Seems sensor is not very precise at low pressure?

How high does this sensor go? If it's a GDI sensor, I'd expect at least 200 bar, so 0.05 bar resolution isn't terrible. 200/0.05 is 12 bits.

dron0gus · 2022-08-16T19:45:54Z

Actual resolution seems 1/10 Atm
See

rusefi-hardware/SENT-box/firmware/sent.cpp

Line 458 in fc7550c

int32_t gm_GetPressure(uint32_t n)

But we can get 0.05 by averaging two signals.

Hi,
Can you share the code you use in the Blue Pill to test ? i looking to make a similar test on a Audi and a Renault intake pressure/temp sensor that use SENT protocol too with 12 bits data (12 bits for pressure and 12 bits for temp).
Thanks

rusefillc · 2024-05-07T23:49:40Z

@floods57 all the code is at https://github.com/rusefi/rusefi-hardware/tree/main/SENT-box/firmware

dron0gus · 2024-05-08T07:29:30Z

@floods57 can you share partnumber(s) of these sensors?

floods57 · 2024-05-08T11:12:34Z

Thanks a lot ;)
About the partnumbers yes, the Renault sensor is a Sensata 82MPP12-01, the Audi, i have 2, the 1st is a Sensata 04E906051J (82MPP07-03) and the second is a Valeo 04E906051H, the 2 sensor are on the 1.5 TSI, one is the MAP, and the second is before throttle body (boost sensor), i don't know why they use 2 different brand, but many chance there give the exact same data.

dron0gus · 2024-05-08T20:58:05Z

@floods57 thanks for partnumbers.
Second one from Audi is 10 times cheaper then first. At least for used one. Bought two for price of 3 cups of coffee.
If you know other sensors with SENT - please let me know.
Also please note that most recent driver is in main RusEFI codebase: https://github.com/rusefi/rusefi/tree/master/firmware/hw_layer/drivers/sent

floods57 · 2024-05-08T23:07:23Z

Ok, but i am not sure about the code i must use, i looking for the same as in this video : https://www.youtube.com/watch?v=S2xH2oOEYL8 i looking to do a similar testing with a Blue Pill to 1st find the value of the sensor.
Ok about other sensor, i think i can find more, i know there is a other reference for the Renault 1.3 liter, must check, will let you know, at this time i have this 3 in stock for testing ;)
Thanks

dron0gus · 2024-05-13T14:57:55Z

@floods57 for bluepill use https://github.com/rusefi/rusefi-hardware/tree/main/SENT-box/firmware code. But check main RusEFI FW for possible updates, changes.
BTW, do you have pinout for these map/iat sensor? Just received one for testing.

dron0gus · 2024-05-13T21:52:46Z

04E906051H
Room temperature (a bit hot), sea level atm preasure.
Seems Sig0 is pressure, Sig1 is temperature.
Slow channels does not change (partnumber? serial number?) Can we use it for sensor identification?

Pinout:
1 - SENT
2 - ground
3 - power (5V)

only: a note

floods57 · 2024-05-15T11:01:24Z

Ok, Thanks i will try it ;)
For the pinout, i have it for the Sensata 82MPP12-01 (pin 1 is signal output, 2 is GND and 3 is +5V)

floods57 · 2024-05-15T11:07:01Z

Pinout: 1 - SENT 2 - ground 3 - power (5V)

Ok, so many chance that the 04E906051J use the same pinout, will try it, look really difficult to get any information for this sensor.
As i know from the 82MPP12-01, the slow channel is not used, and 1st data (3 nibbles after the status) is the pressure and next the temp, and i just don't understand how the status work on this.

floods57 · 2024-05-16T11:06:33Z

@dron0gus By the way, did you use a RC filter ? Thanks

dron0gus · 2024-05-16T11:49:31Z

@floods57 do you mean input RC filter? No, I'm debuging on MRE board and using analog input with filter C removed. So signal path is OpAmp with K = 1 -> 1/2 divider -> STM32 pin.
Actually maybe because of this I see about 2% of error frames.
