Yep I have scouting this for a few months! Do you have it yet? How is the colour match of the plastic face? You cant beat the 996 single din mount and flashing alarm presets.

jaykay did you buy that cable direct?

No its a softronic cable. I got it on planet 9, on special. Once I find a good internet connection method, I am going to read my ECU and flash it. I was holding off on this as I wanted to get all my mods in place first but it seems they like a good stock file to work with; the modified file will adapt to the changes that are made after.....counter intuitive to me ....

Hop fully this a few other things will give me enough ooooomph to get past people in my run group when I am able to get back to track driving. In the lower groups up here you have to pass on the straights so you have to be right up on them on a straight....loose momentum and you will have a 944 up your bum as well

i looked on the ecu pinouts posted on pelican (in the engine swap tech article) and they do show an oil temp sensor for the 7.2 ecu. however, it is a 911 diagram and the boxster may not have that sensor (similar to the boxster not having an oil pressure sender - wtf). so, it would be nice to know if there is any truth to the statements i've previously read that the boxster just extrapolates oil temp from water temp or whether there is an actual sensor someplace. it would be nice to use an obd gauge instead of installing a whole new sender and having to wire from the back of the car forward. would have to wire an oil pressure sender regardless, but most of the obd gauges allow for external inputs as well so could accomplish it all with one gauge instead of two.

well, theres part #27 here:

Porsche 996 Oil Pump Parts

called a water temp sensor but located on the oil pump and sold as an oil temp sender by pelican (that's where i got the part number). uncertain if it sends temp reading or just sends on/off at a certain temp (ie, to trigger an idiot light or open a valve to the oil cooler).

#27 screws into the coolant guide manifold & only coolant contacts it. Pelican has many mistakes in the catalog & I assume this is one also, however I have been getting a P0197 code = oil temp sensor & keep ignoring it because it's a pain to replace either of the sensors that might be causing the code.

That might be the one...it was in winter when I last looked into it. the dgauge gives you two externals.

It may be stuck in a water jacket next to an oil gallery....water temp in two different places.....who knows. Trying running your durametric with ECU info tab open and call up engine temp and oil temp. The oil one lags behind but this from cold to 180 while idling....I will have to do one driving.

What should one expect to see for oil temperature? I would think itwould lag like I saw and then overtake water temp.

I have massive 2L deep sump so that may sku the readings for a while anyway

I agree with your "bold" statement & theorize that the harder you load the engine the greater the oil temp over coolant temp rising to maybe 40 degrees differential. Just my working theory though.
