Weistec Engineering – Mercedes-Benz M264 ECU Tune

Description

Weistec Engineering ECU tune for the M264-powered Mercedes-Benz models (2018-2023) with the Turbocharged 2L I4 (M264). Weistec’s crank figures put the tuned engine at 281 hp and 313 lb-ft, up from 255 hp and 273 lb-ft stock, from a recalibration of the factory ECU software.

Key Features:

• Up to +26 hp / +40 lb-ft: Weistec’s crank estimate of 281 hp and 313 lb-ft, from Dynojet testing; real gains depend on fuel, conditions and supporting modifications.
• Stage calibrations: W.1 (Stock Vehicle) and W.2 (Race Exhaust fitted), so the calibration matches the hardware on your car.
• Optional add-ons: CPC Module (2019+) and 9 Speed TCU Tune (2019+), 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, increased boost and top speed limiter removed.
• Tuning method: Cypher Plus: flashed at home from your phone with a Weistec Cypher Plus.
