ECU Upgrade for Mercedes C-class C350 W204 MY 08-11
DESCRIPTION
ECU Tuning Group’s (ETG) proprietary software for the Mercedes C-class C350 W204 MY 08-11 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, we can make adjustments to engine parameters, such as spark timing, fuel injection, and/or boost (if applicable) to increase the output of the vehicle’s motor.
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.
HIGHLIGHTS

– Reprogram Throttle Maps for Improved Throttle Response
– Reprogram Transmission Maps for Quicker Shifts
– Raise Rev Limiter
– Remove Speed Governor
– Undetectable at Dealership (most vehicles)
– Vehicle Can Be Put Back to ‘Stock’ Upon Request
– Complimentary Re-flashing of ECU included, if Dealer Reprograms ECU
– Bench Flash recommended, but Piggyback Performance Module Optional (operates independent of ECU)

*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.
