Highway Driving Vs City

[002doc]

Hey team, did a long highway drive recently and noticed that at thre start of the trip my R32 GTS-t was using much more fuel then at the end of the trip. Is this because the ECU leans the AFR out as you do more hig way driving in a way of adapting and saving fuel.

Just curious? are the skyline ECU's that adaptive?

Cheers

I think its just the way your fuel guage drops. They're all different. Mine seems to drop more when it's around the E - 3/4 mark. When I fill up it will stay around the F mark for about 100kms or so then start to drop rapidly.

Nope the ECU doesnt 'lean out' on the highway. It will always shoot for 14.7:1 AFR on light loads no matter what the driving conditions.
