There has always been and probably always will be an injector output table. It's in the Base setup menu.
The visual dialog is the best for this purpose.
I think like this when it comes to firing order:
As the software can setup the firing order of the injectors, that make the most logical way to understand which injector fires when to connect cyl 1 = A, cyl 2 = B, and so on.
Then setup the table (which is traversed in reverse order) to fire injector 1 on the bottom row (row 8 = injgroup
, then injector 5 for row 7 = injgroup 7, and so on..
