AMP Engine Management is proud to introduce the MS3Pro Mini, the newest addition to our MS3Pro Wire-In ECU lineup. Don’t let its size fool you — this compact powerhouse fits in the palm of your hand but delivers the same advanced capabilities and build quality that tuners expect from our larger MS3Pro EVO+ HC systems.
Compact Size, Full MS3Pro Power
The MS3Pro Mini was designed for performance builds where space is tight but control is critical. Tailored for engines with up to eight cylinders, it includes:
-
8 saturated injector outputs
-
4 logic-level spark drivers
-
On-board 4-bar MAP sensor
-
Integrated barometric pressure sensor
-
On-board SD card datalogging
-
CAN and RS232 connectivity
All this performance comes in a unit roughly half the price of the MS3Pro EVO+ and MS3Pro EVO+ HC, while retaining the same reliability and processing speed that define the MS3Pro family.
Engine Compatibility
The MS3Pro Mini is engineered to support a wide range of popular performance platforms — right out of the box.
Ideal for:
-
Honda B-, K-, and F-series engines
-
Mazda B6/BP (including VVT) and MZR / Ford Duratec engines
-
Toyota 1JZ / 2JZ
-
BMW M20 / M30 / M50 series engines
-
1–4 cylinder engines (distributor, wasted spark, or coil-on-plug ignition)
-
6–8 cylinder engines (distributor or wasted spark ignition)
-
2-rotor Wankel with leading/trailing ignition outputs
Whether you’re running sequential fuel and ignition on a 4-cylinder or sequential fuel with wasted-spark on a V8, the MS3Pro Mini has the flexibility to match your setup.

8 high-impedance injector outputs (repurpose unused channels as general outputs)
-
4 logic-level ignition outputs
-
1 dedicated fuel-pump control output
-
1 general-purpose PWM output (idle control, boost control, etc.)
-
2 conditioned VR/Hall inputs for cam and crank sensors
-
3 digital inputs (two capable of high-frequency signals such as wheel speed)
-
4 general-purpose analog inputs
-
Dedicated CLT, MAT, and TPS inputs
-
Built-in 1-bar barometric and 4-bar MAP sensors
-
CAN and RS232 connectivity for expansion
AMP Engine Management Innovation
The MS3Pro Mini offers more functionality than the AMP’d MicroSquirt, while remaining similarly compact and affordable. It’s the ideal choice for builders who need full MS3Pro performance in a smaller, lighter package — without sacrificing power, logging, or flexibility.
Whether you’re upgrading from a MicroSquirt or starting your first wire-in project, the MS3Pro Mini is your gateway to advanced, modern engine management.
