Trigger


VVTI actuator

it is PWM two pins


trigger error

sync is working (2013-11-06 logs), vems see rpm but is less secondary trigger error im make log and trigger log

Have reviewed latest logs for proper operation stay with firmware 1.2.11 (downgrade your firmware from 1.2.17 to 1.2.11). Also apply the full configuration not just the trigger section. Several potential other problems have also been corrected.

After this please try again and report - DB

problem with cam sync is solved cam works great

still have problem with rev max 4800 and vems say tooth cnt and next problem with first trigger tooth both problems described below

The logs posted below are taken with 1.2.17 firmware, did you downgrade to 1.2.11 as recommended above ? Your cam sync setup will not work otherwise

yes im downgrade to 1.2.11 and cam sync work ok im load full config but logs im make on firmvare 1.2.17 but is excaty the same problem on this software if you see trigger log vems doesnt see teeth.
