Mercedes Benz CLA45 AMG
High performance vehicles from AMG are known to be tuned conservatively from factory while still making strong power to generates customer sales. The 45AMG powerplant is no exception, with great results seen after tuning the ECU.
The car tested for the purpose of ECU tune dyno testing was a US-Spec 2014 CLA45 AMG running CA91 premium pump gasoline with no modifications. From running the car on a AWD Mainline Dyno the first thing to note is the way the torque-split transfers power between the front and rear wheels. From tuning the ECU alone gains of +68wHp @4550rpm (+43wHp peak Hp Gains) and +102wTq @3500rpm (+30-35% extra Torque) were seen to the wheels on the dyno. Dyno results are displayed below (Blue – Stock, Red – Tuned) . Drivability testing proved that getting grip on the stock Continental tires is now a problem.
The CLA45 AMG is supported by OBD2 flashing.

The CLA45 AMG redefines the compact car sector. Boasting the highest horsepower:liter ratio of any production vehicle, the 2.0L Turbocharged powerplant puts out a whopping 355Hp@6000rpm! Power is put to the tire via a multi-disc clutch with AMG-specific electro-hydraulic control, that makes variable torque distribution possible. Depending on the handling situation, torque distribution can vary from 50:50 AWD 4-Matic (Front:Rear:) to 100% front-wheel drive. This all makes for an exhilarating driving experience.
