Nope, couldn't tell just by looking - obviously not a mechanical engineer, or bike mechanic.
As for the rest of my post I wasn't trying to criticize your abilities, or knock small teams in general - sorry if it came across that way. Simple fact is no one writes 100% flawless code 100% of the time and as good as small teams can be at developing great stuff, the more complicated a project is, the more chance for errors. And that's where testing and validation by additional people, independent of the developer(s) is a good thing. That's a far cry from designing by committee.
That aside, if what you're developing is inherently safe because it can't interfere with the basic functioning of the ECU, then I'm happy to hear you explain more about that. Of course if you feel that'll disclose too much, I can respect that too.
