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...

Re: Read exhaust temperature
Moved to existing thread.Liuyanting wrote: ↑06 Aug 2020 18:47Is there a way to know the exhaust temperature through an oxygen sensor?
If so, how can I read it?

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), ...

best regards 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...
