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

Perfect replacements for the G30
I wanted to replace the filters in my old G30 more frequently, as it's still running like a champ. I figured keeping up on it more often would help prolong its life expectancy. So far, so good. The less expensive replacement parts definitely help me not get upset every time I want to replace something. All parts from this pack fit perfectly, and the price is reasonable enough to avoid pushing replacements to the very last minute—at least it did for me, lol.

Great product for money but pay attn to your model filters are different on newer models.
Size: 20 PACK
The rollers work great and fit nicely into my Euphy which turned out I have a early version of which means none of the filters don’t fit my Euphy unfortunately and I hadn’t payed attention to the filters I was looking to get a 2 pack of rollers, the filters look nice though like they would make a great seal with the plastic and seal around them. I won’t buy them again for sure though for obvious reasons. Euphy is so much quieter then my second vacuum that’s a Roomba and she definitely gives her a run for her money and when it dies I will definitely be replacing her with a Euphy.
