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.

Notes:

• Electronic throttle controllers for other makes and engines can be purchased through other listings.
• Installation is quite simple and the modification is completely reversible within a couple of minutes. All kits include simple fitting and calibration instructions.

Exclusive to Mace Engineering is our design-registered plenum spacer kit to suit Chevrolet SIDI LLT 3.6L V6 engines.

What is a plenum spacer and what does it do?

A plenum spacer thermally separates the plenum cover and intake manifold. Its main purpose is to improve the air distribution between cylinders by slowing down the air speed inside the plenum chamber. As a result there is less of a pressure drop inside the plenum chamber between cylinders, and less air momentum, resulting in better air distribution and power. The change in airflow characteristics is shown in the diagram below.

Not only will our spacer help you make more power, it will also help prevent any costly rebuilds through dangerous lean outs that occur due to poor air distribution with standard manifolds in high horsepower/boost applications.

In addition to improving air distribution between cylinders, the increase in plenum volume also has a positive effect on bottom end torque.

The fact these spacers are manufactured from the same thermal resistant composite material as our manifold insulators means further horsepower gains are possible due to the reduction in heat soak.

Key Benefits:

• Design registered.
• Reduces charge air temperature resulting in better power consistency and detonation prevention.
• Power increase with no undesirable side effects.
• Improved air distribution between each cylinder.
• Improved fuel economy.
• Easy to install.
• Can be used as a replacement gasket.
• Reusable.
• Proven gains at an affordable price.

Contents:

• 1 X Plenum spacer 
• 1 X Bolt pack (Not included in MI690, refer to parts guide) 
• 1 X Silicone gasket maker
• 4 X Spacer bush
