Motec is exactly as stated. Pay separately for everything. The M series SW is better than the old stuff but still not supportive but, their marketplace is not amateur either, it's what I would term intermediate level.

Got to say, Syvecs\Life SW isn't intuitive either. Again, aimed at above the amateurs.

Maxx have spent tons of time making the system pretty well supported in all aspects of user help and variable options. Probably the most open ecu packed with functions but some of the support team come across and knobs from my experience. Still a very capable ecu.

Non of the above are pro level imo. Non are certainly not OEM level. Some are amateur motorsport spec, non are top flight Motorsport.

The user is the key. My ecu most wouldn't live with, but if your budget is like mine there isn't a more capable ecu.
User interface is key to amateur users.
