What's in a number?
I’m assuming by changing no. 1, it means either the left or right bank is now leading, which was probably necessitated by the firing order change and how the turbo is packaged....
iirc and imo etc ....
there was much discussion about 6 years ago re different V6 firing orders ..... and ....
gg said all the apparently different firing orders were actually identical ...
.. I said that a possible difference was if the orders within the 2 banks were 'different' (to each other) ...ie .............
if left bank sequence was beginning-middle-end cylinders and right bank sequence was beginning-end-middle ......
with the usual airbox that order could have an effect on the inconsistency of cylinder filling and combustion ....
(as has been shown eg on the F1 NA V10 Ferrari to be caused by inconsistent behaviours in the induction tracts )
this could be particularly important at the unprecedentedly high borderline-unreliable AFRs used in F1 ICEs since 2014
