Overview

The 2010-2016 E 63 AMG S responds well to software, and RennTech has been writing engine calibrations since electronic engine management arrived in the mid-1980s. This Intermediate ECU Upgrade rewrites ignition timing, throttle mapping, fueling and boost control on the 5.5L M157 twin-turbo V8, so the extra power arrives across the whole rev range without giving up everyday drivability. RennTech rates the E 63 AMG S at up to 638 hp and 695 lb-ft with this upgrade, a gain of 33 hp and 49 lb-ft.
