Choose Your Version: EVO+ vs EVO+ HC
Both models share the same EVO+ platform (connectors, sensors, logging, control features, and I/O). The main difference is the type of ignition output. Choose the version that matches your coils and ignition hardware.
| Version | Best For | Spark Output Type | Typical Examples |
|---|---|---|---|
| MS3Pro EVO+ (Logic-Level) | Coils with built-in igniters (“smart coils”) or external ignition modules | Up to 10 logic-level (0–5V) spark outputs | IGN1A smart coils, many OEM COPs (GM LS, Toyota 1ZZ, VAG COP), external ignition modules |
| MS3Pro EVO+ HC (High Current) | “Dumb coils” that need the ECU to supply coil current (direct drive) | 8 high current (direct-drive) spark outputs | Coils without built-in igniters; direct-drive setups that would otherwise require external igniters |

Ignition Outputs Explained (Smart Coils vs Dumb Coils)
Logic-Level Spark Outputs (EVO+)
The EVO+ model provides a clean 0–5V logic-level spark signal designed for smart coils (coils with built-in igniters) or external ignition modules. Logic outputs deliver precise control without generating high ECU heat, making them a strong fit for modern COP conversions and common OEM smart-coil setups.
High Current Spark Outputs (EVO+ HC)
The EVO+ HC model includes built-in ignition drivers (“direct drive” / high current spark outputs) for dumb coils that do not have integrated igniters. This eliminates the need for external igniters and lets the ECU directly manage coil current for strong, consistent spark.
Inputs & Outputs (I/O) Configuration
The EVO+ platform is built for complex motorsports wiring: lots of sensor inputs, plenty of PWM and digital outputs, and the ability to support serious multi-cylinder and multi-function setups.
- Injector & spark: up to 12 sequential high-impedance injector outputs; ignition outputs depend on model (EVO+ vs EVO+ HC)
- Outputs: 7 digital outputs + 8 PWM outputs
- Inputs: 12 analog + 12 digital + 5 speed + 2 knock inputs
Specialized Features for Enhanced Control
This is where the EVO+ platform becomes a true competition ECU—table-based control strategies you can actually tune, validate, and repeat.
- Boost control: open/closed-loop, boost by gear/speed, switchable high/low tables, single solenoid or dome control
- Traction control: Perfect Run, RPM control, and VSS % slip strategies
- Launch / trans brake / bump box: advanced launch strategies for racing applications
- Nitrous: staged/progressive control for wet or dry setups
- Three-step rev limiter: burnout, launch, and redline limiters (with line-lock and flat shift options)
- Speed limiter: pit-speed and roll-race limiters
- Flex fuel: blending for fuel, spark, boost, and enrichment based on ethanol content
- Water/meth: load + RPM-based variable injection control with low-fluid safety detection
- VVT control: up to 4 camshafts with open-loop and closed-loop strategies
- Tuning modes: VE-based, Speed Density, Alpha‑N, MAF, and ITB tuning modes
- Self-learning fuel strategy: real-time adaptive fuel tuning
Safety and Protection Features
Making power is easy. Keeping parts alive under heat, boost, and changing conditions is the real win. The EVO+ platform supports safety strategies that tuners can configure to match the build.
- Engine protection: limp mode + check engine lights for critical sensors
- Knock detection: dual DSP-based knock inputs with fine tuning capability
- RPM limit vs temperature: reduces allowable RPM as temperature rises
- Low oil pressure shut down: user-set oil pressure shutdown protection
- Fuel pressure compensation: helps maintain stable engine performance as fuel pressure changes
Advanced Data Logging and Diagnostics
- High-speed SD logging: up to 64 channels at 330Hz
- Real-time clock: timestamped logs for clean review and tracking
- 5 diagnostic LEDs: fast visual troubleshooting and monitoring
Connectivity and Expandability
- CAN support: connect digital dashes, I/O expansions, and transmission controllers
- Firmware upgrades: easy updates with no hidden charges or locked features

Frequently Asked Questions
What’s the difference between MS3Pro EVO+ and EVO+ HC?
They share the same EVO+ platform features (connectors, sensors, logging, strategies, and I/O). The difference is the ignition output type: EVO+ uses logic-level outputs for smart coils / external igniters; EVO+ HC uses high current direct-drive outputs for dumb coils.
How do I know if my coils are “smart” or “dumb”?
Smart coils have built-in igniters/drivers and accept a logic-level trigger. Dumb coils require an external igniter—or an ECU with high-current drivers like the EVO+ HC. When in doubt, check the coil wiring diagram or coil part number documentation.
If I choose EVO+ (logic-level), do I need an ignition module?
If your coils do not have built-in igniters, then yes—you’ll need an external ignition module/igniter. If you’re running true smart coils (built-in igniter), the EVO+ logic-level outputs are the correct choice.
What engines can the EVO+ platform support?
The EVO+ platform is designed to manage up to 12-cylinder engines with sequential fuel injection or 4-rotor Wankel configurations with individual ignition outputs, with broad ignition compatibility across 50+ modes.
Does it support VVT?
Yes. The EVO+ platform supports VVT control for up to 4 camshafts with both open-loop and closed-loop strategies.
Does it include data logging?
Yes. Internal SD logging supports up to 64 channels at 330Hz plus timestamping via real-time clock, along with 5 diagnostic LEDs.
Can I integrate a dash or expand I/O?
Yes. The EVO+ platform supports CAN connectivity for dashes, I/O expansion, and transmission controllers.
Ready to Run the EVO+ Platform?
If you want a standalone ECU with deep capability—fuel, ignition, race strategies, logging, and safety—choose the EVO+ platform and select the ignition output version that matches your coils.
