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
Hi Just wondering what happens if the internal Lambda controller detects a error. On analogue gauge i use closed loop lambda control just on the low load part of the map, because a fault sensor can force the ecu to take too much fuel out. Consequently the engine could run dangerous lean. I'm aware that there is a setting for the alowable control range for closed loop lambda. I'm wondering what the closed loop lambda control will do in case of a error: - if we use the internal lambda controller on the furry or Thunder - if we use a external CAN-Lambda controller? for example does a ALM-CAN transmit all error codes to the ECU? does the closed loop lambda control shut off in this case or are there a chance that the mixture can go lean as on a analogue wideband?
