The RX8 accelerator controller is an APEXi SMART electronic pedal-response unit for Mazda RX8 Series 1 and Series 2. It suits drivers wanting adjustable throttle feel without an engine tune. The supplied harness is included for this 2003-2012 application. It is a reversible, response-focused upgrade. Adjustment remains at the pedal interface while factory ECU calibration is retained.

RX8 Accelerator Controller Features

  • The SMART unit gives in-line control over pedal response without changing the ECU tune.
  • City, sport and track modes provide selectable pedal behaviour for different driving conditions.
  • The supplied throttle controller harness supports fitment across Series 1 and Series 2 RX8 models.
  • Factory ECU calibration remains untouched by adjustment, keeping the change focused on accelerator feel.
  • Finally, adjustable settings can create a more direct pedal character when a sharper response is preferred.

For rotary enthusiasts, the RX8 accelerator controller lets throttle feel suit commuting or more spirited driving. A calmer city mode can make light pedal inputs less eager. Sport and track modes can deliver a more alert character.

The available modes allow the chosen pedal setting to suit the intended journey. This APEXi unit is an RX8 electronic throttle controller that keeps adjustment at the pedal interface rather than altering the engine tune.

Pair it with the AUTOEXE Intake Suction Kit for a broader intake-side refresh, or check the GENUINE MAZDA OEM MAF Sensor when air-measurement maintenance is due. Owners buying an RX8 throttle controller can visit the APEXi official website for brand information.
