Weistec Engineering – Mercedes-Benz M272 3.0L ECU Tune

Description

Weistec Engineering ECU tune for the M272-powered Mercedes-Benz models (2005-2011) with the 3.0L V6 (M272). Weistec’s crank figures put the tuned engine at 255 hp and 247 lb-ft, up from 228 hp and 221 lb-ft stock, from a recalibration of the factory ECU software.

Key Features:

• Up to +27 hp / +26 lb-ft: Weistec’s crank estimate of 255 hp and 247 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: Cypher Classic Handheld, 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: top speed limiter removed, improved throttle response and optimized fuel and spark.
• Tuning method: Cypher Plus: flashed at home from your phone with a Weistec Cypher Plus.
