E46 325, 330 with C38 blower AA Supercharged Cars Operating Instructions

Always allow your engine and supercharger to warm up for at least one minute before placing the car in gear. In colder weather (below 50 degrees Fahrenheit), we recommend at least two-to-three minutes of warm-up time. Always use the best fuel (93 octane) available. If 91 octane is the only available fuel, add an octane booster if you detect any knocking. Active Autowerke calibrates the software to operate on 91 octane, but some cars may experience slight knocking or detonation. Excessive knocking will damage the motor, so pay close attention to any hint of knocking.
