Product details
- Type ECU
- Vendor AMP
- SKU AMP-DBW-PKG
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)

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)

Easy to install. This is a great addition to an old-school project where you're not using a full ecu to control the engine(carb setups, factory ecu setups) highly recommend this controller. Great value.
I have been waiting quite a while for a MS3 compatible DBW affordable controller. I set this up on my test bench and easily got it working by following the manual. My application is simplistic. I'm using this on my 1973 F350 / FE which I mega squirted back in 2009-2010. I decided to enhance my setup with the latest new stuff. My application is using a 2007 Mustang GT throttle body and an accelerator pedal from a 2017 F250 SD. It works great, and tracks very smoothly without any annoying buzzing or flutter. I'm happy with it!
As with all AMP EFI products, this DBW controller comes in at a great value, being priced lower than other similar products. It’s built well and the tech support from DIY Auto Tune is great! When I had questions regarding set up of this controller the responses were prompt and helpful. This along with with their MS3 pro mini have made getting my turbo flat six swapped Subaru Legacy a reality.
