Mercedes-AMG S 63 W221 2006–2013 Throttle Controller — Ultimate9 EVC451

If your Mercedes-AMG S 63 W221 2006–2013 feels doughy off the line and you find yourself burying the pedal just to get moving, that is throttle lag — the delay between your foot and the signal reaching the engine. The Ultimate9 EVC451 removes it.

It plugs in at the accelerator pedal connector on the Mercedes-AMG S 63 W221 2006–2013, and takes about 15 minutes to fit with no permanent modification to the vehicle.

Four driving modes

• Ultimate — nine levels of increased throttle response.
• Economy — softer response for better fuel consumption.
• Automatic — adapts to how you are driving.
• Factory — standard settings, exactly as the car left the factory.

Twenty tuning settings across the four modes, so you can set it once and forget it or change it to suit the drive — towing, sand, traffic, open road.

What it actually does

The EVC changes the torque request sent to the throttle tables in your ECU. The throttle opens sooner for the same pedal travel, which is what removes the dead spot. It does not remap the engine, does not add power, and Factory mode puts everything back to standard whenever you want it.

Free faceplate in your choice of colour

Every EVC comes with a white interface as standard. Choose any faceplate colour on this page and we will pack it with your controller free of charge — normally $7.50. Faceplates suit the EVC only; they do not fit the evcX.
