Description

RENNtech’s intermediate level ECU upgrade for the Mercedes M278 engine still offers huge gains in performance across the entire RPM range, but with a slightly reduced peak HP and torque from their standard tune.

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.

RENNtech’s intermediate ECU tune increases performance from 402 HP and 443 lb/ft torque to 480 HP and 523 lb/ft at the crank! This is a slight reduction from their standard tune but still offers white knuckle performance at one of the most affordable price points in the tuning market.

  • Note: They have found the new M278 engine stock performance numbers vary from the baseline figures claimed by Mercedes Benz. They typically see slightly higher baseline numbers than claimed by the factory.

E 550 (C207) Stock Performance:

  • 402 HP @ 5,000-5,750 RPM; 443 LB-FT @ 1,800-4,750 rpm
  • Note: Mercedes M278 engine performance when measured obtains higher numbers that rated from factory.

 

Modified Performance:

  •  480 HP @ 4900 RPM; 523 LB-FT @ 4100 RPM

 

*NOTE – We would need either the ECU or the vehicle bringing to our premises in Cheshire
