My new FD has sync'd stock turbos. They kick in around 4000RPMs. The boost is controlled by a manual control in the engine bay.

I'm guessing this changes quite a bit in the PFC maps vs the normal sequential twins right?

Should I return it to sequential, is that even possible or worth the trouble at this point?

 

Stock or upgraded twins run either as sequential or non sequential.

What is sync'd turbos. They provide no boost at all until 4000 rpms?
Explain all of this.

 

They're stock turbos. They run non-sequential.
Boost builds probably around 3000, maybe a bit more.

Dunno how it was achieved, since I don't know which owner did it, but I'm assuming this probably.

Mainly I want to know how this will affect the PFC. Mainly I guess its only the boost control part of the PFC that is going to be very different.
I'm trying to figure out if there are "normal" instructions to set up a boost controller with this, preferably with the PFC but anything works really.

Am I making any sense?

 

You need to turn of Seq Turbo Control. Same screen where O2FB is located.

 

I did that. So if I get the PFC Boost Controller It would work fine with that setting off?

 

Yes it would/should. I prefer an external EBC as they have more options than
the PFC offers.

 

What do you recommend? At the moment I have a manual controller, and I don't even think it's functioning properly. I'll have to look it over next weekend when I get to working on it.

 

Boost Controllers, Electronics & EMS - Blitz Dual Solenoid Boost Controller (DSBC) Spec R is what I have.

It allows 4 boost settings, over boost protection, and uses a feedback loop to keep boost very stable between seasonal changes. It uses two solenoids for best boost control.

Most others only use one solenoid.
The earlier Greddy Profect Bs could not do this. Do not knows about the current ones.
