I have read the Visteon ESU 131 ECU from a Volvo S40 1800cc. I want to remove the rear lambda sond and catalytic converter (or just the rear lambda sond). 2 experts tried, but they could not. They work as if it were a Ford, but this does not work. Can someone make it correct?
Attached original file and two files that the experts modified, but they don't work.

It's tested solution. Pass in PM.Thanks for the help !!! But now I have a problem. Galetto does not connect to the ECU after inserting the last file that Ford puts... So I can't write your file. I will have to buy another ECU and program it. When I finish it I will write how it went here.
