The Eaton blower on an M111 is geared directly to the crank, so a calibration can sharpen ignition timing, fuelling and throttle mapping, but it cannot make the supercharger move more air. On this platform the pulley is the bigger lever. Fit a reduction pulley and recalibrate around it and the two together are worth far more than either on its own — tell us if one is going on and we will write the file for it from the start rather than tuning the car twice.\u003c\/p\u003e\n\n\u003ch3\u003eWhat the Tune Delivers\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStronger mid-range torque\u003c\/strong\u003e — where a supercharged four actually lives in street driving\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSharper throttle response\u003c\/strong\u003e — less pedal lag off idle and out of corners\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCalibrated around your hardware\u003c\/strong\u003e — pulley, intake, exhaust, injectors, whatever is already on the car\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFactory safeguards retained\u003c\/strong\u003e — knock control and thermal limits stay active\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eVehicle Compatibility\u003c\/h3\u003e\n\u003cp\u003eThis calibration is for the \u003cstrong\u003eM111 supercharged\u003c\/strong\u003e engine — both the 2.3L and the 2.0L Kompressor.\u003c\/p\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eChassis\u003c\/th\u003e\n\u003cth\u003eYears\u003c\/th\u003e\n\u003cth\u003eEngine\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSLK230 Kompressor\u003c\/td\u003e\n\u003ctd\u003eR170\u003c\/td\u003e\n\u003ctd\u003e1997–2004\u003c\/td\u003e\n\u003ctd\u003eM111 2.3L supercharged\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eC230 Kompressor\u003c\/td\u003e\n\u003ctd\u003eW202\u003c\/td\u003e\n\u003ctd\u003e1997–2000\u003c\/td\u003e\n\u003ctd\u003eM111 2.3L supercharged\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eC230 Kompressor Sports Coupe\u003c\/td\u003e\n\u003ctd\u003eCL203\u003c\/td\u003e\n\u003ctd\u003e2002–2003\u003c\/td\u003e\n\u003ctd\u003eM111 2.3L supercharged\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eTwo Things to Check Before You Order\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhich engine you have.\u003c\/strong\u003e The C230 Kompressor was sold with two unrelated engines. The early cars are M111; the Sports Coupe moved to the M271 1.8L around the 2003 model year and the sedan and wagon followed for 2004. Displacement is what decides it — 2.3L is M111, 1.8L is M271. Every R170 SLK is M111, whatever you may have read; the M271 did not arrive in the SLK until the R171 in 2004. Running the 1.8L? \u003ca href=\"\/products\/m271-1-8l-kompressor-custom-ecu-tuning-c230-slk200\"\u003eUse the M271 tune instead\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhich ECU you have.\u003c\/strong\u003e Later M111 cars use a Siemens SIM4LE, which reads and writes cleanly. Earlier cars run different engine management and are not always supported.

These cars are twenty years old and more, so mechanical condition matters: a calibration will not mask a slipping supercharger, a tired MAF or a vacuum leak. Figures above are typical, not guaranteed, and vary with fuel quality, ambient conditions and the health of the engine.\u003c\/p\u003e","brand":"BenzUnited Parts","offers":[{"title":"Default Title","offer_id":47275510235311,"sku":"BU-M111K-TUNE","price":700.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0631\/8718\/9935\/files\/f05683101d6b1e113c194c838973f949.jpg?v=1785665838","url":"https:\/\/benzunitedparts.com\/products\/m111-kompressor-custom-ecu-tuning-slk230-slk200-c230","provider":"BenzUnited Parts","version":"1.0","type":"link"}
