Read the rules. It's impossible and would only work if Red Bull has a second ECU in their cars and can hide it perfectly, though it would be still visible in the data.
Just because there are rules doesn't mean they're being obeyed, particularly in F1.
It is not impossible - point is that it is a software based system, and I claim there isn't a software system that isn't hackable.
As far as the data goes, my point about the "analog" side of things is that you have an electrical circuit with components that can act variably depending on outside parameters. What information is presented to a sensor can be cloaked. A lot can be hidden inside Ohm's Law, and again unless you are an EE you're not likely to fathom the possibilities off hand.
Here's another possibility:
While one is "discharging" the KERS system under accelleration, you could filter the "ripple" of the difference between the torque of the motor and it's rpm, disguise it as a "back-EMF overcharge" protection circuit, and you'd have TC while using KERS. It doesn't show up in the data because if it works right it just looks like the battery reacting to the resistance, or the KERS motor heating up, or any other variables.
The thing is that you have analog components whose operational limits are not binary/digital. You can't measure a capacitor and say that how fast/slow it's discharging relative to the load being placed on it is "normal".
How about this, you could build a capacitor that is placed in such a way in the car that it could be loaded just enough under accelleration G load that it's properties completely change.
Does the FIA pull the battery packs apart? All sorts of things could go on there.
So outside the ECU you've got capacitors, batteries, inductors, possibly diodes, all sorts of things that can be engineered to have just about any kind of reactive property you want. On the ECU side you've got a complex multi-level software application that is not unlike any other software app. Look at the U.S. Stuxnet virus buried in the Siemans control software - there weren't any Iranian engineers that were fooled by that?
Regardless, I'm going to just again say - 2 seconds a lap but only a 10th in qualifying....?
