About this file
What this original file is
This is the factory calibration of the 2007 Audi TT 2.0 TFSI (147 kW, 200 hp), for its Bosch MED91 ECU with hardware 0261S02084, part number 8J0907115 and software 386455 (1037386455). Use it to put the car back to standard, to recover the ECU after a failed write, or as the base of a tune of your own.
An original holds every map as the factory wrote them: ignition, fuelling, boost and the torque limits, the speed limiter and the emissions controls. Tuners start a file from it; workshops use it to put a car back to standard.
The Audi TT 2.0 TFSI carries the 2.0 TFSI engine, 200 hp and 280 Nm from the factory.
This file of software 386455 of the Audi TT 2.0 TFSI downloads straight after payment. Another stage of it can be built from your own read by our engineers.
The Bosch MED91 ECU in this car is read and written over OBD and on the bench, with tools such as Alientech K-Tag, Autotuner, MagicMotorsport FLEX, CMD Flash, Dimsport New Genius and Dimsport New Trasdata. Keep your own read: compare its hardware and software numbers with the ones on this page before you write the file.
The same 2.0 TFSI engine with the same ECU is fitted to the Audi A4 B7, Seat Altea, Seat Leon 1P, Volkswagen Eos, Volkswagen Golf VI, Volkswagen Jetta V, Volkswagen Passat B6 and Volkswagen Tiguan I: their file can be the same, so check the software number of your read.
Catalyst off, DTC off, speed limiter (Vmax) off, start/stop off, pops and bangs and anti-lag can be built on this file on request, for off-road and competition use: send us your read through our file service and our engineers add them (any file £50, from £30 in packs).
Hardware 0261S02084 is the number on the Bosch ECU's label. Software 386455 (1037386455) is the calibration inside it: a read with hardware 0261S02084 and another software number needs a different file. Part number 8J0907115 is the car maker's number for this ECU.
