Weistec Engineering – Mercedes-Benz M113 4.3L ECU Tune – S430 / ML430 / CLK430 / C43 AMG

Description

Weistec Engineering ECU tune for the Mercedes-Benz S430, ML430, CLK430 and C43 AMG (2000-2005) with the NA 4.3L V8 (M113). Weistec’s crank figures put the tuned engine at 288 hp and 315 lb-ft, up from 269 hp and 295 lb-ft stock, from a recalibration of the factory ECU software.

Key Features:

• Up to +19 hp / +20 lb-ft: Weistec’s crank estimate of 288 hp and 315 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: 722.6 EGS52 TCU Upgrade, 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.
• Tuning method: Cypher Plus: flashed at home from your phone with a Weistec Cypher Plus.
