Changing the fuel flow is more than just code. I am not an engineer but I know there are stresses and other things that have to be taken into account when any change is made in an F1 engine. Or any high performance racing engine for that matter. They have been developing these engines for atleast a couple of years and they have to be ready in roughly 10 months.
I didn't word that very well on the aero
Umm, someone said the aero was going to change, and that was going to contribute to the lower lap times. What I was saying is that if you lower power, with all else being the same, you'll not only be slower because of the reduced power, but because the original aero was designed as a package with the power to accommodate the drag and get the desired straight line performance. In other words, if the fuel was unrestricted, they'd be making way over 1000 hp with the new motors. But the cars wouldn't be much if any faster in acceleration because they'd just load up the aero to increase braking and cornering loads, playing that increased drag against the new power.
I'll agree that changing a design in late stage of pre-production can be problematic, but the expected power is so low, they must be anticipating an increase later. I think they'd be pretty foolish to bake in design factors that would just have to be redone for a simple 20-30% power increase. I think it's more likely that the powers that be are pushing the technology - forcing the engine makers to come up with solutions. Politics in other words.
