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.

Great suit, great price
Size: Small, Color: Dark Grey
Had to send back because jacket (small size) was too tight around my upper torso so you could tell it didn't fit right. The pants though were the perfect fit, so much so I contemplated keeping the suit - it looked expensive. The suit was delivered as promised so I am thankful for that. Beause I needed it for a wedding the next day I couldn't wait on this seller as I didn't see them offering an overnight delivery. But kuddos to them though for working with me

great suit for teenagers
Size: Small, Color: Dark Grey, Size: Small, Color: Dark Grey
We loved this suit, it is true to color so it has this high end quality look and fit my tall(5’10), 14yr son like it was custom tailored. he likes that it has a slim fit and still breathable. If only the hidden elastic band was adjustable then this suit would have been perfect. It was great for 8th grade graduation and affordable

Quality fabric is prom quality.
Size: Medium, Color: Navy Blue, Size: Medium, Color: Navy Blue
My son is 170 lbs 5’11 fit like a glove he is normally a 34 waste there was room in the pants didn’t need a belt they sit nicely,very little stretch In the pants and jacket, but for a slim teenager not a problem. and he has a little longer legs than average I’m surprised they were perfect length. Quality fabric it was suit material, the pockets on the jacket are fake that’s fine for me. The color was awesome! This cooper and Nelson men’s suit was $61 delivered to my door, best purchase and affordable. I give 5 stars I’m so happy with it so was he.
