been looking into why my motronic 4.4 for my volvo 960 disables all lambda adaptations on my car when going over 7 in load



basically i have done an engineswap fron na 6cylinder to twinturbo 6cylinder


and also swapped the hfm sensor to one with greater range

now my issue is that when above 2000rpm and partload i get high load +7ms and no lambda adaptation

but when passing 3000rpm i get back to partload adaptation

so my theory is that somewhere in this bin there's a map that defines max load for adaptation or max load that's supposed to be at specific rpm


the hfm sensor should have a range of up to ~1000kg air/hr

and that should be well above the range which i'm at and should be sufficient for atleast some 300bhp

so i think i hit the full load limit and need to change this

any of you have done this ?


i see in motronic 4.4 for 5cylinder na there are max load / rpm and i suppose there should be something similar in the 6cylinder edition


we have overlayed the two bins and have found most settings but not this one

all help is appreciated
