Only after seeing your post on FB...
I see the areas now you refer to. Does look odd...although also why is FP dropping too ?
Could be an electrical gremlin of some sort. Fuel final does drop too in response to thinking it is rich.

Re: WB possible failure
Everywhere in that log it looks to be working ?
Exactly where do you believe it is not on that log ?
Although fuel pressure does seem a bit odd. What engine is this ? A normal port injection or is there direct injection too ?
If normal port injection, your base fuel pressure of around 5 bar a ...

Re: S7Plus vs S8
What is the application ?
Software is same for each.
CAN is more flexible on the S8 so if you need CAN devices or may want to add an expander, that could be a consideration.
S7 setup/comms/CAN seems to offer easier integration with factory cars that have multiple modules that need talking to and ...

Re: Primary / Sec injector opening time scale modification
silly me.
the breakpoint adjustments for that table are literally above it, Injector opening time axis.
3000mbar on the table would be 43.5 psi, yes.
As a baseline, engine off, FP and relFP would be the same at normal "1 bar" atmospheric conditions, so filling in the table with their values ...

Re: Primary / Sec injector opening time scale modification
you would need to pick your baseline pressure in terms of flow, then everything else is relative to that.
eg, if you choose base 60psi, that's your 1.00 in the relFP table
edit, I was arse about face...
43psi 2044/1728 = 1.183 is your multiplier for the lowest pressure offered
100psi 2044/2645 ...

Re: Dwell times Subaru black coil packs.
It really does not need a complicated table.
It can be as simple as say 0-2000kpa 3.0ms, 2000-3000 3.5ms and 3000kpa+ 4.0ms, just as an example. That's only 3 rows.
For rpm it can be as simple as 0-4000rmp, 4000-7000rpm and 7000rpm+, again, that's only 3, you have 4 rows available. There really ...

Re: Dwell times Subaru black coil packs.
Subaru have made a lot of coils over the last 30-40 years, you'd need to be a bit more specific.
But yes the table can be changed to RPM, but boost/MAP would be more typical.
Change in View/Customising options.
Best way to determine optimum dwell for your specific coil is get a scope and current ...

Re: More water / meth injection
I would think 10L would be a struggle for such a long session. Of course, depends how often that is under load where you would be spraying
Even if A2A is difficult, maybe a A2W setup might be easier ?
Intercooling is fit and forget, no concerns about running out.
Of course, you can of course have ...

Re: More water / meth injection
I would always try and fit the best cooler you can, whether that's A2A or A2W, whatever permits.
With a good fuel like ethanol, not sure if water will be a massive benefit though ?
Certainly Peter aka RiceRacing would be the man to speak to for a more complex setup.
