MP4 12C ECU Tune

Product Description
The MP4-12C is the car that brought McLaren back. It was the first all-new production McLaren built since the legendary F1 left showrooms, and the first car ever to wear the newly formed McLaren Automotive badge, which is a huge amount of history riding on one engine bay. That engine, the 3.8-liter M838T, is a genuinely special piece of engineering: a 90-degree, flat-plane-crank twin-turbo V8 developed with the UK's Ricardo, whose cylinder bore can be traced all the way back to a Nissan-derived block that TWR originally built for an IndyCar program that never even got to race. McLaren clearly believed in what they'd built, because they didn't sit still with it, bumping factory output from 592 PS to 625 PS and wrapping it all in the carbon-fiber MonoCell chassis that became the template every McLaren since has been built around.
Weistec's ECU calibration takes that already remarkable M838T and pushes it further, working entirely within the engine's own software architecture rather than bolting anything on top of it. Every factory protection McLaren engineered in, from knock detection to thermal management to OEM diagnostics, stays fully active and untouched. It's an OEM-level recalibration, built with the same rigor as a factory engineering program, and on the MP4-12C that means real numbers: a jump from 625 hp and 443 lb-ft to 730 hp and 652 lb-ft. This was the car that put McLaren back on the map. With Weistec's calibration behind it, it's operating on a whole different level.
