Re: Reading temperature of sensor

I did as described above, I swapped out the Rical resistors for know values and converted some of the temperatures to UR values. UR 110 = 888°C UR 174 = 780°C UR 461 = 642°C UR 540 = 628°C UR 868 = 25°C I need to get an 80 Ohm resistor to make it go up to 1000°C accurately. The sensor will always re...

Is there a way to know the exhaust temperature through an oxygen sensor?
If so, how can I read it?
Moved to existing thread.

Re: UR analog value does not change with temperature

Can the pump current and voltage be monitored by reading the registers of the CJ125? Unfortunately not, the later versions of the CJ-series have this but Bosch do not offer these components for DIY projects. If the target for the PID controller can be ramped up gradually (i.e. a controlled sweep), ...

Finally mounted the lambda sensor in the exhaust pipe of the YFM 660R Raptor, AFR gauge and the shield lambda shield.
Great job Wolf! Thank you for sharing your work, hopefully it can inspire someone else. As always I took the liberty to post your pictures and code for long term keeping.

hi christian iam wondering to know in the lambda sheild 2.0 what kinda mosfet are in use are its still the STD30nf06lt4 or difrent kinda mosfet thanks
best regards matthew
Hi Matthew,

Lambda Shield 2 uses the same MOSFET as the original Lambda Shield.

Re: UR analog value does not change with temperature

Hi Scott. My current idea is to increment the heater control in steps. Monitor the current and voltage of the Nernst-cell and by that map the UR ADC value with the temperature based on the table from the Mini LSU datasheet for each point. With that we could generate a lookup table based on the UR va...

Re: UR analog value does not change with temperature

Hi Scott! I am glad to see you found your way to the forum. So I suppose a simple linear equation would give a relatively accurate conversion down to 650C if we had another point of reference. http://www.bylund-automotive.com/support/images/Temperature_1.png The Bosch Technical Product Information Y...

Re: Compatibility of different models of LSU4.9

here it is for 112 € https://www.turboloch.com/Bosch-Lambdasonde-0258017217-LSU-49-Mini Hi Daniel, I am sorry to disappoint you but I think you are mistaken, that is not a Mini LSU 4.9. It is a standard LSU 4.9 for the Mini / Peugeot / Citroen, all using the same PSA engine. Search the part number ...

Re: Compatibility of different models of LSU4.9

I found the Mini Version of the LSU http://www.bosch-motorsport.de/content/downloads/Raceparts/en-GB/52013451208138123.html Hi Daniel, Interesting question. According to the 2015 Bosch Motorsport price list the Mini-LSU 4.9 cost around 3.500 EUR. It is a bit out of the price range for evaluating co...
