About this file
What this Stage 1 file is
This is a Stage 1 tune of the factory calibration of the 2001 MB C 230K (103 kW, 140 hp), for its Siemens ECU with hardware 5WK90420 and software ID 1M10006201005. Stage 1 is software only: the car keeps its standard turbo, injectors, intercooler and exhaust.
Stage 1 on this engine 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 file is listed for the 103 kW, 140 hp version of the MB C 230K. Check the power on your car's papers: the same model was sold with several engines, each with its own file.
For this calibration of the MB C 230K we sell the original and Stage 1, each made from the same original read. Every file downloads straight after payment.
Read the Siemens 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, DTC off and speed limiter (Vmax) off 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 5WK90420 is the number on the Siemens ECU's label. Software ID 1M10006201005 names that calibration in your tool's read.
