open question of x8 injectors should be the default HW config
Can not. There are only two drivers in the pump bank: High Side and Low Side. The bank of injectors contains four: two High Side and two Low Side.
@NOx-z ?
IMO the 6ch is a mistake in the first place.
But. That again seems like unnecessary complexity - why do we want to make our lives more difficult doing that? Why not run two 4ch boards on a v8?
Pt2000 board is PnP into 760 test mule harness

sure - seems like we should do 100/200/500 miles on VW 4cyl before spinning another very similar board that will have the same problems we detect (if any) on the 4ch.
Any High-Side driver can be used as Low-Side. This is true for the PT2001/MC33816 as well.
The PT2000 mentions this in the datasheet at (page 41 in pdf):
6.3.3 High-side pre-drivers in low-side configuration
and all drivers are accessible by any channel/core, but there are some special situations where only the dc-dc boost is applicable.
a configuration of 2 banks would include using 2 high side drivers per, as high side drivers (typical vboost and vbat) , and then a total of 4 more drivers (mix of high side + low side) as low sides. For a total of 8 cylinders.
the PT2001 can use the 'fuel pump' drivers in order to drive 6 total cylinders, and no 'pump'/fuel limiting valve

@mck1117 i can agree to one mile. I am a believer in separation of responsibilities, once it did a mile i would need others to step in
seeing as nobody else owns a GDI vehicle they're willing to ecu swap - that separation of responsibilities (as you call it) would require you buying me a car
I like that plan!

@ElDominio I know you've made a dyno video about GDI Hyundai but do you know if any of those have put any miles?
technically PT2000 can drive x8 of injectors instead of driving fuel pump
let's have flexibility via HW jumpers if jumpers are needed
