Re: AIR / FUEL RATIO (AF) ERROR
Can you post the calibrations you are using?
What is the exact year of these vehicles? Where are you located? Have you swapped ECUs?

I'd say the o2 sensor itself has died from vibration, but what do you mean here?dvergara wrote: If I charge the old map the cars are no longer checked

Re: AIR / FUEL RATIO (AF) ERROR
the problem is that if I put an old map the check ingen no longer appears

Re: AIR / FUEL RATIO (AF) ERROR
There's a lot of tuning differences between the calibrations (fuel trim, fuel tables, ignition, cam etc). I suspect that you fuel trims are getting very large with the new calibration and that is causing the error. Can you provide a datalog?

Re: AIR / FUEL RATIO (AF) ERROR
It is running very, very rich. You need to tune the fuel tables. Also the WOT compensation are leaner than 12.5:1 so it is running closed loop the whole time, even WOT.

the oxygen sensor was damaged. Thank you
