RENNtech Intermediate ECU Upgrade | 574 HP/612LB-FT | 4.0L V8 BiTurbo | M177 | Mercedes-Benz C63 AMG / C63S AMG Sedan 2016-2023

RENNtech HHT (hand held tuner) allows you the unlimited ability to switch between tuned and stock ECU programming and requires no ECU removal!

Our proprietary tuning module stores both the RENNtech tuned file and your vehicles stock file. The module plugs directly into the OBD2 port and delivers the file you choose directly to the ECU. Programming takes only a few minutes and the vehicle can be reflashed at any time as many times as you wish.

RENNtech has been at the forefront of ECU tuning since electronic engine management started to show up in vehicles during the mid 1980s! Our experience, countless hours of in-house research, development and exhaustive testing ensure that our proprietary ECU upgrade offers incredible performance gains and rock solid daily driver reliability.

RENNtech tuning software for Mercedes offers significant gains in horsepower and torque across the vehicle's entire power band. By modifying ignition timing and throttle mapping, optimizing air-to-fuel ratios, increasing the engine's rev limiter and modifying boost mapping for turbo-charged vehicles, RENNtech performance software unleashes the true potential of your Mercedes.

Our intermediate level ECU upgrade offers huge gains in performance across the entire RPM range without sacrificing around town comfort or daily driver reliability.

This is ideal for customers who want increased performance in their daily driver without worry of extra strain on driveline components or for areas and countries with extreme altitudes, temperatures or fuel quality concerns.Â

This is a slight reduction from our standard tune but still offers white knuckle performance at one of the most affordable price points in the tuning market.

With the intermediate RENNtech ECU Tuning the W205 - C63 AMG 4MATIC+ gains up to +48 HP and +80LB-FT, based on power numbers measured by RENNtech. Please note that the Mercedes M177 engine performance when measured, obtains higher numbers than rated from factory. The maximum power number reached with the intermediate RENNtech ECU Upgrade for the C63 and C 63 S AMG is 574 HP and 612 LB-FT.

    Notes:

    • RENNtech stock power numbers are measured with the C 63 AMG. Tune is compatible with C 63 AMG and C 63 S AMG. Maximum power numbers are for both, S and non-S models.
    • We have found the M177 engine stock performance numbers vary from the baseline figures claimed by Mercedes-Benz. We typically see higher baseline numbers than claimed by the factory.
    • Power gains are calculated based on stock numbers measured by RENNtech. Crank Performance Numbers are calculated with a 16% Drivetrain loss on 4MATIC+ vehicles.
    • Numbers published by MBUSA are an average over a 750rpm range for HP and a 2,750rpm range for TQ. Power gains are calculated based on the peak stock performance measured by RENNtech.
    • Our numbers will be dependent on conditions and fuel quality. 93+ Octane gasoline is mandatory with this Performance Upgrade.
    • States known for poor fuel quality have to be supplied with a lower power setup
