Part Number: ECU:54.253C.GLC43BI

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.

 

With the proprietary RENNtech ECU Tuning the C253 - GLC 43 AMG Coupe gains up to +25 HP and +42 LB-FT, based on power numbers measured by RENNtech. Please note that the Mercedes M276 engine performance when measured obtains higher numbers than rated from factory. The maximum power number reached with the RENNtech ECU Upgrade for the C253 - GLC 43 AMG Coupe is 400 HP and 440 LB-FT.

  • Mercedes M276 engine performance when measured obtains higher numbers than rated from the factory.
  • Power gains are calculated with stock numbers measured by RENNtech
  • Crank Performance Numbers are calculated with a 17% Drivetrain loss on 4MATIC vehicles.
