  • Many more features

To have 100% of the features you need the expansion board. Some features may not work in conjunction with others. Some features may require additional circuits external to the ECU. 


The units are sent configured to what the client indicates. No unit is shipped with a finished motor map, they all need an adjustment to the motor in which they are installed, even more when there are modifications. In fact this is what is sought when installing one of our units, adjusting the engine to its modifications or manage systems that with the unit of origin would not be possible. Of course this costs more time, but the results are usually better.


The Megasquirt engine management started as the units with an educational character, they maintain it, over time they have become management units that have the same characteristics as other brands, in some cases higher, much cheaper price and without any restriction Just look at the characteristics offered by each model and the number of fuel and ignition adjustment maps offered.

MegaSquirt® power units are not approved for emission regulations. They are designed for competition vehicles that do not run on public roads, old vehicles that do not comply with emission standards and training centers where teachers can teach students the operation of an engine management unit since inside and without anything hidden.
