The original factory software in your BMW E60 M5 and E63 M6 has been engineered for emissions compliance and mass market appeal, leaving performance as "good enough". BMW deliberately de-tunes the car for lower octane that we have in the US even when they "require" premium fuel. This naturally leaves some room for improvement when the ignition and timing maps are not optimized for 91+ octane fuel. We tune the ignition, camshaft, and VANOS values to optimize them for better fuel. We also adjust the fuel maps to match the more aggressive timing. Our software produces more horsepower (+27hp) and torque (+21ft-lbs) and a smoother-running engine. We don't just tune for full throttle either - there is more torque available in the mid-RPM as well! Throttle response is also improved.
Stage 1 software is for a stock engine or with a basic cold-air intake. Other stages are also available including full race with catalytic converters and the air pump removed.
We have been partners with Epic Motorsports for BMW performance software for over ten years. They are one of the very best BMW ECU tuners in North America. Our custom performance tune for the M5/M6 combines these years of BMW performance tuning, racing and track events, and ECU tuning into this fantastic S85 software upgrade.
Our software is installed via a D-CAN cable (included) and your Windows laptop (compatible with XP, Win7, Win8, and Win10). The D-CAN cable is included at this price. Read and email your stock file and a tuned file will be returned to you. This is better than off-the-shelf tunes that never look at your original software.
Notice of Emissions Non-Compliance. This software was developed and tuned on vehicles that retained all emissions controls. It is intended for vehicles with stock and fully functional emissions equipment. However, it has not been submitted nor tested for approval in California. Therefore, it is not legal for installation or use in California on any pollution-controlled motor vehicle. Some suppliers will not ship to certain states, requiring extra delivery time. We will advise you of any delays. Not legal for installation or use on any pollution controlled motor vehicle in any state, province, or jurisdiction governed by, or which has adopted, CARB or EPA regulations.
