We only offer engine control units we have hands-on experience with, each with their own advantages and downsides, but in general, the more options you want out of the unit, the more expensive it is.
We can highly recommend AEM and VEMS engine control units, that offers a wide range of motorsport and racing options, and are tried and tested quality brands with many years of experience.
The advantage to Megasquirt is its a popular brand globally, which makes it easy to find guides and such in nearly any language. They are also a fairly cheap engine control unit option.
Regardless of what engine control unit you decide on, we naturally offer personal guidance on getting it up and running if needed, all you gotta do is write us an email.
