Hello, im experiencing momentary lean situation, at low rpm when VVT is activated. Its even more notieceable when engine is cold. Its on 150hp HN software, which from factory using VVT just fot cat heat up. I hoped that coping kfurl/kfprg/kfbkrg+nw maps from some 210/225 vvt file, but did not.
Anyone know which map or function in Funktionsrahmen may i look, to aid the this lean spot (two second after VVT get on, lambda correction fall back to normal)?
The axis in kfurl/kfprg are how far VVT goes? Understand, that 0-3deg is vvt off, and 20-22 is vvt on(as i see in real via datalog), so its kind oposite than is visualised by degrees in kfnw.. maps,correct?

Of course i try to search in multiple NWS modules in FR , but see no map for any "enrichment" or something to have influence on fuelling. But i just translating the text. Can be slightly more specific, please?

Maybe, i can imagine, its something like delay between real cam angle and then value used from kf.... maps?
