Some experience with the diff temp in the airVentDispaly:
I'm surprised how high the e46 m3 diff temp get. In 80 km/h it is typically around 105 deg C. It takes approx 1h normal driving for the diff temp to stabilize. Pushing a bit steep uphill, and it easily get up to 115 deg C. Remains to see how hot it get at track, but I expect it to be quite hot. It seems like the e46 m3 diffs goes pretty hot compared to other diffs.



Also with my factory new diff, the temperature is pretty high, ~100C at 80 km/h.

My new diff with calibrated temp measurement sensor:

Playing with my airVent Display:





Interesting to see that the e46 m3 diff goes pretty hot. Measured on my old one and on my brand new one, and they both seems to go very hot by design...



Did also some thermal measurements of the diff...


As one can see by the picture below, the surface temperature is a bit higher close to my measurement point (Bx2; 67C) than around the drain plug (Bx1; 61C).

airVent Display: Several months now with the airVent Display in my car. Must "admit" that I'm very pleased with it. My favorite screen is probably the one showing the time series of the difference in the axle wheel speeds, brake bias at last braking, individual wheel speed, brake pressures (not shown in the picture below) as well as the current engine temp and oil temp. Really fun to see which wheel that "locks up" at hard braking, as well as which rear wheel loosing traction...

I'm not sure how to respond on this. This thread is indeed a development blog...

A bit hard to respond to when will "this" be available, since there is no such thing as "this". With so many options and configurations the system is tailor made to each configuration. What is your preferred configuration?

In post 64 I said:

Have received so many requests about price etc...

This project started for fun, without any intentions to sell anything. Based on the feedback and questions, I realize that there exists other enthusiasts which would appreciate similar solutions in their cars. Being a developer both by profession and mind, I'm not convinced that taking this project to a product, involving customer service, installation issues, support etc. etc. is a vice step to take. However, as an attempt to clear my mind and (hopefully) make it clear what to offer, I have made a draft of a Web shop with product description and prices.

With so many options and configurations, it is too hard to answer the general question: "What is the price?" For those interested, please have a look at the Web shop to get a feeling. There is even a coupon code for m3f enthusiasts (coupon code m3f gives 10% discount). Link: airventdisplay.no

Maybe, in a not too distant future, I'll take the full step and open the Web shop, if the interest is still there. Still some development and test remaining. Enjoy...
In post 75 I said:

Thanks for the positive feedback. Plan to have ready some units within Spring 2018, at least the basic version + all options except brake rotor temperatures. The next in-car tests will be focused on the oil pressure and direct reading of the brake pressure sensors on the MK60. Then the temperature in the diff and the gear box temperature.
However, life is life, and due to issues not controlled by me, I had to focus elsewhere. Within Spring 2018 I had units available, but only for my own cars. The in-car tests of the temperatures in the gear box and diff is finalized, but the direct reading of the oil pressure and brake pressures is not. Seems to be quite a job to install the oil pressure sensor and hook up to the MK60 brake pressure sensors. Will test it during winter time though.

Since I would like to do it as perfect as I can, I had to do several iterations of the bezel. The true in-car installation revealed some annoying reflections in the screen from the rear window, and I had to do several time consuming iterations to get it perfect.

Further, the installation has not been plug and play. However, I have managed to get OEM sockets and socket housings such that the installation of the Basic configuration should be plug and play.

I am not going to promise anything, other than it is likely that some configurations will show up in a few cars within Spring 2019.

But you should be warned: Installation of such a system, even in the Basic configuration, can be costly beyond the cost of the system itself...
  • The installation in my car revealed an engine temperature issue, so I ended up replacing the radiator. It was quite easy to see that the radiator outlet temperature was too high. Better now.
  • After last oil change I saw higher oil temperatures, and changed the oil again, but to another brand. Did also realize that my oil cooler was very dirty and clogged, and I tried to clean it. Will probably replace it.
  • The diff temperature readings I'm sure will result in more frequent changes of diff oil, since the e46 m3 diff goes very hot. Have not tested at track yet, but I expect to see temperatures above 130'C...
