AFR problem K24
AFR problem K24
Hi. Sorry for my english. I was driving one calibration from july to october. In open loop in july AFR was OK over 13. But in october I switched "Use VTC tables upon decel fuel cut" and realised that in open loop my AFR is too lean from 13.6 before vtec to 14.5 after vtec. I tried to add fuel after what AFR changed. But in my cali nothing was changed. Where is problem? Thanks

Re: AFR problem K24
I don't see a problem (apart from the lambda being lean in places). In 'AFR problem.fpdl' the injector is 11.2 ms and AFR 14.5. In 'AFR problem +10% fuel.fpdl' the injector is 12.1 ms and AFR 13.75.

Yes, but if you see datalog "No problems", there INJ 10,6 ms and AFR 13,06. That datalog was recorded in may 2016 with the same fuel tables as in datalogs recorded later in september 2016 "AFR problem" "AFR problem +10% fuel". Maybe there is problem with clearance of my injectors?
