Weistec Engineering – Mercedes-Benz M159 ECU Tune – SLS AMG

Description

Weistec Engineering ECU tune for the Mercedes-Benz SLS AMG (2010-2015) with the NA 6.2L V8 (M159). Weistec’s crank figures put the tuned engine at 606 hp and 514 lb-ft, up from 563 hp and 479 lb-ft stock, from a recalibration of the factory ECU software.

Key Features:

• Up to +43 hp / +35 lb-ft: Weistec’s crank estimate of 606 hp and 514 lb-ft, from Dynojet testing; real gains depend on fuel, conditions and supporting modifications.
• CARB EO D-691-3: W.1 is CARB-exempt and street legal in all 50 US states; W.2 is for competition use.
• Stage calibrations: W.1 (Stock Vehicle) and W.2 (Race Exhaust fitted), so the calibration matches the hardware on your car.
• Optional add-ons: Cypher Classic Handheld and SLS TCU Tune, each selectable when you order.
• Reflash of the factory ECU: the original module is recalibrated rather than replaced with a stand-alone or piggyback unit.
• What changes: improved throttle response, optimized fuel and spark and top speed limiter removed.

Fitment:

• Mercedes-Benz SLS AMG 2010-2015 (Black Series (C197), Coupe (C197), GT Coupe (C197), GT Roadster (R197), Roadster (R197)) – NA 6.2L V8 (M159)
