ECU Tuning Process:How do I get my ECU tuned?
The M177 engine is a potent powerplant. Through rigorous testing, on both the street and dyno, the Weistec M177 ECU Upgrade reliably extracts massive gains in the mid range of the powerband as well as substantial gains in the top end making it a top performer in all driving situations

WEISTEC M177 ECU POWER
What does all this mean to you? More power, sharper throttle response, and a complete focus on the driver makes this the perfect addition to your AMG for a much more enjoyable experience for you.
Advertised gains are estimates of HP and Torque “at the engine” calculated from gains as measured on a Dynojet Dynamometer in ideal conditions and typically show the largest possible change. Actual gains are dependent on the following: Learn More about Crank HP Vs Wheel HP
Model – Manufacturers use the same engine in multiple model vehicles and often times they are in a different state of tune, for example: 2008 C63 and a 2008 CLK Black Series. Both have the same engine, but the C63 has 451hp while the CLK63 has 500hp. Naturally the C63 will show more gains as it starts at a lower level.
Model Year – Similar to above, as time progresses, Manufacturers tend to slightly increase power output via software from one year to the next or offer “Performance Packages” with increased power. The engines remain largely unaltered and as a result, final tuned output remains the same, while the gains are lower as the starting point is now higher.
Fuel – Fuel quality is HIGHLY important with performance vehicles. Low quality and/or low octane fuel will greatly impact engine output and potentially even engine health. Top tier brand premium fuels should always be used to achieve the best results possible.
Drivetrain – All wheel drive has higher drivetrain losses than rear wheel drive. This results in lower numbers when testing on a chassis dyno. Wheel/tire size and weight will also impact chassis dyno results
Weather/Conditions – Temperature, humidity, altitude, and air density all impact engine performance. Heat, high humidity, and thin air will all work towards reducing engine output
Engine Health – Higher miles tends to result in increased build up and lower compression which can and will impact engine output. Properly maintained engines will have better performance than abused or neglected engines.
Supporting modifications – The highest power levels require supporting modifications. Depending on the engine, this could mean forged internals, built transmission, upgraded fuel system, 110+ octane race fuel, etc.
