C300 Mercedes Benz Tuning: 2016 Mercedes-Benz Turbo 4MATIC
Tuning a Mercedes-Benz C300
Just last week we had the opportunity to tune a Mercedes-Benz C300. This Mercedes Benz tuning of a C300 4MATIC comes nicely equipped with the M274 4-Cylinder Turbo Engine that is surprisingly powerful and efficient. It’s quite impressive actually. The cars styling will also impress most Mercedes-Benz fans. It’s bold and really looks like the sport vehicle we’ve come to expect.
So the car is nice and the M274 is no slouch when it comes to power. The C300 Turbo boasts a whopping 241HP and 273 LB-FT of torque. That really is impressive for a 4-cylinder. We took it for a test drive and while we were impressed, we felt that we could improve it dramatically. While driving, we noticed immediately that there is a lag between the time you press the accelerator and the time that the turbo kicks in. When you’re driving in traffic, merging onto a freeway or just feel the need to put your foot down, you want to feel that power immediately and that was just the tip of the iceberg.
Starting the Process
We took the Mercedes C300 back to the shop and started with the tune. While this is not our first C-Class tune, it was our first on the 2016. Like all Mercedes Benz tuning starts, we took the ECU (Electronic Control Unit) out and carefully opened it revealing the maze of circuit boards. The first order of business is to verify that the ECU is in working order and it’s very rare to come across one that’s not but we always like to err on the side of caution. The next order of business is to read the existing ECU programming with our specialized software. Once read, we always save the original ECU programming to our redundant systems just in case the owner ever needed to return to the stock values for whatever reason.
Now that we have the ECU programming backed up, we make a working copy and that’s where we start our magic. Years of experience and testing give us the ability to draw the most out of these engines without ever crossing the safe limit marker. We just make the car more efficient and that’s what Performance Perfect ECU Tuning is all about.
Now that we’ve built our file, it’s time to merge and write the file to the ECU. Our Mercedes Benz Tuning specialized race software and equipment make this a fairly easy process. Within a few minutes all our previous work is written to the ECU. We reinstall the ECU into the car and close the hood. Next step is actually our favorite… It’s time for the test drive!
Performance Perfect Tuned and Ready to Go
Now the Performance Perfect Tuned car has approximately 260HP and 300 LB-FT of torque and boy does it show! Driving in Sports Plus Mode, our immediate impression is that the turbo lag on the stock ECU is virtually eliminated. The turbo kicks in almost immediately and the additional boost from the turbo is quite evident. Simply put, the C300 4-Cylinder Turbo is immediately more responsive and the driver can feel the increase in power. This is true throughout the gearing whether starting from a dead stop or putting your foot down and accelerating away from 40MPH. Responsive and powerful, we’ve unleashed the potential. Ironically, we also expect an increase in gas mileage. This particular vehicle averages 23.2 miles per gallon and we fully expect a 5-8% increase. The car is just more efficient.
