Hello,
i want to install my Borgwarner EFR 7670 IWG Kit from Turbosorce.
But i have no clue how to wiring it.
My ECU is a Apexi Power FC, i changed my old Dataloggit to a DL-340XB from FC-Tweak.
I saw that Raceonly have a "EFR Boost Control Harness Plug and Play", but i donīt know if i really need that.
Fuelsystem is still complet stock, i donīt know what i need.
I heard good about Radium products, but i donīt know what i must buy, and which injectors.

My goal is to have a well-drivable car with a maximum of 340HP.

I hope u can help me out.

 

Look at both of these threads.

Hello,
thank you very much for the information. I've read both of them several times, but I still don't fully understand.
The turbocharger comes with a solenoid valve. So, if I understand correctly, I connect the two cables to the original wiring harness of the wastegate solenoid valve?
What happens to the precontrol and turbocontrol solenoid valves?

 

Find the pre-control solenoid connector in the engine bay and make a patch harness to connect it to the Pierberg solenoid on the EFR. The black/white(stripe) wire is switched 12V power and the blue/yellow(stripe) wire is the switched pre-control ground signal from the PFC, wire orientation to the new solenoid does not matter- it's just a coil.
It's on page z-32 of the USDM '93 wiring diagram.

Once that's done turn the sequential control off just like Chris says here: https://www.rx7club.com/single-turbo.../#post11405955

 

This helps me a lot! Thank you so much.

 

I have the same setup as you and I use a standalone boost controller to control boost pressure. Yes you can use the Power FC to control boost however as I understand it its best to use a standalone boost controller.

 

agree with this.the power fc is not good at controlling boost on single turbo
