About this file
What this Stage 1 file is
This is a Stage 1 tune of the factory calibration of the 2008 VW Golf5 1.4 TSI (103 kW, 140 hp), for its Bosch MED17.5.1 ECU with hardware 0261201768, part number 03C906032C and software 393651 (1037393651). Stage 1 is software only: the car keeps its standard turbo, injectors, intercooler and exhaust.
Stage 1 on the 1.4 TSI 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 Golf5 1.4 TSI carries the 1.4 TSI 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 393651 of the VW Golf5 1.4 TSI we sell the original and Stage 1, each made from the same original read. 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, Dimsport New Trasdata 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 engine with the same ECU is fitted to the Volkswagen Touran 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 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 0261201768 is the number on the Bosch ECU's label. Software 393651 (1037393651) is the calibration inside it: a read with hardware 0261201768 and another software number needs a different file. Part number 03C906032C is the car maker's number for this ECU.
