@zed65 what type of EGT sensor are you using?

A K-Type, I can take a picture if you want.

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?

[zed65]

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.

Note to myself, this is my current pin-out to the ECU

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 have some problem with LIS, see https://github.com/rusefi/rusefi/issues/5928

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

What's going on here?

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

Do you have ESP32 source code on github?

[zed65]

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


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.

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.
