around the oil cooler base of a TSIO-360, it appears to be accessible by simply pulling the piece of baffling between the oil cooler and the crankcase. For my engine, that baffling piece was secured by three screws--two at rear, and another at the front. That said, removing the oil cooler as well isn't difficult, it's secured by eight screws at its base. Removing the oil cooler makes the process much easier.
