RENNtech ECU+ Upgrade | Aston Martin | V8 Vantage | 615 HP/645 LB-FT | 4.0L V8 BiTurbo | M177 | MY2018+

RENNtech has been at the forefront of ECU tuning since electronic engine management started to show up in vehicles during the mid 1980s! Our experience, countless hours of in-house research, development and exhaustive testing ensure that our 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.

Notes:

• We have found the M177 engine stock performance numbers vary from the baseline figures claimed by Aston Martin. We typically see higher baseline numbers than claimed by the factory.
• Power gains are calculated based on stock numbers measured by RENNtech. Crank Performance Numbers are calculated with a 12% Drivetrain loss on RWD vehicles.
• Numbers published by Aston Martin are an average over a 750rpm range for HP and a 2,000rpm range for TQ. Power gains are calculated based on the peak stock performance measured by RENNtech.
• Our numbers will be dependent on conditions and fuel quality. 93+ Octane gasoline is mandatory with this Performance Upgrade.
• States known for poor fuel quality have to be supplied with a lower power setup. Please call for details and Race fuel options +1-561-845-7888.
