There are side benefits to getting KLAF right, even if you are running a MAF... for example, if your MAF goes tits up while you are driving around
I understand KLAF is a big part of MAFless, but isn't it also used for target throttle calculation? I'm not at my computer so I can't post part of the FR where it goes over this.
EDIT: It seems I was thinking about calculated mass flow at throttle plate. So am I right in assuming KLAF is specific to throttle bodies?
