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
-

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
