Subaru STI 2004 avcs cam settings

Post by roquete » Sun Mar 03, 2019 10:15 pm

Hi there, hope you guys can help me out with this 2004 Subaru Sti JDM specs with avcs and 3 cam sensors and emu black.
- I have wired the sensors as per manual with cam advance sensor for left cam on VSS and right cam to cam#2.
- engine starts and runs, needs much more tuning but i came across this problem so firstly trying to solve it.
- problem is i put cam offset to something like 178 to get the 0 degrees in the log, it stays that way but after i turn off ignition and start again i see something like -58 degrees in log and i have to go again to cam offset and up the value to something like 260, then again shut off the engine and on its again out of the 0 degree, again i have to put 178 in cam offset.
- i send the log, project and scope, i think it has something to do with min and max tooth in cam#2 setting but i cannot count the number of tooth as the primary trigger scope it does not apear the first tooth or any blank space (why is that too?).

Solved, hbrige outputs should not be used for cam solenoids, it outputs positive 12v when going high.
