Re: Subaru SVX with custom RusEFI

One issue with Subaru documentation is that they don't care about actual VR+ and VR-. This is another area where issue can exist.

Is your crank Hall or VR?

Not sure if that's 1% or 90% of your issue.
Good question. It is VR.
Now it looks 50% better. But enjine is still unstable and I hear cylinder firing skips.

Re: Subaru SVX with custom RusEFI

Adjusting trigger offset in console does not actually moves green line.
Ignition time are quite different per cylinder...

Re: Bluetooth data rate

Yes.
TS has protocol extension that allows TS to maintain list of variables that it needs.
This can increase data refresh rate over slow interfaces.
I'm going to look at this someday.
