About this file
What this original file is
This is the factory calibration of the 1999 VW Golf4 1.8 (110 kW, 150 hp), for its Bosch ECU with hardware 0261206518, part number 06A906018CG and software 352127 (1037352127). 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 VW Golf4 1.8 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 352127 of the VW Golf4 1.8 we sell the original, Stage 1, Stage 2 and Stage 3, each made from the same original read. Every file downloads straight after payment.
The Bosch 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 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 0261206518 is the number on the Bosch ECU's label. Software 352127 (1037352127) is the calibration inside it: a read with hardware 0261206518 and another software number needs a different file. Part number 06A906018CG is the car maker's number for this ECU.
Questions
Which ECU does this VW Golf4 1.8 original file fit?
A Bosch ECU with hardware 0261206518, part number 06A906018CG and software 352127 (1037352127). 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 ECU 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 VW Golf4 1.8?
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 ECU 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 VW Golf4 1.8?
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.
What exactly is in the download?
A BIN file of 256 KB, ready to write. Write it with the same tool and the same connection you read the ECU with.
How do I get the file after paying?
It is in your account as an instant download straight after payment by card, Apple Pay or Google Pay: the BIN file, ready to write.
What if the file does not fit my car?
Send us your read and we correct it free, as many times as it takes. Questions before you buy are answered by a tuner on WhatsApp.
