The strict regulations that modern cars must adhere to these days mean any enjoyment you can have behind the wheel is quite limited. Unfortunately, the control systems put in place restrain the engine's performance and prevent you from experiencing its full potential. Our electronic throttle controllers are just a small device that can help you restore that exhilarating sensation you’re currently missing out on without illegally interfering with any major componentry.

The factory drive-by-wire system actually dulls down throttle response and, in turn, makes the engine feel as though it's lacking power until a certain throttle percentage is achieved. Even then, specific conditions need to be met for the engine to make peak power. This can become quite frustrating and even unsafe in some circumstances. The Mace throttle controller eliminates this delay that exists between the throttle pedal and the butterfly in the throttle body, re-establishing throttle response and bottom-end acceleration.

In addition to sharper throttle response, our controllers also have an economy mode which basically does the opposite. By powering down the signal to the throttle, the delay in throttle response is magnified. The benefit being improved fuel economy over longer trips and smoother transitions in throttle percentage.

Modes:

  1. Sport Mode: 9 stages of increased accelerator response suited for spirited driving.
  2. Economy Mode: Reduced accelerator response suited for economy driving around towns and on highways.
  3. Normal Mode: Factory throttle response.

Features:

  • OBD.II free, meaning power is sourced directly from the pedal and additional plugs are no longer required.
  • Temperature ranges from -40~+125 °C.
  • Previously set stage numbers are retained thanks to Power off memory function.
  • Improves low torque.
  • Plug and play, Using the same OEM harness.
  • Digital signal output AD/DA up to 10 Bit, efficiently responds to the original throttle signal.

Contents:

  • 1 X Electronic throttle controller

Excellent Overview of Carthage
Format: Hardcover
293 pages of text/maps/b&w figures; 8 pages of color plates; 15 pages of end notes (mostly citations); 20 page Bibliography; 6 page Primary Bibliography; 2 page Acknowledgements; 8 area maps; 1 battle map [Cannae]. This is a well written history of Carthage. It provides a one source overview of the background and history of the city/empire. As a reasonably well read layperson, I am familiar at an overview level with the Punic Wars, Rome, Alexander, and the Alexandrine successor states and this book packaged Carthaginian information very well while adding interesting information that I hadn't come across before. I was somewhat disappointed (hence the 4 star rather than 5 star rating) that there was a very limited drill down to a lower level of detail, particularly from such a noted author. However, this is probably an unfair criticism given the limited amount of archeological information available and the millennia of effort that has been spent in pigeonholing Carthage according to the desired perceptions. I recommend the book highly as a well written overview of Carthage.

Great substance; lousy writing.
Format: Kindle
Reviewing this book is not an easy task. Previously I had very limited knowledge of this period of history. With no background, I found the subject spellbinding. The author has done a wonderful job of gathering, and reconciling, ancient sources of mixed reliability. But, in undertaking that task, the text becomes repetitive, difficult to follow and frankly just plain boring. In addition, the writing style and format detracts substantially from the pleasure of learning from the substance. Everything from run-on sentences with mixed subjects to unclear antecedents, to character confusion because of similarity of names and the author's expectation that one can remember which player is on stage at any given moment. My main criticism of the book is that the downsides could have been avoided by application of the skills of a decent editor who instinctively would have addressed and corrected the confusion in presentation that made it a very difficult read. I hope that a cleaned up edition is prepared and the book released again; I think the effort would be worth the result.

This composer has written an amazing piece of music.
I like how an ancient setting coupled with a new style of composing can produce something so very special. The composer is very creative, and the artists do his work justice. A serious-minded classisist will love this DVD.
