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

    Bamboo is an amazing fabric
    Size: Large, Color: Multicoloured I (5-pack)
    Comfy and soft . I’ve never worn boy shorts before so takes adjusting to. Legs roll sliding pants up but easy to adjust and smooth before zipping up then all day comfort. When I wear skirts or shorts they are perfect for that! I use to wear bike pants under skirts that don’t have to anymore. I like that they don’t creep up like regular underwear. I’m a new fan of bamboo fabric and bought briefs in bamboo as well.

    The softest, stretchiest, perfect underwear!
    Size: Large, Color: Multicoloured F (5-pack)
    I have struggled for years to find underwear that didn't ride up. I like bamboo, but had the same problem with them. These Bamboo Cool Boyshorts not only solved my problem, but they are so soft and stretchy that it almost feels sensual pulling them on. They never ride up, roll down, they fit perfectly, and are always super comfortable. I even persuaded my husband to buy the men's version and he loves them too. And I should add, I never write reviews!

    YES!
    Size: Medium, Color: Multicoloured D (5-pack)
    I don't give too many items 5 stars, but these are reorder worthy! I bought these a year ago, and am now going back for another 5 pack; not because my first order wore out, but because they are still SO great, I want more! These are my go to for under dresses, skirts, & flowy pants where I want full coverage, but no panty lines! AND bonus, sweat absorption. The leg openings are a tight when I first put them on, but they stay put and are very comfortable. I get my normal size

    Comfortable but NOT SEAMLESS.
    Size: Medium, Color: Multicoloured C (5-pack), Size: Medium, Color: Multicoloured C (5-pack)
    They are soft and well-made, but they are definitely NOT SEAMLESS, which was my whole point in buying them. There are two cross-seams, as well as a fairly thick hem seam on the legs. If you have a problem with inner thigh or genital chafing, you may want to look at a different brand. Otherwise, these are comfortable and well made. FYI, the ones I received had a matching inner liner, not a white one as some reviewers have noted.

    Buying another package
    Size: Large, Color: Multicoloured D (5-pack)
    Oh my gosh, I love these!!! They are very comfortable and not overly tight. The material is so thin and breathable, very comfortable. Love the colors. Am buying another package! I'm in perimenopause and these definitely keep me cooler than my tradition cotton underwear.
