Check it out. I hope you guys change your minds about the buy back.

I thank you for that and suspected as much. There should also be a non-technical "feel-of-the-car" assessment and we continually see how drivers prefer this to the 350Z.

 

There is a dyno at a local meet this weekend here. I have a GS no DSC no TCS with this "explaination" my car should be performing on the dyno at 210whp?

I guess it is possible I test drove a 350z and it really didn't feel any faster, made more noise that's about it.

Still I'm going to take this opportunity to return the car, I might get another in the spring, I have yet to find another car I enjoy more.

 

I think that there is still part of the explanation that it will be problematic.


If the DSC system is completely disabled, this removes the brake functions from the equation, however it does not fully remove the engine management system functions.

The ABS hydraulic unit/control module (HU/CM), or the DSC HU/CM for cars with DSC, determines vehicle speed by comparing the speed of all four wheels. If two are turning and two are stationary, it will still compute a speed but senses that the car is experiencing excessive wheel spin. To protect against engine or catalyst damage:

The engine management system compares the throttle opening, gear selection (determined by engine speed and road speed) charging efficiency and engine coolant temperature to determine the driving condition.

Since the car is under heavy load, in a tall gear (testing is usually performed in third or fourth gear), with a wide throttle position angle (wide open), spark timing is reduced and the fuel mixture is richened to reduce the occurrence of spark knock and to reduce catalytic converter temperatures.

 

Nope - like mdm said, you've got ABS, and the PCM (Powertrain Control Module, Mazdaspeak for the ECU) apparently still uses those sensors for it's decision making process. The car is just too smart for it's own good!
