Weistec Engineering – McLaren 600LT ECU Tune

Description

Weistec Engineering ECU tune for the McLaren 600LT (2019-2021) with the Twin Turbo 3.8L V8 (M838TE). Weistec’s crank figures put the tuned engine at 730 hp and 652 lb-ft, up from 592 hp and 457 lb-ft stock, from a recalibration of the factory ECU software.

Key Features:

• Up to +138 hp / +195 lb-ft: Weistec’s crank estimate of 730 hp and 652 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: One Step Colder Spark Plug Set, 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 and optimized fuel, spark and boost.
• Tuning method: Mail In: the module is removed and mailed to Weistec for programming.

Fitment:

• McLaren 600LT 2019-2021 (Base, Spider) – Twin Turbo 3.8L V8 (M838TE)
