Weistec Engineering – Mercedes-Benz M133 ECU Tune – GLA45 AMG / A45 AMG / CLA45 AMG

Description

Weistec Engineering ECU tune for the Mercedes-Benz GLA45 AMG, A45 AMG and CLA45 AMG (2013-2019) with the Turbocharged 2L I4 (M133). Weistec’s crank figures put the tuned engine at 419 hp and 504 lb-ft, up from 355 hp and 332 lb-ft stock, from a recalibration of the factory ECU software.

Key Features:

• Up to +64 hp / +172 lb-ft: Weistec’s crank estimate of 419 hp and 504 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: 7G DCT 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, increased boost and top speed limiter removed.
• Tuning method: Cypher Plus: flashed at home from your phone with a Weistec Cypher Plus.
