36-1 crank with 2 camsync
« on: November 20, 2010, 05:24:08 pm »
We have a cosworth yb engine which originally equipped with 4-tooth crank and 2-tooth cam trigger as on http://www.vems.hu/wiki/index.php?page=InputTrigger/LanciaCosworth
But we use 36-1 crankwheel with no camsync.
Now i would like to use the original camsync with 36-1 but i don't know whether vems can ignore one tooth from the two.
i have made a triggerlog:

www.cosworth.hu/misc/v3.3_n001433-2010-11-20-11.52.21.triggerlog

this is the test config (log says no rpm, and there are trigger errors):
http://cosworth.hu/misc/sec_trig_test_v3.3_n001433-2010.11.20-10.07.02.vemslog

fw version is 1.1.84 now...

thx

i don't want :D

Software sollutions are more elegant :)
There are a sec trig min and max angles with option filtering "event at bad trigger position" but no work.
There is a multitooth option at type too, but if i set then mode will be invalid.

I think it's much easier to modify hardware to make it work :) You know that since you have cossi with 36-1 ;)
If you have everything under control, you\\\'re not fast enough!
