Try it, the rear o2 sensor is completely disabled.

Try it, the rear o2 sensor is completely disabled.

After 5-6km Code89 shown. P0141 read by tester. 
put "0000" in line, where P0141 is (0x0E28FC). Now no DTC readed by tester, but Code89 is still shown.

Which programmer is used? My editor cannot automatically detect your firmware file. try to read something else, for example BSL . It is better if it is a programm + calibration.

Hello
I attach reading by boot mode. Only difference at the begin of file.
I just need to turn off rear lambda. Plug is disconnected.
What software can I use to this? Now just try with hex editor.
