    F136 4.5L V8 ECU Tune

  • 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



The F136 is one of the great naturally aspirated V8 stories of the last two decades, a family Ferrari and Maserati engineered together starting in the early 2000s and kept refining across a run that spanned 4.2 to 4.7 liters. Ferrari's own versions carried a flat-plane crankshaft pulled straight from the brand's Formula 1 experience, giving them the high-revving, F1-inflected howl Ferrari is famous for, a deliberate contrast to the cross-plane crank in the Maserati and Alfa Romeo versions of the same family, tuned instead for smooth, confident low-end torque. It reached its peak in the final, largest 4.5-liter form built for the 458 Italia: 562 factory horsepower, a redline pushing toward 9,000 rpm, and a trophy case full of International Engine of the Year awards that makes it one of the most decorated naturally aspirated V8s ever built.

An engine this celebrated deserves a calibration that matches its pedigree, and that's exactly what Weistec built for it: a pure software recalibration, engineered to the same validation rigor Ferrari itself used when this V8 left Maranello. It works inside the factory's own knock protection, thermal limits, and OBD diagnostics rather than around them, unlocking real performance the factory left on the table and taking the 4.5L V8 from 570 to 600 horsepower and 398 to 425 lb-ft of torque, a genuinely another-level result for hardware this good.

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.

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.
