Richard I ll be glad if you add 2008 s3 2.0 t fsi wiring diagram too.

Re: AUDI specific wiring diagrams...
 

I did a little research, audi S3 turbo has many many engine codes:
1.2 TFSI (2010 on ) ........... CBZB
1.4 TFSI (2007 on) ........ CAXC
1.8 TFSI (2007 - 2008) ....... BYT/BZB
1.8 TFSI (2009 on) ......... CDAA
2.0 TFSI (2004-2008) ......... AXX/BPY/BWA/CAWB
2.0 TFSI (2009 on) ............. CCZA
2.0 TFSI (2006 on) S3 only ................. BHZ/CDLA
2.5 TFSI (2011 on) RS3 only ................ CEPA

Which one is yours?

Re: AUDI specific wiring diagrams...
 

BZC001301 is written on engine bay.
So which one is the proper one I can't figure out.
Do you have any idea?

Re: AUDI specific wiring diagrams...
 

I working on them. Only recently I realised how many variations are there. Luckily the engine mangements stay pretty constant.

It is just as simple easy to splice it at the fuel injector rather at the ECM.

I would welcome anyone who can submit any useful ECM pin out to help.

Hi Richard, I'm going to install the HFS-3 on an audi s2 ABY, and my question is if you know what wire I need to cut to install the fail safe, boost cut, and what wire is the inj#1

I think the signal inj#1 that I need, It's pin 36, is it right?

For the boost I have a external MAP sensor, because don't want to weld one wire on ecu, do I need to cut the boost signal wire and intercalate white and brown wire after blue wire??

I attach you a little scheme of the injection

Thanks!

I was thinking about the fail safe and what I wrote was bad...I think that I need to cut and intercalate the aquamist wires between N75 wire, pin 33, because It's what control the boost, open and close the wastegate

the boost and injector signal I think it's good

Re: AUDI specific wiring diagrams...
 

Yes, you are 100% correct.

White wire to pin33 and brown wire to N75
