ETG ECU Upgrade | CLS 63 AMG S 4MATIC Biturbo C218 | M157 Engine | 710 HP & 783 LB-FT
DESCRIPTION
ETG’s proprietary software for the CLS 63 S AMG 4MATIC Biturbo maximizes vehicle performance, without compromising safety, reliability, or comfort.
ECU tuning refers to rewriting or remapping the software in your vehicle’s Electronic Control Unit (ECU) — sometimes referred to as an Electronic or Engine Control Module (ECM) — to improve the vehicle’s performance and/or responsiveness. The manufacturer generally uses conservative maps in the ECU to allow for slight variations across motors, poor fuel quality, and inadequate maintenance or neglect by owners.
By uploading new software to the ECU through the vehicle’s OBD port (in some cases, bench flashing the ECU/ECM or adding a separate Performance Module), we can make adjustments to spark timing, fuel injection, and boost (turbocharged vehicles).
On most vehicles, we will also adjust the electronic throttle control (drive-by-wire) maps for better throttle response, transmission maps for quicker shifts, raise the rev limiter, and remove the speed governor.

*Installation prices vary with vehicle (e.g., supercharged), product type (flash vs. module) and location. In some cases, it is best that we bench flash the ECU, so the ECU should be shipped to us via overnight delivery. Alternately, we can come to your home or office, remove the ECU, bench flash, and then return to reinstall the part.
**Performance gains may vary based on temperature, climate conditions, and fuel quality.
