The BMW S58 engine — powering the G87 M2, G80 M3, and G82 M4 — is the first production petrol engine to feature centrally controllable piston cooling. This is not marketing language. It is an engineering distinction that separates the S58 from every other inline-six BMW has built, including the B58TU, and it has direct implications for anyone tuning or building these engines for higher output. At YPG Motorsport, we calibrate S58 engines pushing well beyond factory power targets. Understanding piston cooling control is not optional at those levels — it is the difference between an engine that survives sustained...

What Is CAMTRONIC and How Does It Work on the M177? Every M177-powered AMG — the C63, E63, AMG GT, GT 63, and GLC 63 — uses a cylinder-deactivation system Mercedes-Benz calls CAMTRONIC. Under light loads, four of the engine’s eight cylinders shut down to cut fuel consumption. The moment you press the throttle, all eight fire again in milliseconds. For tuners, CAMTRONIC matters because it directly affects camshaft behaviour, ECU calibration tables, and exhaust-gas temperature management. Whether you are running a Stage 1 ECU flash or building a 900 HP monster, you need to understand what this system does...
