    MTM ECU/TCU for my RS6

    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.

    Paul

    Not sure what you mean by "purchasing used chips". Technically you can get those 44-pin PSOP flash chips in case someone decides to desolder em, but I highly doubt that anyone would do that. But you probably can get "a copy", I guess.

    TCU has to be soldered, ECU can be done via OBD.

    Not the best tune.

    Go to 034 motorsport and buy the complete package.

    Good bang for buck and support

    Also check eurocharged tune for ECU, they send you a hand held device to tune, there is no down time for you. I had eurocharged tune, very consistent, no drama. Oh and the support is awesome, I had revision files sent to me same day as requested. As far as TCU I have no input.

    I am going to look at an rs that has mtm badging - I assume its been tuned - how can I tell? - I seem to recall there is sequence of manipulations of the blinker stalk to activate the tune? -- or is that APR? -- The rs I own is not tuned. Thanks for your help

    The only way to verify for sure is look for the MTM seal on the ECU/TCU itself.

    If you're in Seattle, contact AMD. Best Ecu/tcu tunes for the rs6 by far.

    Only way to confirm ECU is log data, check boost, Ross-Tech.com. Paperwork I guess...

    TCU is under carpet of passenger footwell, see if it's been opened and new chip soldered in.

    Any of the top tunes will be good, AMD, Daz, 10secS4, 034, MTM....but I'm sure one is a bit better.

    Being local it makes more sense. Dyno before/after etc

    Agreed. Crap, I was even able to get decent results with enough dyno/street time using my amalgamation of Revo and Unitronic...but it took a lot of fine tuning.

    Congrats and well come to the forum! A wealth of knowledge and information here. I have the APR tune ECU/TCU but not sure if they support this platform any more.

    Anyone have APR tune and comparisons to other tunes mentioned here? My car came with APR ECU/TCU tune when I bought it. Since APR does not support this platform anymore so I wanted to see what other options are available. How does one go about getting the Daz tune?

    I haven't logged the car but it currently spikes to 17-18 psi with 14 psi steady. Only issue is that it seems "laggy" in regular Drive mode, however it seems less laggy when I use it in manual mode. I am assuming this is DBW throttle lag, it took me took a while to adjust to it.

    Do you guys notice this lag in normal Drive mode?

    It seems the early APR tune was a bit more agressive. If you data log I can tell which one you have.

    I dont know if daz or 034 can flash the APR emcs piggy back. They may need to replace the chip

    Thanks Dave...will send you logs as soon as I get them. No issues with the tune, just curious what other options are there.

    Not sure if it's my ACE rebuilt TC or the way my tune is set, but my car feels very snappy off the line. So much that I usually ease into the throttle to not snap my head back, and now with winter tires they spin easily when cold and and debris on the road. This is with all gear settings, but it seems more aggressive in Sport, and much more grab on down shifts.

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