Product Description

RENNtech M157 Biturbo ECU Upgrades are TÜV approved!

Our proprietary ECU upgrade for the Mercedes M157 engine offers huge gains in performance across the entire RPM range without sacrificing around town comfort or daily driver reliability.

Our ECU tune offers the biggest performance gains on the market with our dyno results increasing performance from 556 HP and 550 lb/ft torque, to an astonishing 669 HP and 734 lb/ft at the crank! This allows the CLS 63 to run the quarter mile on D.O.T. street tires in an impressive 11.3 seconds at 125 mph with 0-60 mph coming in a mere 3.4 seconds.

Equipped with drag radials on the CLS we were able to achieve an even more impressive quarter mile time. The CLS was able to rocket down the drag strip; clocking a quarter mile time of 10.9 seconds @ 129 mph with 0-60 mph coming in 3.2 seconds!

CLS 63 (C218) Stock Performance (Without Performance Package):

  • 518 HP @ 5500 RPM; 516 LB-FT @ 4800 RPM

CLS 63 (C218) Stock Performance (With Performance Package):

  • 550 HP @ 5500 RPM; 590 LB-FT @ 4800 RPM
  • Note: We have found the new M157 engine stock performance numbers vary from the baseline figures claimed by Mercedes Benz. We typically see slightly higher baseline numbers than claimed by the factory.

Modified Performance (Without Performance Package):

  • 669 HP @ 5500 RPM; 734 LB-FT @ 3800 RPM

Modified Performance (With Performance Package):

  • 669 HP @ 5500 RPM; 734 LB-FT @ 3800 RPM
