andpdas posted a topic in G4+Hi I'm using Fury and I am controlling LSU4.9 BOSCH lambda sensor with fury internal lambda sensor controller. I have connected the cables completely as same as the instructions in the Online Help. But I'm receiving these errors. Do you have any suggestions? One thing that I'm worried about is, I'm using +14V(A connector pin 5) as the Ignition +12V input(LSU 4.9 pin 4). I read the instructions of the LSU 4.9 and it says. "Power supply H+ nominal 7.5 V" "System supply voltage 10.8 V to 16.5 V" I don't have 12V output in my ECU so I can only use +14V cable or the +8V cable on the A connector of my Fury ECU. Am I doing some thing wrong or any suggestions would be very helpful. Thank you.(^^♪ http://www.bosch-motorsport.de/media/catalog_resources/Lambda_Sensor_LSU_49_Datasheet_51_en_2779147659pdf.pdf
I found that Fury's internal lambda controller reading is always 0.5 AFR leaner than LM-2 LSU4.9 and AEM UEGO LSU4.9. The test used two LSU4.9 sensors for 3 devices, sensors were cross swapped during test, same result, updated Fury fw. to 5.4.3, same result. LM-2 and AEM read consistently 0.1 AFR diff. I also compared LM-2 to several other AEMs(no pictures), very same result. I think LM-2 is something can be trusted. Any suggestion?
