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

Weistec specializes in engineered performance solutions with designs that match and often exceed OEM levels of precision and quality. Our ECU Tune for Lamborghini's 6.5L V12 Hybrid (L545) is designed to enhance the vehicle's characteristics without compromising the drivability or reliability of the vehicle. What does all this mean to you? More power, sharper throttle response, and a complete focus on the driver makes this the perfect addition to your Lamborghini Revuelto for a much more enjoyable experience. For more information please feel free to contact our performance specialists via phone or email at sales@weistec.com.

IMPORTANT NOTE: This ECU is locked by the manufacturer and requires a paid ECU Unlock before tuning. This tune requires a bench flash and is available by mailing in your vehicle's ECU to us or through a Cypher Pro Dealer -- it is not available as a self-install (no Cypher Plus / Cypher Classic option). If you have any questions please visit our Support Page to reach out to our performance specialists.

Understanding CPC & TCU Tunes

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.

What is an ECU Unlock?

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.

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.).
Product may not be emissions compliant. Check local laws prior to installation.
Always use a battery charger during programming.
Newer vehicles may require an ECU Unlock before tuning is possible.
