Topic: 1/4 mile testing the Mercedes-Benz E63S AMG (w213) (equipped with AMR Performance ECU Software Upgrade)
1/4 mile testing the Mercedes-Benz E63S AMG (w213) is not hard to do in stock form. However, when equipped with the AMR Performance ECU Software Upgrade (tune), the enhanced torque curve due to optimizing the vehicle’s potential makes it a little tricky. The enhanced torque comes in hard and causes all 4-wheels to spin. This article is dedicated to help you dial in your vehicle in a controlled insured professional environment.
This advice for a better “E.T.” is all dependent on track conditions, weather, weight of the vehicle, driver, octane, amount of fuel in the tank, and other factors outside of the vehicle’s power. Though we enhanced the power of the vehicle, the rest is up to the conditions, vehicle and driver!
Tires: If your vehicle is running the stock Michelin Pilot Sport tires (given to you from the factory/oem when purchasing the vehicle). You may see some tire spin when launching the vehicle. If this occurs, start by lowering your tire pressure. We recommend going as low as, but NOT passing, 30psi of air pressure. *Note: After 1/4 mile testing is completed, pleasure fill air pressure back to its appropriate rating as we do not recommend driving around with 30psi.
Temperature: In order to put the vehicle into “Race Mode“, you will need to have the vehicle’s “Engine Oil” and “Gear/Trans Oil” up to operating temperatures. To see this, go into your “Dash Display” and select the “AMG Dash“. Scroll through the dash options until you see the “Oil Temp” display. This will appear on the left side of the dashboard. When the vehicle is warming up, you will notice your oil temps are a “blue” color. Once the “Engine Oil Temp” reaches above 150 degrees it will change color to “white“. The “Gear/Trans Oil Temp” will do the same once it reaches above 122 degrees. When both of these temperatures displays are in “white“, you can now move forward to putting the vehicle into “Race Mode”
R-Mode & Traction Control: Put your vehicle into “R-Mode”. Once in this mode, hold down the traction control button located on the center console. Hold down the button until you see the traction control indicator status “OFF”. This will be seen on the dashboard.
Suspension: This will also depend on track conditions as well as how much “grip” the vehicle’s tires are having. If you need the vehicle to have more of a squat, we recommend setting the suspension to stock. Which would mean pressing the suspension button twice until both read indicators are turned off.
Launch Control: Factory launch control “DEFAULT” settings are set to 3200-3500rpm. Enable launch control and raise this to 4300-4500rpm.
Launching: With the vehicle in “R-Mode” and the “Traction Control Disengaged/OFF“, you are now ready to launch the vehicle. Firmly hold down the break pedal and push the throttle pedal to the floor (wide-open-throttle). You will the vehicle’s RPM go above 3500rpm but not passing 4000rpm. You will also hear the turbos building pressure. *Note: you do not want to do stay in launch control for a excessive amount of time as this can cause damage. We recommend a couple seconds to properly build boost and launch the vehicle. If your vehicle’s tires have road/sand debris, we recommend doing a small launch in the “water prep” / “burn out” area before moving forward to the starting line
Shifting: Due to your “NEW” power band caused by the software upgrade, you will “launch the vehicle”, once the vehicle is moving, you will notice it will shift on its own from 1st gear to 2nd gear. Once the vehicle shifts to third gear, you want to watch your “TACHOMETER” and hit the “right side (+) upshift paddle” when the vehicle reaches 6000-6200rpm. Continue to do this throughout the RPM band.Since your vehicle is not permanently set to “MANUAL” mode, it will automatically go back to “AUTO” shifting on its own.
*** Note: Every driver is different. We all have different reaction times and way(s) we drive our vehicle(s). 1/4 Mile is testing is about how quickly the vehicle can get from point “A” to point “B”. Some, with experience and improved driving techniques will see better E.T. and MPH times then others. If you do not get the time(s) you hoped for the first couple time(s) out, do not get discouraged! Practice does make perfect!
