Power gain Up To
+50 HP

Torque gain Up To
+50 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

The L545 doesn't just follow the Aventador's V12, it redefines what a Lamborghini flagship engine can be. This is an all-new 6.5-liter unit built specifically for the Revuelto, and on its own it's already Lamborghini's lightest and most powerful 12-cylinder ever, just 218 kg and putting out 825 PS by itself before anything else gets added. Then Lamborghini adds three electric motors on top of it: a pair of axial-flux units on the front axle plus a third radial-flux motor integrated right at the transmission, all fed by a 3.8 kWh battery pack. That combination makes the Revuelto Lamborghini's first plug-in hybrid HPEV, and combined, it's the most powerful production Lamborghini the brand has ever built. This is a genuinely new kind of Lamborghini flagship, and it earns that title.

Weistec's calibration meets that engineering on its own level, recalibrating the V12's engine control software and building directly on top of the factory's combustion-side tuning, with every one of the car's protections and diagnostics left exactly as the factory built them. Because the Revuelto's headline output is a total system figure, the gain is best measured the same way, and it's a real one: roughly 50 additional horsepower and 50 lb-ft of torque at the system level over stock, unlocked by a calibration held to the same rigor as the factory's own engineering. Already the most powerful Lamborghini ever made, and Weistec makes it hit harder still.

How Do You Get Your Lamborghini Revuelto ECU Tune Tuned?

Follow these steps — this is what your specific vehicle needs and supports.

Unlock Check

This ECU requires an unlock first

Modern ECUs are often locked down, especially after a dealer software update, which can block bench flashing or OBD flashing. Our ECU Unlock Service removes those restrictions, is done per ECU, and stays active through most future dealer updates as long as the bootloader isn't overwritten.

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.
