About this file
What this Stage 1 file is
This is a Stage 1 tune of the factory calibration of the MB SLK 230K 2.0 (142 kW, 193 hp), for its Bosch ECU with hardware 0261204527. Stage 1 is software only: the car keeps its standard turbo, injectors, intercooler and exhaust.
Stage 1 on the 230K 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 SLK 230K 2.0 carries the 230K engine, 193 hp and 280 Nm from the factory. On this engine, Stage 1 usually gives about 218 hp and 310 Nm (+25 hp, +30 Nm). Typical figures for a healthy engine: your car's own result depends on its condition, fuel and parts.
For this calibration of the MB SLK 230K 2.0 we sell the original and Stage 1, 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, 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 0261204527 is the number on the Bosch ECU's label.
