MaxxECU Comparison Tool – Find the Best Standalone ECU for Your Setup

How many cylinders does your engine have?

Enter the total number of injectors, please bare in mind, the MaxxECU Mini & Street only support high impedance injectors by default.
All other ECUs are capable of both.

Sequential: 1 coil and 1 injector per cylinder.
Wasted Spark: 1 coil per 2 cylinders, 2 injectors per 1 output.

All MaxxECUs are capable of driving 3 high impedance injectors from 1 output, however, it's advisable to pair.
Please Note: It is heavily advised to pick an ECU where you can wire one injector per output to futureproof your build.

All ECUs come with an inbuilt MAP sensor & dedicated input for 1x Throttle Position, please do not count these in your total as they've already been accounted for.
Consider Fuel Pressure, Oil Pressure, Shift-Force Sensor as alternatives

All ECUs come with dedicated inputs for Coolant & Intake temperature as standard, please do not count these.
Consider Oil Temp, Pre-Intercooler IAT, etc.

These are typically switches to GND or Hall Effect Speed Sensors (e.g. clutch switch, launch/brake switches, etc).

Some ECUs (Race, H2O, Pro) allow VR sensor inputs to act as digital inputs.
Used for high-speed signals like wheel/driveshaft speed.
Leave as 0 if unsure.

Number of DBW throttle bodies.
Only supported on MaxxECU Sport & above.

Used to detect detonation & protect the engine.
Only Race & above support internal knock sensing.

Number of Exhaust Gas Temperature probes (e.g. 1 per runner, pre/post turbo).

Required for full sequential spark/fuel on most engines.

Used for fan relays, boost solenoids, fuel pumps, VVT, etc.

High-side outputs. Only supported on Race & above.

Allows use of the MDash app, which provides real-time values and datalogging straight to your Android phone or tablet.

Wideband O2 controller channels built into the ECU.

Choose "Yes" if the ECU will be exposed to weather or water.
