InputTrigger/HondaFTwentyTrigger (2008-03-07 08:57:24)

Honda F20

From the S2000, this is now a popular engine conversion into older cars and Lotus 7 replicas as it is an RWD engine.

There are 12 equally spaced teeth 30 degrees apart, with an additional tooth positioned ~20degrees after one (~10degrees before the next).

The engine turns clockwise (apparently this is the only Honda VTEC engine that does) so the trigger pattern is:

..., 30, 30, 10, 20, 30, 30, ...

Suggesting that this trigger cannot be used with InputTrigger/ShortGapTrigger (See below)

It does look as if the trigger could be turned over and refitted which would give the pattern:

..., 30, 30, 20, 10, 30, 30, ...

Which might make the missing tooth setup work correctly.


did you try with missing tooth setup

If gaps are 30,10,20,30 than a variation of InputTrigger/ShortGapTrigger that is not yet supported, I think (because it would also require shortgap at the next event to be fired, 180 degrees later in a 4cyl)
