What Is the AMP Honda K20/K24 Plug-and-Play ECU Package?

This package combines two things you need for a professional K-Series swap:

  • A motorsports-grade standalone ECU: the MS3Pro MINI
  • A K20/K24-specific plug-and-play engine harness designed around the Honda K24A2

It’s designed for builders who want a cleaner path to standalone engine management without giving up the tuning and expansion capability needed as the build grows.

The harness uses factory-style Honda coil connections, EV6 injector connectors, and supports both cable-operated and drive-by-wire throttle configurations.

Full VTEC + VTC Control

Honda K-Series engines use VTEC and variable cam timing as an important part of their performance strategy. The MS3Pro MINI gives you control of both systems directly through the ECU.

  • Fully user-tunable VTEC control
  • Fully user-tunable VTC control
  • No separate VTEC or VTC controller required
  • Dedicated connections built into the K-Series harness

The harness includes dedicated VTEC and VTC connections at the engine.

Purpose-Built for K-Series Swaps

K-Series swaps rarely use one universal combination of engine, throttle body, chassis, and accessories. This harness was designed around the K24A2, while allowing the flexibility needed for custom swap applications.

  • EV6 injector connectors
  • Factory Honda ignition coil connectors
  • K24-style crank sensor configuration
  • Flexible throttle-body interface
  • Extended ECU lead for flexible mounting

The extended ECU lead allows the ECU to be mounted in a protected location such as the passenger footwell, kick panel, or under the seat depending on the chassis.

K24-Style Crank Sensor

The harness is designed around the K24-style crank-position sensor, Honda 37500-RAA-A01 or equivalent.

K20 engines originally equipped with the K20-style crank sensor require either the K24-style sensor or the appropriate wiring changes.

Premium Harness Engineering (Built to Install Clean)

This isn’t a basic universal harness. It’s designed for durability, serviceability, and a professional finished look—especially important in swap chassis and custom engine bays.

  • TechFlex woven wrap for abrasion resistance and heat protection
  • TXL/GXL automotive-grade wire for harsh engine-bay environments
  • Adhesive-lined heat-shrink joints to seal and protect splices
  • Labeled heat-shrink ends for faster installation and easier troubleshooting

This section can essentially mirror the Coyote page because you’ve confirmed both harnesses use the same construction standard. The Coyote page currently presents these same construction features in this exact section of the page.

Throttle Options: Cable or Drive-by-Wire

Cable Throttle

The K-Series harness supports cable-operated throttle bodies, with the required throttle circuits brought to the supplied throttle connector.

Drive-by-Wire (DBW)

Drive-by-wire applications are supported by pairing the harness with the AMP Drive-By-Wire Controller.

Because K-Series swaps use a wide variety of OEM and aftermarket throttle bodies, the harness intentionally uses a 6-pin DTM throttle connection instead of locking the harness to one specific throttle body. Wire the supplied mating connector to the throttle body used in your build.

The Quick Start Guide specifically identifies the 6-pin throttle connection and explains that the universal interface is used because of the variety of throttle bodies found in K-Series swaps.

What the MS3Pro MINI Adds to Your K-Series Build

Beyond making the engine run, the MS3Pro MINI and K-Series harness are built for tuning and future expansion.

  • Flex fuel support: Dedicated connection for an optional flex-fuel sensor
  • Fuel pressure monitoring: Add an optional pressure sensor for monitoring and ECU strategies
  • Boost control: Connection available for an optional electronic boost-control solenoid
  • Wideband O2: Dedicated harness connection for an aftermarket wideband controller
  • Vehicle speed: Connection for a Hall-effect VSS
  • Connectivity: CAN for compatible displays and expansion devices
  • Expansion I/O: Spare inputs and outputs available for custom functions
  • Tuning: Full TunerStudio registration included

The Quick Start Guide documents the optional flex-fuel, fuel-pressure and boost-control components along with the dedicated wideband, VSS, CAN and spare connections.

Engine & Transmission Compatibility

Platform Supported Notes
Honda K24A2 Yes Reference engine the harness was designed around
Other Honda K-Series combinations Application dependent Compatibility depends on the sensors and engine hardware being used
K20 with K20-style crank sensor Modification required Use K24-style CKP sensor or correctly reconfigure crank sensor wiring
Manual transmission Yes Package designed with manual-transmission swaps in mind

K-Series swaps commonly mix components from different engines, so compatibility depends more on the hardware and sensor configuration being used than the engine code alone.

Know Your K-Series Hardware

Before installation, verify that your engine hardware matches the harness configuration.

  • Injector connectors: EV6
  • Ignition coils: Factory Honda coil connectors
  • Crank sensor: K24-style CKP
  • Throttle: Universal 6-pin DTM connection

The EV6 injector, factory coil, and K24-style crank-sensor configuration are specified in the Quick Start Guide.

Frequently Asked Questions

Does this package control VTEC and VTC?

Yes. The MS3Pro MINI controls both VTEC and VTC, and both are fully user tunable.

Can I run cable throttle or drive-by-wire?

Yes. Cable throttle is supported through the K-Series harness. Drive-by-wire applications can be supported by adding the AMP Drive-By-Wire Controller.

The harness uses a universal 6-pin DTM throttle connection so it can be configured for the specific throttle body used in the swap.

Which K-Series engines are supported?

The harness was designed around the K24A2. Other K-Series engine combinations may be compatible depending on the sensors and engine hardware being used.

What crank sensor does the harness use?

The harness is configured for the K24-style crank-position sensor, Honda 37500-RAA-A01 or equivalent. K20 engines equipped with the K20-style sensor require the K24-style sensor or appropriate wiring changes.

Is the package designed for manual or automatic transmissions?

The K20/K24 package was designed with manual-transmission swaps in mind.

Does the package include a base tune?

Yes. A preconfigured base calibration is stored on the ECU. The supplied calibration is configured for Bosch 52 lb injectors and gasoline and will require tuning changes when the engine combination differs.

Ready for Standalone Control of Your K-Series Swap?

If you’re building a K-Series swap and want a cleaner path to standalone engine management with full VTEC and VTC control, flexible throttle options, and room to grow, this is the complete package built for that job.
