subaru trigger settings

Skassa - I agree with what you're saying with re-use of OE stuff.

There is a 36-1 disc for the Subaru EJ20 used by Pectel if all else fails.  (I hope it doesn't, but I like options)  6 tooth crank discs are always going to be difficult.

Yes , i did see that Pat showed it on 22b years ago, but i just think that whe other Ecu manufacters can make it work,so can we .....I hope .

Sorry rob, i just assumed that it was the same noise problem.


I still havend had the time to work on it, as my son had his 4years birthday today, and tomorrow i have to get the Forged HKS Subaru engine together, as the owner would like torun some 10sec passes

Happy birthday for your son.  It should have been my daughter's zeroth birthday yesterday - looks like she's a typical woman, and not ready yet...

There will be an obvious solution for the trigger somewhere.

This is going to be a big day for You All, when it happens

I hope so, but do you know were i can buy the 36-1 wheel for the Impreza?, and at what cost?
As i have to make a Impreza within 2-3weeks


Thanks,

I believe Pat still sells them.  The trick is pinning him down to give you a price and take money off you...

No idea on price unfortunately.

There seems to be a small strage thing with the subaru trigger, as when i needs to set the tdc delay, it only moves half of what i write, meaning if the tdc delay is 80degrees, and i measure the crank advance to 30degrees, and the setting is 15 , if i then the delay to 65 ,
then it will measure 22,5degrees why is that?

I have quite simply no idea on that one, if the effect is constant then you should be alright - its good practice to strobe the engine right through the rev range.

[Denmark]

I also strobe it across the rpm range, it´s just when setting the tdc delay, that it´s off,
So it must be a simple error i the subaru config.

Hmm,

I was out mapping the car last night, and the advance is indeed of, as it i strobed it at 10degrees, so this is right, if i write 40 degrees in the field the this will be 10degrees that´s fixed + half of the rest, that is 40degrees- 10degrees = 30 degrees, then half of that =15degrees+the 10 fixed , so this will be 25degrees advance in total,

This is extremly strange, as it´s the config i downloaded from one subaru to another, and it´s right on the first!.

It´s a bit of trooble to map, and i can only get 37.5degrees , as the max that can be written is 63degrees.

Can you not adjust the "TDC after the trigger" parameter?

[Denmark]

Yes, i can do that, but it´s just a pain, that the advance is not right, when i know around what numbers that needs to be filled in,
But i also found out that there is still some noise on the trigger signals on this one, when cranking, but it´s not all the time, some of the times i can start the car, without the "trigger error" is light,and it also starts easyer when this happens..

Any suggestions to make the Vems able to read the trigger signal, if perhaps you know a chip the can be inserted, that will clean it up, or some other suggestions?

If I were you I'd be plastering this information on the Wiki, because the developers will never see this.
Shame that it is they all use the Wiki.
