Open your skl file in text editor and try to remove all "IAT Compensation" tables. Reopen your skl in SManager. This parameters will be set to default.

:D
I can say more.
If you removed R136 and R138 resistors at the ELD input and input not connected to anything, the voltage at the ELD input would not be constant (It must be set by these resistors). And AFR would not be constant too! AFR will change because of changing voltage at ELD input.

Why you not fixed increasing idle speed for PSP switch too?

Using ELD input as wideband is not a good idea. S300 disable ELD error only, but ELD correction is still working! You can tune maps with wideband at ELD connected, but when you detach wideband from ELD input - AFR will be poor. Use EGR input in JDM ECU. You need just 2 diodes and 3 junction. And it ...

I have this trouble on some ECUs. It leans in closed loop, but in open loop AFR is great. On some ECUs this bug is absent. At b16 engine I just added about 30 points to fuel maps, not percents , to all cells when in closed loop. And AFR was good and not leaning. When I used base map P30 (not hondata...
