Non-135 tooth related subpage of InputTrigger/AudiTrigger

When installing an auditrigger setup with a certain number of teeth (eg. Porsche ?), elaborate on your project page created from MembersPage and we help configure (working/optimal) divider for the GIVEN (clearly specified!!!) number of cylinders and other related settings (and make bench-tests if necessary).

Other 'Audi' triggers, part 2:

1.1.23 was only ment for 135 tooth. In 1.1.24, since when bit6=1 (primary_trigger=43) is used for auditrigger, auditrigger should work with tooth_wheel other than 5A (decimal 90, that is 135*2 /3 , using divby3).

These numbers come from the number of teeth, and divider (divby2 or divby3). Examples:

For 264+1 trigger: 4cyl 132 tooth and divby3, similar to the 5cyl 135 tooth, just different values (264/3 is 88 tooth and another_trigger_tooth is decimal 22):

If there is no cam-hall masking (HALL is left high), than it becomes 132+1 trigger:

'Please see this MembersPage/PeteKrgr if I got my settings right with 1.1.24 / 132+1 / div_by_2 ??

Also if I change to div_by_3, is then bit7=0 ??

Thanks!

volvo 142 tooth no cam-HALL masking divby2 (bit7=1)

Set the ign_tdcdelay to the angle from crankhome pulse to TDC. Than use strobelight

Porsche 130 tooth normally aspirated (turbo has 132+1 flywheel )

No cam-HALL masking, so 130+1 (not 260+1)

How much tooth was old BMW Motronic?
