M177 E-Performance ECU Tune

Product Description

AMG paired the M177 twin-turbo V8 with a rear-axle-mounted electric motor as part of its P3 hybrid architecture, a plug-in system sophisticated enough to send electric drive independently to the rear wheels rather than simply assisting the combustion engine. It's the most power-dense application of the M177 Mercedes-AMG has ever built, combining the same hot-vee turbo placement, dry-sump lubrication, and flat-plane crank that define the standard M177 with a dedicated hybrid control system layered on top of it all.

Weistec's Calibration Department built a dedicated tune purely for the combustion side of this hybrid powertrain, a pure software recalibration that leaves the factory hybrid control logic, battery management, and electric motor completely untouched while keeping the M177's own knock protection, thermal management, and OEM diagnostics fully intact. Focused entirely on the combustion engine's contribution to the system, the tune delivers a meaningful gain in both power and torque over the factory calibration (individual gains may vary by vehicle), developed with the same validation rigor Weistec applies to its non-hybrid M177 work.
