1) You have no way to restrict these settings to corner exit. You will have to live with these settings as you go through the gears on the straights for example. 80% throttle providing 50% torque?
2) The engine is not going to burn excess fuel in the combustion chamber and also maintain a low torque output. That means the raw fuel must burn in the exhaust pipes. We have no science indicating this is a net benefit when balanced against the extra fuel load. Fact: a fuel a rate corresponding to 80% does not equate to an engine exhaust output rate corresponding to 80% when at a reduced 50% torque application.
1. No one ever suggested it's limited to corner exits. So, yes, one does have to live with those settings all the time. The part that makes this illegal, however, is that while 80% throttle equates to 50% torque, 100% throttle equates to 100% torque.
2. You answered this yourself in your next post.

Anything else, Capt. Incredulous?

That's incorrect. The curve is well-defined.5.5.6 At any given accelerator pedal position and above 5,000rpm, the driver torque demand map must not have a gradient of less than – (minus) 0.030Nm / rpm.
Perhaps the torque map was not the SUBJECT of the investigation - but rather the catalyst for the investigation?
Yes. I've mentioned that.
In that case you could tune the map just for that situation, stay in a higher gear that you would otherwise, and have it happening only there. The rest of the lap is spent above 14000RPM, and thus one doesn't have to accept much fuel weight penalty.
Just a possibility, I have no info to say this is so.
That's pretty much what I've described. But, thank you for making it clearer.
EDIT: grammar and syntax and I hate my OCD.
