Does it have pn? I mean I have a lot of different noname sensors from eBay and Aliexpress.
But if you know some good quality OEM sensor - I'd better spend some $ buying it.

Ahh I understand, the once I have comes from the development side of a big Swedish car manufacturer ;)
I guess they are pretty expensive, and only markings are Pentronic and a phone number, sorry.

I have discoverred one thing, you can't have a grounding one if you want to measure something conductive that is grounded (exhaust system).
You need a isolated one (the cheap eBay ones I have isn't).
Also EGT are pron to pickup EMI there for I should switch to a shielded one.

Yes, I think Pentronic AB produce good stuff :) Sensor is quite small, looking at your logs it has good response time.
Thanks for hints. Sensors from Ali comes with shielded wires, but I did not check if it isolated. I'll check.

BTW, do you still have issue with LIS2D?

I've not tested LIS2D yet, I'm waiting on my latest board for that. But if I understand it correct it 'should' work.
Where are you located? Maybe I can send one of my spares to you with a bung and everything.

Ok. Let me know if you have some troubles with LIS.
It is not a good idea to send me anything. Couse I'm located in Saint-Petersburg, Russia. But anyway thanks for offering.

I hacked together a display to go in my instrument cluster.
A ESP32 with CAN-Bus and a round gc9a01 display.

is that the 2x24 enclosure how do you superseal with it?

Do you have ESP32 source code on github? :)

Yes it's a 2x24 enclosure and the Superseal don't fit in that case, some butchering is needed :oops:


Sure I can put the code up on github but it's very specific to my car, and I'm sending the can-data via LUA.

I took the Volvo out for a short spinn today. Mostly for testing the Tractioncontrol.
The rearwheels is on auxSpeed1 and front/right is on vehiclespeed (VSS).
Here are some logs:
This one is with the auxSpeedMultiplier set to 0
https://rusefi.com/online/view.php?log=1354
Next one is set to 2
https://rusefi.com/online/view.php?log=1355
This one is also set to 2 and i forced some wheel spinn.
https://rusefi.com/online/view.php?log=1356

I also rerouted the cables for the flex-sensor away from ignition coils, so now flexfuel works.
Although I can't seem to get the fuel temp to work.
