ZF ECOLITE TUNING
A new six-speed robotised manual transmission, the ZF EcoLite, was launched in 2012 by ZF for a number of brands, including Renault. Simple to use, comfortable to drive, and fuel efficient, this system is designed for light commercial vehicles.
Because of its lightweight and compact structure, it’s an excellent alternative to traditional manual transmissions, where reduced weight is crucial. This TCU can be calibrated quickly and effectively with ECM Titanium, according to the requirements of your customers.
Magneti Marelli Dualogic Tuning
In 2003, Magneti Marelli developed and designed the Dualogic robotised transmission for the FCA group’s small and medium-sized vehicles with transverse front engines. A new automatic transmission was developed that reduced production and maintenance costs without compromising reliability or driving comfort.
An electronic actuator controls the clutch and gear selection in the Dualogic transmission, which is based on a manual transmission. Through ECM Titanium, it is possible to alter the calibration of this TCU to increase gear change speed and for repair purposes. Recalibration software for ECM Titanium allows you to provide precise and reliable service to your customers.
