Can you help me with this. I have 2 cars (civic if FA5 k20z3) that already had a very old tuning. I Download the latest update and upload my map .. after this the 2 cars have check engine . AIR / FUEL RATIO (AF) sensor (Sensor1) circuit out of range Hight

AUTO # 1

AUTO # 2

Can you tell me if this is something I can adjust? or is a software problem. If I charge the old map the cars are no longer checked

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?

the problem is that if I put an old map the check ingen no longer appears

Can you post the old and new calibrations?

Here I send the two maps. I really appreciate your help

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?

thanks for your help. Attached here 2 logs

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
