Does the 05 model has a newer system? Does it help the acceleration?
Quote from Acura 05 MDX website.
quote:
The MDX features an innovative drive-by-wire throttle system with technology gleaned from the NSX sports car. This second generation drive-by-wire system replaces a conventional throttle cable arrangement with an all-electronic system that senses the throttle pedal position and relays that information to a computer. The computer then performs the actual throttle activation instantaneously. Unlike the NSX system, this system utilizes a DC motor instead of a Step Motor within the throttle body.
The MDX drive-by-wire system works by means of a throttle pedal sensor, a throttle angle sensor, an electronic control unit and a DC motor to control throttle opening and provide fail-safe throttle operation. This system allows for throttle control to be integrated into the VSA and VTM-4 systems and also incorporates the cruise control function. To improve shifting smoothness, the drive-by-wire system controls the throttle during transmission shifts. To maximize driving feel, throttle pedal characteristics are calibrated to be smooth and linear during start up, when driving on ice or other low traction surfaces, and more responsive during acceleration

| Sure feels more responsive from my 03 MDX. Brakes are better thats for sure. Shift points are WAY better as from my 03 ! Leather seats seem thicker than previous year models ! |

| I think the 04 is drive-by-wire too. But that's not why I'm writing. Slightly different issue... I just want to know if the DC motor technology has improved so much in the past few years or decade that they decided to use this DC motor instead of a stepper motor to control it?! ie. Is a new DC motor (at component level) this precise these days? |
