      Aston V12 5.2 ECU Tune

    • Power gain Up To

      +157 HP

      Torque gain Up To

      +218 TQ

      Advertised gains are estimates of HP and Torque “at the engine” calculated from gains as measured on a Dynojet Dynamometer in ideal conditions and typically show the largest possible change.  Actual gains are dependent on the following: Learn More about Crank HP Vs Wheel HP

      Model – Manufacturers use the same engine in multiple model vehicles and often times they are in a different state of tune, for example: 2008 C63 and a 2008 CLK Black Series.  Both have the same engine, but the C63 has 451hp while the CLK63 has 500hp.  Naturally the C63 will show more gains as it starts at a lower level.

      Model Year – Similar to above, as time progresses, Manufacturers tend to slightly increase power output via software from one year to the next or offer “Performance Packages” with increased power.  The engines remain largely unaltered and as a result, final tuned output remains the same, while the gains are lower as the starting point is now higher.

      Fuel – Fuel quality is HIGHLY important with performance vehicles.  Low quality and/or low octane fuel will greatly impact engine output and potentially even engine health.  Top tier brand premium fuels should always be used to achieve the best results possible.

      Drivetrain – All wheel drive has higher drivetrain losses than rear wheel drive.  This results in lower numbers when testing on a chassis dyno.  Wheel/tire size and weight will also impact chassis dyno results

      Weather/Conditions – Temperature, humidity, altitude, and air density all impact engine performance.  Heat, high humidity, and thin air will all work towards reducing engine output

      Engine Health – Higher miles tends to result in increased build up and lower compression which can and will impact engine output.  Properly maintained engines will have better performance than abused or neglected engines.

      Supporting modifications – The highest power levels require supporting modifications.  Depending on the engine, this could mean forged internals, built transmission, upgraded fuel system, 110+ octane race fuel, etc.

    Product Description


    Aston Martin DB11 V12

    The AE31 marks the moment Aston Martin went all-in on forced induction, and it did it in spectacular fashion. This is the brand's first production twin-turbocharged V12, and it's not an evolution of the naturally aspirated 5.9L it replaced, it's a ground-up, all-new 5.2-liter design, built around a quad-cam, all-alloy block engineered from day one specifically for boost. It debuted in the DB11 at 600 horsepower and was worked progressively harder across the range from there, culminating in the DBS Superleggera's flagship tune of 715 horsepower and 900 Nm. Turbocharging didn't dilute Aston's V12 heritage, it became the foundation of its entire modern era.

    Weistec's ECU calibration works within that same factory turbo hardware, the same turbochargers, the same fueling system, the same OEM knock and thermal protections, recalibrating the software with the same rigor as Aston's own tuning to unlock what that turbocharged architecture was built for all along. And because the factory turbos already have real headroom on tap, the payoff is enormous: roughly 157 horsepower and 218 lb-ft of torque over stock in Weistec's own testing. The AE31 already redefined what an Aston V12 could be. This calibration is where it finally gets to show it.

    Complete The Upgrade

    An ECU tune alone won't remove all factory limits or fix how power reaches the ground. Add these to round out the upgrade with no limitations.
    Read the full CPC & TCU breakdown →

    What is a CPC module?

    The CPC (Central Powertrain Control) is a separate control unit that manages things like the active exhaust valves, radiator fan, intercooler pumps, and speed limiter. On many newer Mercedes-Benz vehicles, it also houses torque limiters that can hold back an ECU tune from reaching its full potential.

    What is a TCU tune?

    A TCU (transmission control unit) tune delivers faster, firmer shifts with higher line pressure, reducing clutch slip and increasing the transmission's torque capacity. It's a worthwhile upgrade on its own, or paired with an ECU tune for a fully sorted powertrain.

    Good to Know

    • This is a reflash of your original module, not a stand-alone unit.
    • Power gains vary by vehicle, modifications, fuel, and operating conditions (ambient temperature, altitude, etc.).
    • New or upgraded spark plugs are always recommended when tuning.
    • Product may not be emissions compliant. Check local laws prior to installation.
    • Always use a battery charger during programming.
