    M159 ECU Tune

  • 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

    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.

ECU Tuning Process: How do I get my ECU tuned?

When it comes to upgrading the 6.2L M159 engine that powers the SLS Black Series, no one does it better than Weistec Engineering. Our SLS Black Series ECU upgrade provides peak gains of nearly 30hp at the wheels as well as improving the engine's long power band on an otherwise stock car.

CARB EO# D-691-3

When our SLS Black Series ECU upgrade is paired with long tube headers, peak gains are nearly 80hp at the wheels with substantial gains throughout the entire power band and improved throttle response.

600 WHP, SLS Black Series Dyno, Weistec Tune and Headers on 91 Octane!

 

We have created a strong yet reliable tuning solution that utilizes the same calibration technology that has been applied to our Supercharger System. With a keen understanding for optimal running conditions for the SLS Black Series, we have revised many features of the ECU which creates up to an astounding 600 horsepower to the wheels on 91 octane!
