Gathering info abt MEx, lurking through forums and here and there docs, spotted that:

Havent spot it here or somewhere on forums, seems interesting, coz forum info still very controversial. Page 10 — makes me

Agreed. But nice diagrams and pretty clear explanation of torque model as well.

I am not sure I understand your concern about this statement.

I am yet to read this to see what the rumble is about, but from what I have seen by scanning it the message is that a badly calibrated control algorithm can go out of its tracks, duuh...

There is one point though, that bothered me for a while now. If there are maps that are meant to be inverses of each other, and for performance reasons they are not calculated on the fly, why does the ECU not check their correspondence (with some reasonable error margin) during initialization, along with the checksums, etc. Not only it would add robustness to the system, it would also eliminate about 30% of posts around here

Despite my criticisms, page 11 has a remarkable diagram.

Love the immediate jump into Bosch world var names as soon as it goes into the enthusiast section! Nice explanation of how the torque controller works though!

I take most issue with the author's comments about whether the brakes can overcome the engine - they're saying that you can't stop the engine and demonstrations are unrealistic because it shifts down to 1st gear and is WOT and at maximum RPM. Any (standard...) car I've come across, it's (standard) brakes would happily stall an engine from max power no matter the gear, it would take a fair amount of brake force I'll admit if it dropped down to 1st/2nd, but by the time the speed is low enough for it to have got it to shift to a lower gear, there would be a fair amount of force being applied by the driver as the engine starts powering up.

For the record I have tested the brakes can't stop the car theory @ WOT on numerous U.S. and Euro models in both the U.S. and on the Autobahn in Germany. Any modern car that I have seen most definitely WILL bring the car to a stop @ WOT regardless of gear including autos that downshift to first gear as the vehicle is slower @ WOT. Those who claim they were unable to stop their vehicle clearly lacked appropriate driving skills to understand placing the trans in neutral or shutting off the ignition will bring the car to a halt much faster. Panic is often the problem.
