Senna ECU Tune

Product Description

The Senna is McLaren with absolutely nothing held back. Named for Ayrton Senna and built with almost no concession to comfort or everyday usability, it's the lightest McLaren road car since the F1 itself at just 1,198 kg. Its version of the M840T V8 was, at launch, the most powerful internal-combustion engine McLaren had ever put in a road car, making 789 hp with a power-to-weight figure that outran everything else in the lineup. Only 500 were ever built, and every panel and surface on the car was shaped almost entirely by aerodynamics and lap time, not styling.

Weistec's ECU calibration for the Senna is a recalibration of that factory M840T's own software. It works within McLaren's own engineering to extract more from hardware that was already built for extreme use. Knock protection, thermal management, and every OEM diagnostic function stay exactly as the factory designed them. Built to OEM-level standards, it takes this Senna from a factory 789 hp and 590 lb-ft to 990 hp and 730 lb-ft, pushing a car McLaren built with no compromises even further past where the factory stopped.
