About this file
What this Stage 1 file is
This is a Stage 1 tune of the factory calibration of the 2000 MB CLK 320 (160 kW, 218 hp), for its Bosch ECU with hardware 0261206300 and software 350419 (1037350419). Stage 1 is software only: the car keeps its standard turbo, injectors, intercooler and exhaust.
Stage 1 on the 320 refines the ignition timing and the fuelling across the rev range; on an engine without a turbo the gain is modest, the throttle answers sooner.
The MB CLK 320 carries the 320 engine, 218 hp and 310 Nm from the factory. On this engine, Stage 1 usually gives about 230 hp and 330 Nm (+12 hp, +20 Nm). Typical figures for a healthy engine: your car's own result depends on its condition, fuel and parts.
For software 350419 of the MB CLK 320 we sell the original, Stage 1 and Stage 2, each made from the same original read. Every file downloads straight after payment.
Read the Bosch ECU with your usual tool and keep the read: compare its hardware and software numbers with the ones on this page before you write the file.
Catalyst off, speed limiter (Vmax) 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 0261206300 is the number on the Bosch ECU's label. Software 350419 (1037350419) is the calibration inside it: a read with hardware 0261206300 and another software number needs a different file.
Questions
Which ECU does this MB CLK 320 Stage 1 file fit?
A Bosch ECU with hardware 0261206300 and software 350419 (1037350419). 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?
With your usual reading tool, over OBD or on the bench as the tool allows. Write the file back the same way you read the ECU, and keep your original read.
What does Stage 1 give on the MB CLK 320?
Usually about 230 hp and 330 Nm against 218 hp and 310 Nm stock (+12 hp, +20 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, speed limiter (Vmax) off and pops and bangs. 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.
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.
