Is there anyone actually running a chipped T-Box ECU where their original ECU was a M-Box? I'm looking to get a chip (choices were MTM or ABT) and there's someone selling their T-Box ABT-chipped ECU, but mine is a M-Box. I want to make sure before I lay down a wad of cash on this.

Thanks,

It will work just fine.

T-Box works just fine in 2001.5 S4's that originally came with M box. No difference.

Do you even have your S4 yet? "Soon: 2001.5 Nogaro Blue S4"

Need to make plans beforehand - already purchased a SS, looking for a chip and suspension and about to book a date for exhaust install.

Does that sound crazy? Buying my mods before I pick up the car (rereading that it does!!!)...

P.S. Anyone selling an ECU\Chip (pref. MTM or ABT M\T Box)?

last thing you want to do is throw a bunch of mods on day one and then find out the thing doesn't run right.

guess that's a tad different though ;-)

I used to run a stock T box in my M-box car. It works fine. They are interchangeable.

It seems that the M-box has been superceded to the T in the Audi parts system.
