RENNtech has been at the forefront of ECU tuning since electronic engine management started to show up in vehicles during the mid 1980s! Their experience, countless hours of in-house research, development and exhaustive testing ensure that their proprietary ECU upgrade offers incredible performance gains and rock solid daily driver reliability.

With the release of the Vantage V8, Aston Martin started their collaboration with Mercedes-Benz. The newest V8 models from the British car manufacturer are powered by one of Mercedes-Benz most powerful and successful engines, the M177. Developed by Mercedes-AMG this 4.0L V8 BiTurbo is used in a variety of models, including the AMG GT Family, E 63 AMG, S 63 AMG, C 63 AMG and many more. The experience gained on the Mercedes-AMG helped RENNtech to develop one of the most powerful ECU Upgrades for the Aston Martin on the market.

RENNtech tuning software for Mercedes offers significant gains in horsepower and torque across the vehicle’s entire power band. By modifying ignition timing and throttle mapping, optimizing air-to-fuel ratios, increasing the engine’s rev limiter and modifying boost mapping for turbo-charged vehicles, RENNtech performance software unleashes the true potential of your Aston Martin.

With the proprietary RENNtech ECU Tuning the Aston Martin Vantage V8 gains up to +85 HP and +89 LB-FT, based on power numbers measured by RENNtech. Please note that the Mercedes M177 engine performance when measured, obtains higher numbers than rated from factory. The maximum power number reached with the RENNtech ECU Upgrade for the Aston Martin Vantage V8 is 615 HP and 645 LB-FT.
