BM3 tuning is not stable and may lead to engine damage. Below are specific instructions regarding BM3 tuning: 1. TU Engines: If the engine is a B48TU, it is not recommended to install BM3 tuning, as the air-cooling system of the B48TU is inferior in performance compared to later water-cooled versions. 2. Water-Cooled Engines: BM3 tuning can increase power by 46%, which means the engine generates more heat. Without modifications to the cooling system, engine damage may occur. For water-cooled B48 engines, installing a Stage 1 BM3 tuning is relatively safer.

What Causes BMW Engine to Shake When Idling with AC On?

BMW engine shaking when the AC is on can be attributed to the following reasons: 1. Excessive carbon buildup in the throttle body and intake manifold: This alters the air passage cross-sectional area, preventing the control unit from precisely regulating idle air intake. This results in either overly rich or lean air-fuel mixture, causing incomplete combustion and subsequent vibration. 2. Faulty spark plugs: Weak sparks from individual malfunctioning spark plugs can compromise engine performance, leading to "misfire" symptoms and unstable idling. 3. Fuel pressure issues: Insufficient fuel pressure leads to poor fuel atomization from injectors, with fuel spraying in streams or even dripping in severe cases. Reduced fuel injection causes excessively lean mixture.
