AMP Drive-By-Wire Controller

Add modern electronic throttle (e-throttle) to your build with smooth control, flexible tuning, and safety-first logic. The AMP EFI DBW Controller closes the loop between your pedal and throttle body for crisp response, stable idle, and predictable drivability.

Why Tuners Choose This Controller

• Closed loop control with redundancy – Monitors dual pedal and dual TPS channels with plausibility checks, major/minor fault handling, and dedicated fault lamp output. Flash codes and bitfield status simplify troubleshooting.

• Seamless CAN integration – Default 500 kbit/s, switchable 120 Ω termination, 11-bit messaging, plus 29-bit (MSCAN) passthrough for MegaSquirt tuning. MS3Pro users can enable Real Time Data Broadcasting for plug-and-play RPM, gear, and idle inputs.

• Customizable throttle mapping – Shape pedal feel with the Throttle Follower curve and apply RPM- or gear-based limits to manage torque.

• Built-in throttle blip – Supports rev matching during downshifts, triggered by brake/clutch timing windows, delays, and duration.

• Installer-friendly calibration – Simple two-step process (pedal sweep and throttle sweep) performed with engine off. Interrupted calibrations clear automatically for safety.

• Engine-bay ready – Gasket-sealed, water-resistant plastic enclosure with sealed connectors. Can be mounted inside the cabin or engine bay (away from direct exhaust heat).

I/O at a Glance (26-pin Connector)

• Motor Drive: Motor Out +, Motor Out -

• Dual TPS: TPS1, TPS2

• Dual Pedal Inputs: PPS1, PPS2 

• Inputs: Brake, Clutch, Frequency In 1 & 2

• Analog TPS Output: Isolated TPS output connects to ECU 5v and sensor GND for a stable simulated analog TPS signal. 

• CanBus: CAN H, CAN L, onboard 120 Ω terminator switch

Compatibility & Integration

• MS3Pro / MegaSquirt:

  • Select MS3Pro in predefined inbound messaging and enable CAN Real Time Data Broadcasting

  • Supports 29-bit MSCAN for passthrough tuning (MSCAN ID default = 8).

• Standard CAN (11-bit):

  • Outbound IDs (256–259) transmit pedal/TPS values, voltages, motor current, and fault data.

• Special throttle bodies: Supports Ford Half Scale TPS (0–50% & 0–100% dual-channel).

Setup, Tuning & Features

• Software: Configure and log with TunerStudio; analyze with MegaLogViewer.

• RPM Source: CANbus RPM or PWM/Frequency input.

• TPS Output Range: configurable (full range or exclude idle).

• Idle Control: Fixed throttle minimum, PWM output, or external CAN input.

• Fault Response: Configurable max position under minor fault, deviation/time thresholds, dedicated fault output. Major faults enforce safety limits.

• Throttle Blip: Brake-triggered with customizable delay, clutch window, duration, and % adder.

CAN Settings (Default & Options)

• Baud rate: 500 kbit/s (default)

• Termination: Onboard 120 Ω (enable only at bus ends)

• 11-bit/29-bit: Standard messaging or MSCAN passthrough

• Polling interval: Adjustable for 11-bit polling

What’s Included

• DBW Controller with integrated 26-pin sealed connector

• DBW wiring harness with labeled flying leads (when purchased as package)
