Hello, Love the ECU. My car runs better than ever before. Now that I have it tuned relatively close to the AFRs that I want, I would like to turn on the closed loop lambda mode. I have everything set up, but no mater what I do, the CL Lambda Fuel Correction is always 0%, and the AFRs never adjust. Could somebody please point me in the correct direction? I have ensured that all of my lockout values are not causing the CL to run. I have my innovate MTX-L wideband wired up to an external analog input and configured as Lambda 1. Lambda displays properly on inside PCLink, and agrees with my physical AFR gauge. Not sure what else I can check. Any help would be awesome! Thanks! 08-11-2016 GF8.pclr
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?
