Early s13 ca18det non lambda car issue

[crispyj]

Hi,

I have checked all the roms for the early s13's. If I understand correctly on fuel maps a value over 128 is a closed loop condition ie looking for a lambda signal.

All the fuel maps have figures in this region, Since these cars dont have a lambda sensor how will they work?

How can I deactivate it.

Thanks in advance

To disable O2 cells in the fuel map, set the values above/equal to 0 and then the 'O' button will turn them off

Raw values shows that these cells are 192 (0) or lower. This is the 'flag' to show the O2 enabled

I'm not sure why the fuel map has those cells with O2 flag if there is no lambda sensor connected / configured in the ECU
