MTM ECU/TCU for my RS6

[ben916]

Good morning from Seattle:

I am a new owner of a 2003 RS6 and am looking to upgrade the ECU/TCU soon. I called the MTM representative and he said that I would need to send in both units, they would ship to Germany for the upgrade and that it would take about 2 weeks. There is nothing that I know of stateside for the beast.

My question is this: can I purchase used MTM tuned chips and drop them in the vehicle? It may not even be a possibility at this point and I have not looked for a tuned ECU/TCU. I would assume that they have to chip your existing ECU, but I have no idea.

Thanks, love the forum, love driving the beast even more and I look forward to you reply's.

Details: 125k, "fresh" 48k engine at 120k due to 3:00am garage shenanagins. Totally stock but scheduled for a ECU/TCU tune by AMD this Friday.

Does AMD do remote tuning or do you have to swap ECUs?

[lagerstedt]

I do not know for sure. I found out that they were 10 minutes away from where I work so I just stopped by and met with Jason and Mike. Their contact information can be found at www.fastaudi.com. or 425-424-2165.

No, mine VIN was 905355 and it was driven like a grandpa to the store to get milk after breaking the non-"bufkin" piece. The last time I got squirrely with it was with Wade around San Marcos = next day I had a large pink puddle under the passengers side front and thank goodness for the aftermarket warranty as the bill was $5300 to fix it...

Paul has the debbil VIN!!!

Not just the debbil VIN but the mark of the Beast! (Rev. 13:18) I would say that is pretty fitting considering...

Getting excited for the tune at AMD in a couple of days. I forgot 1 thing on the modifications - I deleted the rear mufflers and replaced them with straight pipe and the stock tips. It sounds absolutely perfect and garners just enough attention when you get on it to make the occasional head turn and stare. Cost was about $200.00 at a local custom exhaust shop. I'll post some video of it soon if anyone is interested.

Try and get your dyno sheet with before/after numbers, would be interesting to see. Have fun!

[lagerstedt]

Definitely. Should be interesting to see. I'll take some video, too.

If feels laggy (throttle lag) in regular "D" mode off the line..partial throttle though

Hmmm, might be the computer doesn't signal the TC to engage as quick, results in smoother driving around town. I'd say up and down shifts are smoother in Drive, Sport and Tip can be grabby unless the RPM's are just right.

Cool, interested to see their numbers on a mostly stock car.

Dave, how hard would it be to add e85 to the RS6? and would I need a reflash of the ECU?

New tune, new injectors, new fuel pump(s), and possibly new fuel lines...

You're kidding right? Completely change the fuel and question a reflash...

I think? one of the members on this forum has done this, but don't quote me on that. It requires hardware and software changes both and unless you're an avid wrencher, I don't believe it's worth the hassle.

[AUDI5000CSTQ]

Thank you all for the input. Sounds like way more of a hassle than it's worth. Just need more power.

You could add water meth and update the tune, maybe get you 20-40 more hp/tq. Maybe just try a more aggressive tune. Problem with more power is it starts getting easier to break the trans. I've settled where I'm at and make the most of it, still decent numbers.

[AUDI5000CSTQ]

The Water Meth might also help with heat soak. i start off at 9.1 sec in the 1/8th mile and lose .1 sec each subsequent run there after.
Really need to just break into the 8 seconds. Maybe a Eurotune 2, but would like to switch to 100 VP racing on demand. don't know if Euro tune or 034 allows that.
