Re: Subaru quad avcs

Recommended Posts

Hi there, 

i have transplanted a Subaru ej207 quad avcs ,into my gc8

is cable throttle so ,no DBW , I having some problems wiring the exhaust cam signal

i used your quad avcs diagram , the only problem is that ,my exhaust cam sensor is 

3 wire Hall effect ,not reluctors , so wired it like the intake can sensor 

but it is not sensing well , do I need to change it to the older model reluctor sensor to

make it work, or just configure the Vvt 

regards

ECU will be fine with the hall sensor inputs, But you will need to have the pullups turned on.

Also be sure to check the offsets for each cam using the cam test function.

Hi Scott 

i am am still having trouble with my exhaust avcs 

funny thing is that is only sensing when I put active edge to rising 

but is running weird on f12 screen Vvt , my exhaust target is zero bit posn is running 

and idea what could be wrong , 

I am still running the Hall effect sensor for the exhaust rather then reluctors 

regards

Have you check the cam offset figure buy using the cam test function.

If the offset is incorrect you will see this sort of error.

The help file explains how to do the cam test.

Oh ok will check , funny thing is the solenoid duty can be seen at 30 percent 

even cam targets are 0 degree 

could there be a wiring problem ,for the Hall effect triggers that I could have 

wired the positive to negative and vice versa that's why is running on 

rising edge ?
