AFR mix adjustment LH 2.4

hello i have just started using tunerpro and oustrich 2.0 to my old Volvo

the reason is that i think modern clear bensin contains more oxygen to burn cleaner and then the old LH dont understand that it need to lean out to get the same AFR as when the car was new.
its no way this car did 15l/100km when it was new at come driving

anyway the problem it when i adjust main fuel map it seems like the ecu want to compensate back to its goal at 14.7

i could turn off the closed loop option but then i could be better out with a carburator!

i have read a bit about this but can not find a fix.
there is a few videos on youtube where it seems like a homemade program do the adjustment of the AFR / Lanbda value but the programs is nowhere to be found

Do anyone have a plugin for tunerpro where its possible to change this?
or a XDF for my Bosch 934 ecu where AFR is included?

thanks a lot

i got a wideband with a narrowband output,
so i was thinking, if i had an output from the ecu to tell the load 0-10v or 4-20ma or others

then it could be feeded in to a small circuit that manipulate the narrow band according to load

do anyone know if its possible to get a output from the calculated load of the engine?
