I ran them without the blend table previously, no problems, didn't have it back then.
I actually had twice as many per runner as well as larger injectors in the second set, so quite a huge difference :)

RE: Injector numbers, I'm not sure there, I see what you mean as the S100 manual says second sets on 6-10, whereas I had it in my head that they followed firing order like the normal wiring - so you'd expect a 4 cylinder setting to start 2nd bank at 5....easy to check though.

The wiring diagram is not clear.

But as long as you have a correctly functioning cam sensor I can see no reason for it not to run sequential

I don't know if it can run sequential or not, I can't see why not, but I was running on a rotary where it wasn't really required.

Hi, sorry to be asking probably a silly question, but I have an S80 Pro, running twin injectors and use the blend map. Is anyone able to fully confirm that if the blend map says 100% secondary injector to be used and the fuel map asked for more fuel than was available, would the ECU then revert to bringing the primary injectors back into play, I have been trying to find a definitive answer to this for a long time, thanks.

Correct.
If either set injectors reach max duty, then the ECU will use the both sets automatically.
