MERCEDES E63 / E63S W213 ECU REMAP

Custom Remap for the Mercedes-AMG E63 & E63S (W213) at MSL Performance

**If your vehicle is registered from mid 2021 onwards then your ECU has a strong chance of being locked from factory, if this is the case then we would need to send your ECU for unlocking prior to any tuning, please refer to the following link: ECU UNLOCKING**

Let's be honest, you already own the pinnacle of the super-saloon world. The W213 E63S is a technological masterpiece, a blend of executive luxury and all-wheel-drive supercar performance that defies physics. But have you ever planted your foot, felt that brutal acceleration, and sensed that deep down, the engineers designed the 4.0L Bi-Turbo V8 with even more in reserve? A sharper edge, a more savage top-end, a whole new stratosphere of performance waiting to be unlocked? You're right. There is.

Here at MSL Performance in Birmingham, we are specialists in AMG's latest and most advanced platforms. We don't believe in generic, off-the-shelf tunes. We are dedicated to the craft of custom remapping, connecting directly to your vehicle to create a bespoke software solution tailored to its specific needs. It's a perfect fit that unleashes the true potential of your E63, safely and reliably.

Find Your Perfect Level of Power

Every E63 owner has a different goal. That's why we've engineered a clear tuning path to help you achieve the exact level of performance you demand, from a breathtaking upgrade to an all-out assault on the tarmac.

Stage 1: The "Executive Supercar" Tune

This is for the driver who wants to elevate their E63S into the realm of true hypercar rivals, all on stock hardware. We meticulously recalibrate the engine and gearbox software to unleash a staggering new level of performance. The throttle response becomes telepathic, and the acceleration is transformed into an utterly relentless, awe-inspiring surge that pulls hard all the way to the redline.

• The Result: Up to the 700 bhp mark with an incredible 100 lb-ft of additional torque.
• What you need: Just your car! No extra parts are required.

Stage 2: The Ultimate Performance Package

Ready to push the boundaries of what a saloon can do? Stage 2 is where we unlock the V8's true voice and fury. By installing high-flow downpipes, we eliminate the biggest bottleneck in the exhaust system, allowing the twin turbos to breathe freely and work more efficiently. This upgrade allows our custom tune to deliver breath-taking ferocity, accompanied by a deep, aggressive V8 roar that announces your arrival with authority.

• The Result: Up to the 740 bhp mark.
• What you need: Downpipes (decat or sports cat) are essential.

The Final Unlock: CPC Module Tuning

For the ultimate pursuit of power, we go one step further. Modern AMGs are equipped with a Central Powertrain Controller (CPC) which acts as a master governor, often placing a final limit on the torque and power the engine can produce.

By performing a dedicated CPC tune in addition to our Stage 2 remap, we remove this final software barrier. This allows the engine, ECU, and high-flow downpipes to work in perfect, unrestricted harmony.

• The Result with CPC Tune: This unlocks the true potential of the Stage 2 package, achieving up to an astonishing 790 bhp.
