subaru 6-7 help

[Kamuto]

any advice about tracking noise?

[Kamuto]

No loom ,

I have made pcb for direct fit into subarus

it looks really nice :) what software you are using for these?

I Can see that yours is a older model with the old cops,
They a notorius for misfire becourse og cracks under the rubber boot ,

That would be my guess for your problem

yes, it's an older one, but, no problem totaly with stock ecu :) nice power curve without any jumps or something.

I bet its the secondary trigger, this is the sollution on the secodary trigger on the plastic cam gears models
100nF capacitor inline with sensor, 1KOhm pulldown removed, LM1815 pin5 connected to 5V

you are running it with loom adapter or wired it to vems connector?  because I'm running loom adapter for it maybe it is the problem :)

Can you make picture?
Where did you connect pin d6,d4,d5  c1,c2,c3 ?

nope, it's primary one, started it with wasted spark, with 6 tooth trigger,  after 3000 rpm it looses sync, will make picture later

On Many of the older types i have removed the oe ignitor and the problem goes away 😊

you are reading my minds

Here you go wire to wire Color

Thanks, will try this

btw, where should I have to look for it? and how you are controling fuel pump speed for these? or these are simple?

[Kamuto]

so, still chassing ghosts, today  I found one interesting thing.
when engine is cold, no problem with trigger errors, hot engine and it starts throw these when revving.
replaced crank sensor, no change, so what it could be? coils mostly?

d4 primary trigger +
d5 ground near lm1815
d6 sensor ground
c1 sec trigger
c2 ground near lm1815
c3 sensor ground

or d6 and c3 had to be connected to main ground? anyway, it's ok while engine is cold

Bad spark plugs? Something with electrical noise

Also when engine is cold connection to vems is stable. With warm engine you have lot of package lost what indicate lot of electrical noise.
