RENNtech M133 ECU Upgrades are TÜV approved!
Our 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.
The RENNtech tuning module allows the user to change the performance level and gives the ability to set different performance levels running both higher or lower boost compared to delivered settings. This gives you power on demand or economy when you want with smooth torque delivery and performance throughout the entire powerband. This also allows the user to compensate for fuel quality and places of extreme climate or to adjust for higher octane fuels and the added performance of racing blends.
Our tuning module for the A 45 AMG is plug & play, delivered with a specific M133 engine harness to make installation simple and requires no cutting or splicing of wires.
