I'm not really sure we can call our MT's a true MT with the DTW, I had a few friends that don't know MT's, drive my car and they all said that mine was the easiest MT to drive (even though they stalled a few times).
The DTW is very quirky and sometimes I hate the extra input the computer likes to give on the accelerator. Haven't stalled accidentally ever though as a result.

To each is his own, but IMO, I think you need to have a car stall in your feel a few times to learn the friction/contact point. If your car is going to compensate a bit, that defeats the purpose of learning it properly.

As I mentioned before, the TSX has been rated as having the best MT. If you need to learn how to drive a MT, you need to drive the TSX (your friends are a testimony of this...they are newbies but found the TSX easiest to drive).

The Drive By Wire system works by replacing the conventional throttle control system. Instead of relying on a mechanical cable that winds from the back of the accelerator pedal, through the vehicle firewall and onto the throttle body, Drive by Wire consists of a sophisticated pedal position sensor that closely tracks the position of the accelerator and sends this information to the Engine Control Module (ECM). This is superior to a cable operated throttle system for the following reasons:
• Drive by Wire greatly reduces the number of moving parts in the throttle system. This means greater accuracy, reduced weight and, theoretically, no service requirements (like oiling and adjusting the throttle-cable).
• The greater accuracy not only improves the driving experience (increased responsiveness and consistent pedal feel regardless of outside temperature or pedal position, but it allows the throttle position to be tied closely into ECU information like fuel pressure, engine temperature and exhaust gas re-circulation. This means improved fuel economy and power delivery as well as reduced exhaust emissions.

still plays with cars
a mechanical throttle cable hooked directly to the throttle plates. The ECM measures parameters such as inlet air temperature, mass air flow, coolant temperature and many others. When the system gets to 150 degrees F, it goes into closed loop and looks at the O2 sensors to optimize AF mixture.
At temps below 150, the ECM uses stored parameters for the mixture.
And the TSX does something similar.
I prefer non-DBW because the throttle response is instantaneous - not delayed by the software in the ECM. Driving my Corvette is much more pleasant than the TSX because of it.

I'm sure there must be better DBW cars out there, but the DBW implementation on the TSX really sucks. It doesn't reduce the amount of mechanical components but actually adds more to it, plus additional electronics to make it terrible. I really hate the way it behaves and it's the main reason I don't drive it anymore.Btw, DBW doesn't have anything to do with outside temp compensation. The IAT sensor monitors that on the intake tube. ECU will then alter fuel/timing accordingly.

way late but 6MT here! Also I agree the DBW on the TSX sucks. I occasionally drive a 2006 328i and it has DBW and it's noticeably better. I wonder if acura improved this technology in the 2G TSX?
