The RENNTech proprietary ECU upgrade for the Mercedes M133 engine offers huge gains in performance across the entire RPM range without sacrificing around town comfort or daily driver reliability. Unlike an ECU Upgrade, the RENNtech tuning module allows the user to change the performance level "on the fly" and gives the ability to set different performance levels running both higher or lower boost compared to OEM settings. This gives you control over the power or fuel economy with smooth torque delivery and performance throughout the entire powerband.
This also allows the you to compensate for poor fuel quality and/or locations of extreme climate (for all our overseas customers), or even to adjust for higher octane fuels for that added performance when hitting the track days. The RENNTech tuning module for the CLA & A 45 AMG is plug & play, delivered with a specific M133 engine harness to make installation easy and requires no cutting or splicing of wires. Its a beautiful thing. This does not require you to send in your ECU for upgrade, as this is module is adjsuted by the end user.
