Mercedes Benz SL550 ECU Tune

Tuned by Alex Gintani himself, Gintani Tuning’s ECU Software is guaranteed to give you more horsepower, torque, and a more exhilarating driving experience by delivering usable power through improved throttle response and torque management. With additional ft. lbs. of torque through the mid-range, acceleration out of your favorite corner and onto the straight is noticeably quicker throughout the rev range. Gintani saves your stock/factory ECU settings so that you can revert your vehicle back to stock settings at any time. 

Tuning Methods:

Depending on the current update of your vehicle's ECU, one of the two tuning methods will be used...

OBD Tune

OBD tunes allow customers to simply plug and upgrade their ECU. We will ship you a Gintani cable along with instructions

Bench Flash

Requires ECU to be mailed in.

This upgrade requires you to send us your ECU for re-programming. You will be emailed a download link with detailed instructions after adding this to your cart and checking out.

You must fill out and include a copy of the ECU Information form along with your ECU upon sending it in. Please contact us if you need to send the form in any other manner.

Gintani saves your stock/factory ECU settings so that you can revert your vehicle back to stock settings at any time.

Shipping Details For Bench Flash

Shipping costs for sending an ECU to and from Gintani is the responsibility of the purchaser. You will be charged return shipping at checkout.  The ECU will be tuned the same day it is received and Gintani will then ship back the ECU using whatever method it was shipped in with.
