Life Racing do make the ecu's for Syvecs, but they are a cheaper brand and are also developing in their own right.

Much the same as Link/Vipec. Same manufacturer, same origins of both hardware and software, but developing along two different paths, Vipec more quickly it seems.

Knock sensor inputs.

Injectors...something makes me want to say 16 injector drivers...ie 2 per cyl V8 application. It is of course serious overkill though, especially with the current range of high flow injectors available today.
12 coil drivers ? perhaps too many

Maybe both of the above are inexpensive anyway ?

COMMS...I think USB has to be in there, simply for tablets and other such devices. Bluetooth ? Maybe WiFi is a better option ?

Another possible feature...and might assist setting up multiple cars.

Crank and cam signals are always repetitive..obviously. Yet setting these up for cars where they havent been done by the ecu maker...always seems to be a ballache.

I really dont understand why the ecu cant simply learn the trigger ?
Suggestion.

Remove all plugs bar cylinder 1. Crank engine over a few times. The ecu sees and learns the crank/cam signals, it can detect cyl1 as it will be the only one on compression, so rpm will change.
Job done.

Obviously once running, timing will still need verified with a timing light. The user would still need to define sensor type, ie VR or Hall.

The Adaptronic e1280s is another very well spec'd unit and competitively priced.

It's software claims to allow you to to almost anything with it's outputs, and offer a huge level of control and features.
I'd actually like to try this one myself....but I did try the software and just cant get my head around it
