Ok I gotta make it short I'm @ work..

I'm going to turbo my s4 na.. It this rtek the way to go I need something for fuel air and timing management.. I thought about a safc neo but decided against it. Any feedback will be helpful!

 

It works best if you purchase a turbo ECU, MAP, and AFM, and install the Rtek in the turbo ECU.

 

^ what he said, then you're good to go.

 

thats what i did i got all the electronic for tii and threw it in my, i also port matched the tii intake to the 6port block.

 

Ok, I have a second question to bounce of this main topic, will the Turbo II ECU work with the NA harness?

 

Yes your NA harness will work on the USDM Turbo II ECU but not the JDM ECU. It will start with the JDM ECU but will not run right.

 

I'm not really sure where to look, but what numbers should I look into for the ECU I found an N332 that I am told is a S4 TII ecu that I can run on my Series 4.

What other numbers do I need to look for, for the other parts, AFM, MAP, etc.

 

yes it will with only minor modifications. rtek would need TII ecu numbers N332 or N333. boost sensor N318 i think is what it says on the top... maybe N327... i'll go look under the hood tonight and tell you for sure. i think i have that mixed up. ecu numbers are correct. AFM... i'll just go look because i dont wanna tell you a wrong number. but basically just find any S4 turbo afm and you'll be good to go.

 

Let me know what you find.

 

I was wondering what kind of modifications you were referring to.

 

The S4 turbo boost sensor PN is N318, and it's the same for the AFM. The only modification needed to use an N332 or N333 ECU with an NA harness is to cut the wire at pin 1R. This is the knock sensor pin for a turbo, but the wire runs to the P/S on an NA. It's related to the idle up function, so the P/S still works fine.
