Bad idea using M box tune on an RS4 imo.  There are a LOT of differences.  Not just the maps, but certain functional aspects.

yes it will

Yes this should work

Thread resurrection.  OK guys let me explain the problem I'm having here.

I have an A6 2.7t 6mt ecu which infinkc boot-mode forced an m-box file.
When I flash any m-box tune, i get no warning about IMMO.  This would make sense because my car is an a-box car and nyet currently believes that m-box has no actual IMMO routine in it.

However when I flash the RS4 K-box tune, IMMO definitely shuts my car off.  I'm writing all of this, because I know that infinkc did a boot-mode write of the m-box tune the first time, and I've been flashing the car since then with no problem.

So, what I think I now understand by having written all of this.
infinkc likely did not use the 95040 EEPROM reprogram.
he simply forced the car into boot-mode, which allowed the bin to be forced on to the ecu.
after the intial bin was written, the ecu runs normally, because the m-box doesn't care if immo is on the eeprom or not.
finally, when i went to the k-box tune - the EEPROM which wasn't reprogrammed yet blocked the ecu from doing anything.

does this all sound logically correct?  it took me a bit to piece this all together because i assumed the m-box's tune being on the a6 ecu implied the IMMO had been defeated at some point.  does anyone see my intial conundrum here?

for anyone that has used an a6 6mt, did you have to modify the EEPROM?  i believe the answer is now, but you did need to use boot-mode to get your first flash finished.
