I have a 7870 Dudu7, Toyota Raise protocol. But it doesn't work. I've installed the update. I'm currently using version V250905. Could this be affecting it?

Mikescotland

KravtLab I'm using the same version.

Water temperature requires velocity to transfer. After filtering, try driving it.

You are still missing a screenshot of the OBD settings interface and a screenshot of the system information. Thank you.

Yes, after the "Speed" data appeared, the temperature was displayed. Thank you.

When changing the "Oil temperature" byte, the "fuel level" in the tank changes. Or vice versa. Is there a way to fix this?

Mikescotland

KravtLab @dudu-lai in Toyota Raise protocol there is an error. Not sure it's in Dudu or raise protocol. Oil temperature and fuel level = same byte.

There should not be any fuel level data in this frame. This frame is from the engine control unit, and the engine and oil temperatures may be in this unit. The fuel level comes from another unit. For example, it may come from the dashboard (daily mileage, total mileage, and similar data).

KravtLab I'm talking about your and mine error -
2e 7d 05 09 D1 D2 D3 D4 CS
D1 changes both, fuel level and oil temperature - it looks it's a Dudu app error. Both values are mapped to the same byte on the UART frame. @dudu-lai

Mikescotland Please provide the canbuslog.txt file (filed within 3 minutes of starting the vehicle).

dudu-lai my mistake. Here is what is happening.
Frame
2E 7D 05 09 0A 00 78 00 CS

D1 - coolant temp 0A - 10° (value - 40)
D2 - 00 as no impact on any metrics in Dudu
D3 - byte that is mismatched in Dudu. The byte conforms to temperature sending (value - 40), however any value here triggers BOTH fuel level and oil temperature in Dudu, it looks like it should be oil temperature but Dudu also takes this value as fuel level. It was also noticed by @KravtLab,
D4 - no impact on any metrics in Dudu.

My understanding is either D2 or D4 should have been fuel level but changing anything here doesn't have any impact on metrics in Dudu.
Unless fuel level is on a complete separate UART address but we've tested a lot and there seems not to be.

Mikescotland
For a better understanding.

Mikescotland привет, вы так и не решили проблему с баком?
ооо, все не актуально, остаток в баке тоже победили. 🙂))

It is possible to add the oil temperature option to the status bar.

How can I display RPM on the navbar or middle status bar of the BYD Sealion 6 Hybrid? Already install OBD ELM that can show RPM and Temp. on DuDU. #dudu-developer
