I took the opportunity to take my tahoe on a longer trip. I had to drive to the south of Germany. It was about 200mls, a forth of it through some small towns and country roads, the rest a longer stretch of our autobahn. I set the cruise to 70mls/h and watched the AFM working. It only kicked in when the road went downward (very little was enough to get V4 mode) .As soon as the road was flat I was back to V8 mode. Without the cruise it felt that the slightest movement of the throttle and I was back in V8 mode. I think there is room for some refinements so that the V4 mode is kept longer even with a little throttle applied.
From the exhaust noise and vibration side all was ok. With the V4 mode at higher revs there are small vibrations but nothing big. V4 mode at lower revs changes the things a bit, more vibartions and a strange exhaust tone.
The overall fuel consumption was 13,7mpg which is what I think very high for that very careful right foot.
what could be done to get better milage out of a e38 controlled LMG 5.3?
Is there a way to get a kind of lean cruise mode? Could I tweak the calibration to get more miles out of a gallon?
I've got my laptop and the EFI V2 with me... what logs could be interesting on the way back to get a close look what causes my engine to drink that much?
