HFS-6 setup in a 2000 Audi A6
 

Here's a shot of my engine (haven't put the covers back on) with my custom accordian hose replacement to fit the 90mm MAF housing:

Here's a shot of where I have the jets located, until I can get a spare intake manifold and do my 6-jet direct-port setup:

Next the tank and pump location. You'll have to pardon the power wires all over, I'm using a distribution block that will also power my amps, and until I figure out exactly how I'm mounting them, I haven't bothered to mount the block yet:

As usual, flawless installation, despite the AZ heat. Please post more pictures and any details you can, make this thread an informative one.
Do you have a picture of the FCM?

I knew I forgot something important! :lol:
I'll get one tonight and post it up. Right now I'm enjoying the "stealth" aspect of the installation. It'll be better when I got direct-port, as you can't really see the intake manifold at all.

Do you have n ECU pinout diagram for me to produce a A6 specific wiring diagram for future A6/H6 users?

Sort of. I have a number of pdf files showing the wiring, but it's not all together on one sheet.
If you get me your email address, I'll send you what I have.

My email address is richard@aqamist.co.uk Anything you have will be gratefully received.
