About this file
What this Stage 1 file is
This is a Stage 1 tune of the factory calibration of the 2008 VW Touran 1.4 TSI (103 kW, 140 hp), for its Bosch MED17.5.1 ECU with hardware 0261201541, part number 03C906032C and software 396313 (1037396313). Stage 1 is software only: the car keeps its standard turbo, injectors, intercooler and exhaust.
Stage 1 on the 1.4 TSi (CAVC) raises the boost, sets the ignition and the fuelling to match and lifts the torque limits, within what the standard turbo and fuel pump hold. It wants the fuel octane the car was made for, or better.
The VW Touran 1.4 TSI carries the 1.4 TSi (CAVC) engine, 140 hp and 220 Nm from the factory. On this engine, Stage 1 usually gives about 200 hp and 300 Nm (+60 hp, +80 Nm). Typical figures for a healthy engine: your car's own result depends on its condition, fuel and parts.
For software 396313 of the VW Touran 1.4 TSI we sell the original and Stage 1. Stage 1 comes in two versions, tuned from different reads of this software. Every file downloads straight after payment.
The Bosch MED17.5.1 ECU in this car is read and written over OBD and on the bench, with tools such as Autotuner, MagicMotorsport FLEX, CMD Flash, Dimsport New Genius and Alientech Kess V2. Keep your own read: compare its hardware and software numbers with the ones on this page before you write the file.
The same 1.4 TSi (CAVC) engine with the same ECU is fitted to the Volkswagen Golf V: 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 and pops and bangs can be added to 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 0261201541 is the number on the Bosch ECU's label. Software 396313 (1037396313) is the calibration inside it: a read with hardware 0261201541 and another software number needs a different file. Part number 03C906032C is the car maker's number for this ECU.
