Staging related setup for MembersPage/NanassyPeter/CloneInstall

TODO: move (and cleanup) any staging notes from MembersPage/NanassyPeter/CloneInstall/Trigger because it will not be answered there

the car has two completely separate fuel lines,with the same componenets,so the injectors are the same in the two groups (higZ,14ohm).


Initial try

First i will try with 2 injectors per cylinder as on MembersPage/NanassyPeter/CloneInstall/Wiring, wired together driven by 5 FETs.

It worked initially, but (surprisingly) with warm engine, it goes rich and doesn't seem easy to tune.


StagedInjection:

First group will run sequentially (on 5 FETs),valve timed, the second group (on 1 IGBT) will switch right after when there is a slight amount of injection time, say after 100kpa or so.

See GenBoard/Manual/DigitalOut/Table for ECxx pins (TODO: update here for complete verification)

That, with (360 degrees rotated) 53124 firing order means firing 10,04,01,02,08 that written reverse is h[0]=08 02 01 04 10 .. .. ..

and with the staging F (20) and G(40) driven together (in last position, that is position 7) it becomes\n

h[0]=08 02 01 04 10 80 00 60

that is

8 2 1 4 16 128 00 96 decimal (as in MegaTune)

The 80 (decimal 128) mask in position 5 is useful so the inj H FET can be configured (eg. for driving ALS kicker valve) with ..channel=50 (in MegaTune, output to injFET-5 or injgroup-5)
