Hi dcb,
Am I right saying that you advise climbing the hill with load above 50% of the accelerator pedal and in the sweet spot of BSFC map (low revs, highest gear and relatively high load)? If yes please correct me if I am wrong in the following:
We start climbing the hill as said above, with lets assume 2200 revs and 2/3 load on the pedal. We are in our BSFC sweet spot. Climbing the hill we start to unload the pedal to lets say 50% and our revs are going down to 1800. Theoretically we should loose torque faster than our fuel consumption is dropping. But what is the real world situation. I thing that when we are lightly unloading the pedal/revs are dropping we will have better fuel consumption than staying under constant load even though we are in our sweet spot.
It went kind a long but hope you understand what I mean.
Your or other opinions are highly appreciated.
Cheers
