I'm a total noob and just found this site and the amazing resources surrounding it.  I've got a 2000 D2 A8 and then there's this STS-V supercharger sitting on the shelf.....hmmmm   ...so I was wondering when going from NA to boosted what would be the best strategy.  Originally I was planning an AEM FIC piggyback to handle fuel and timing on boost.   But I would love to reflash the stock ECU instead.  I'm thinking at a minimum I'll need a MAP sensor to replace (or supplement) the MAF sensor and a bit of harness hacking.  My question is at the outset, should I be looking for an ECU from a different boosted V8, or could I tell this one to expect to see positive manifold pressure.  Figure I'll never go higher than 12 or maybe 15 psi. I may have to knock down my compression a a point or two as well. What would be the better starting point: utilizing my NA ECU or using one from a boosted Audi V8 application?

To that end, I'm also wondering if I can wipe a spare A8 box, flash an entire RS6 map and then adapt it from there.  The last time I played with this stuff was way back ...oh er...uhmm...15 years ago tuning a GM box for a 3.4 swap into an MGB.  Time to dust off Excel ninja skills.

Also switching the tranny to a 6 speed manual.  The entire project is a few months away...still picking up parts and also rehabbing my new-to-me house...kitchen almost done...only 3 bathrooms to go.


Thanks in advance,

But the best starting point would be a fully defined RS6 base file. Without that, you'll go nowhere.
