“I think the Safety Car obviously was not ideal for us and it might be that the retirement is in some regards also down to the Safety Car. It is a shame,” added the German.

Joe, Sunny will eventually find the same articles with the quotes from Vettel and Marko that CLEARLY state they suspected the yellow caused the car to overheat. My quote was from Stuck himself. Cut and pasted. Not my words.

However Stuck warned “Herr Vettel” to use his head before making comments that could be seen as “unsportsmanlike conduct” and get him and Red Bull in trouble with the FIA.

“Sebastian Vettel should learn to be a good loser,” he told Germany's Yahoo Eurosport. ”It was clear there was debris on the circuit, representing a danger of puncture to the other cars. For that reason, the safety car was justified,” he said.

He also poured cold water on Vettel's claim the safety car period was part of the reason for his car's failure which occurred the lap after the safety car pulled in.

“I don't think driving slowly behind a pace car can be the cause of a failure, otherwise all the other cars would fail also.

McLaren Electronics provides ALL of the ECU's in F1. Programming by any team is easily checked. Off throttle blowing has always created a heating issue for the engine and compartment. The only electrical item providing additional horsepower would be the KERS. Bottom line is that Lotus and Red Bull will need to provide additional cooling to the engine and compartment or risk losing another altenator. In addition the team is set to use an old version of the alternator.

Well the way I understand it at the time things were said or better say the interpretation I gave what was meant was that the FIA was trying/tried/attempted to condition the race results or tried to inject some excitement in the proceedings like is regularly done over in USA racing by introducing a safety car.

Rob, yes off throttle mapping produces additional heat in an engine this because as a general rule an engine running on retarded ignition runs hotter and one requisite of the off throttle mapping was a retarded ignition to reduce to a bare minimum the torque of the engine, we all remember the number of engines lost by Renault while they were perfecting the system, but anyhow the off throttle mapping is something of the past and no longer possible with the new rules although some even those in a position (F1 sites) able to influence others are still trying to instigate that RBR might still be using the system.
The new system being used is engine cylinders switching off/cutting off which is providing a totally different purpose.

Pcxmac, nobody was sending fuel down the exhaust pipes, yes it's those extra gasses (exhaust) that are pushed out (of course heated because of combustion) which used to attribute to the increased down force (throttles kept open when driver is off throttle pedal), the rest of your post I can't make anything out of it.
All the above was due to the of throttle engine mapping which is no longer with us and cannot be used because the rules now say there must be a direct relation between the throttle pedal and the engine throttle butterflies (movement).
What is in use this year involves engine mapping too, but this system is deferent in that, it cuts out/switches off a number of cylinders in firing sequence (the FIA says up to four) it does save fuel, it does cool the engine, it does provide for some sort of lunch control, it does provide for some sort of traction control, but in no way can it help in blowing anything by exhaust gasses.
