Perfect, thank you.

I completely agree.

I was thinking the same thing as I was this thread from the beginning.

I have just enough electronic and software background to pull this off. Thanks Ahsai. It's on my long-term project list. I will post back here if I do an LCD implementation.

One more whacky late night thought on this project: could you hack a drain plug with a temp sensor wire through it, and an analog oil temp gauge hanging under the car, for stationary test that would calibrate the in-dash gauge with a direct analog oil temp sensor temporarily kludged under the car? I wouldn't want to test it moving, but a good 20 min warm up in the driveway would allow you to tune the calibration parameters more precisely.

EDIT: never mind. Obviously you calibrate it with the Durametric readout. Duh.

A clean solution would be to use Racecapture for this, really makes sense if you have a phone/tablet in the car as a dash.

It would be "easy" to get oil temp and oil pressure recorded and displayed. It would also be stored so that you could look at the data afterwards, you could then correlate oil pressure to G forces, RPM and such.

Just like Ashai's solution you would "tap" into the analog value of the sensors. It also supports reading CAN values if somehow you can figure out what code that is.

This is an example display, you can customize it:



Here they analyze some data, here they have RPM/SPeed/TPS but you can change to anything. I think G force and Oil pressure would be an interesting combo. And also coolant and oil temps.

We use it on our Miata race car, it's from 2006 so we read all the values from the CAN instead. On my megasquirt datsun race car I have a mix of CAN and analog sensors. Generally the HW is very good but the SW has some kludgyness, but it gets better.
I don't track my 996 that much so haven't bothered with it.

I've done this to all my old ACVW's in the past and have wanted to do the same here but, I want a different location for the sensor.

The ultimate for me would be to replace the volt gauge with an oil temp gauge - like the Carrera GT!

Who needs a volt gauge... facepalm Porsche, faceplam...

I'm looking to do this in the spring time! Thanks for the work and write up.., Would a t-cap connector work in getting the signal from the DME?

Something along the lines of https://cdn.shopify.com/s/files/1/25...ors-Banner.jpg

you guys should get on fixing our water temps gage

all a bit to complex’s for me l think there is a tapping under fuel rail to fit sender as on a 3.2 2000 Boxer Engine . Thanks for reply.

My car came with this mod done using a digital display. While fiddling around with the center stack, the ground lead from the DME came loose. I tried to figure out where to place it on the board based on the basic schematic I got with the car. I’m afraid I may have messed it up as my display reads 8888 regerdless of which pin this ground is connected to. Anyone think they can help me out?

Ahsai,
Just came across this thread. Did you add this to my ('old') 996 or the earlier one?
