Hi I have a problem with lambda shield 2 with original Bosch sensor. The system was working fine but suddenly stops reporting. When I check the serial monitor I receive error code 0x287F (no sensor connected) is there any way to troubleshoot it or is it possible that the sensor is dead? Hi Paul, Ba...

Hello, Currently the new knock setting are lost when we power cycle. How can we save the settings to memory? How are you changing the knock setting? //Define registers and parameters used. #define SPU_SET_PRESCALAR_6MHz 0b01000100 /* 6MHz prescalar with SDO active */ #define SPU_SET_CHANNEL_1 0b1110...

Hello Sebastien, The maximum temperatures can be found in the sensor data sheet . Exhaust gas temperature < 930°C range (operating) Exhaust gas temperature < 1,030°C range (max.) for short time Hexagon temperature < 600°C Wire and protective sleeve < 250°C temperature Connector temperature < 140°C H...

The sensor heats up and all seems happy, but i have no display at all. Hi Dave, I hope you are well! Let's see if we can solve your problem. First, all of the correct files for your shield is available on the Lambda Shield product webpage . I quickly loaded the default ADAFRUIT TEST file into the U...

Hello K6EcuUser, Hi Folks, I'm a bit of a newbie to this, however it does seem that a tach input and rpm scaling would be very useful. So given that the Shield masks or even plugs into the headers (not sure) what soldering is required, could anyone elaborate? thanks. The idea is that you use Arduino...

Hello Anders, Does the Arduino sheild support the Bosch LSU ADV sensors? Currently it is not supported. As I understand it, this is an improvement of the LSU 4.9 and are not only quicker to warm up, but also does not need calibration and maybe even more robust... The performance of LSU 4.9 is equiva...

I've made my own board based on shield 2 schematic. I have problem witch the sensor heating up. Everything works fine for warming up (no errors, calibration) but the programme does not exit the heating loop. The sensor heats up all the time, the Heat LED flashs and the sensor physically heats up. I...

Hello DonP, Thank you for the positive feedback. What purpose will the two additional resistors R10 and R11 on pins 7 and 14 serve? R10 and R11 are just pull-down resistors for the HOLD and TEST pins. I added them for good design practice in the new revision. will the add-on board as can be seen nex...

Hello CMW, According to the informations, Knock Shield is fully compatible with the KS4-P. The question is - how about different sensors? My engine comes from factory with Bosch 0 261 231 144 KS-1-K. Will knock shield do its job properly with those ones too, or the KS4-P are mandatory to go with? Th...
