About this file
What this Stage 3 file is
This is a Stage 3 tune of the factory calibration of the 2002 Audi A4 1.8T (110 kW, 150 hp), for its Bosch ME7.5 ECU with hardware 0261204897, part number 4B0906018K and software 350204 (1037350204). Stage 3 is written for a car with supporting parts fitted; if yours differ from the usual build, we match the file to them.
Stage 3 on the 1.8T is written for a built engine: a bigger turbo, injectors and fuel supply matched to it, and supporting parts. If your build differs, send us the list and we match the file to it.
The Audi A4 1.8T carries the 1.8T engine, 150 hp and 210 Nm from the factory. On this engine, Stage 1 usually gives about 195 hp and 290 Nm (+45 hp, +80 Nm); Stage 2 usually gives about 210 hp and 325 Nm (+60 hp, +115 Nm). Typical figures for a healthy engine: your car's own result depends on its condition, fuel and parts.
For software 350204 of the Audi A4 1.8T we sell the original, Stage 1, Stage 2 and Stage 3. Stage 2 and Stage 3 each come in two versions, tuned from different reads of this software. Every file downloads straight after payment.
The Bosch ME7.5 ECU in this car is read and written over OBD and on the bench, with tools such as Alientech KESS3, Alientech K-Tag, MagicMotorsport FLEX, CMD Flash, Dimsport NewGenius and Dimsport New Genius. Keep your own read: compare its hardware and software numbers with the ones on this page before you write the file.
Catalyst off, DTC off, speed limiter (Vmax) off, pops and bangs and anti-lag 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 0261204897 is the number on the Bosch ECU's label. Software 350204 (1037350204) is the calibration inside it: a read with hardware 0261204897 and another software number needs a different file. Part number 4B0906018K is the car maker's number for this ECU.
Questions
Which ECU does this Audi A4 1.8T Stage 3 file fit?
A Bosch ME7.5 ECU with hardware 0261204897, part number 4B0906018K and software 350204 (1037350204). Check those numbers in your read before you write it; another software number needs another file, which our engineers can build from your read.
How is the Bosch ME7.5 read and written?
Over OBD and on the bench, with tools such as Alientech KESS3, Alientech K-Tag, MagicMotorsport FLEX, CMD Flash and Dimsport NewGenius. Write the file back the same way you read the ECU, and keep your original read.
What does Stage 1 give on the Audi A4 1.8T?
Usually about 195 hp and 290 Nm against 150 hp and 210 Nm stock (+45 hp, +80 Nm). Typical for a healthy engine, never a promise for one car.
Can you add catalyst off to the Bosch ME7.5 file?
Yes, on request, for off-road and competition use: catalyst off, DTC off, speed limiter (Vmax) off, pops and bangs and anti-lag. Upload a read through our file service and an engineer builds it (any file £50, from £30 in packs). The buyer is responsible for using it where the law allows.
Stage 1 or Stage 2 on the Audi A4 1.8T?
Stage 1, about 195 hp and 290 Nm, is for a standard car. Stage 2, about 210 hp and 325 Nm, is written for a car with supporting parts: a freer exhaust, a bigger intercooler and a clutch that holds the torque, as this engine needs.
