VR Tuned ECU Flash Tune Mercedes ML500 | ML550 4.7L Bi-Turbo V8 W166 408HP

The Mercedes ML500 | ML550 W166 is a far cry from a soccer mom SUV. The 4.7L Bi-Turbo V8 engine comes from Mercedes with 400 horsepower and just over 440FT/LBs of torque. Whats great about these Bi-Turbo Mercedes is how easily they can be tweaked to gain tons more performance. This SUV is already awesome in its power delivery and performance. Our ECU calibration takes your SUV from a already nimble driving machine to a powerful torque monster. The VR Tuned upgrade adds more horsepower over stock. Overall, the driving characteristics are vastly improved while providing you additional benefits that your SUV craves for. The biggest difference when you flash your SUV is the overall improvement of the power curve. Your SUV will have much better throttle response all the way to redline. Where the SUV is sluggish off the line, your newly flashed SUV picks up right away and pulls harder through the mid and top end RPM range.

How to Flash Your ECU?

• Use the Alientech Powergate 3+ handheld device. This device is a touchscreen module that lets you store your original and tuned files to easily flash between them. See Instructions Here.
• We can bench flash the ECU. To bench flash the ECU, you must remove it from your vehicle and send it to us. Once we receive the ECU, we will prepare the tune file and then ship it back to you for re-installation. We do not solder or modify the ECU board at all. All ECU tuning is done via bungy probes that have a needle tip to provide an electrical connection.
• Bring your vehicle to our facility where we can use our Master Cable to flash your vehicle.

For reference, this ECU is a Bosch MED17.7.1.
