Autotuner — ECU Remapping Hardware for Professional Agents
A fast, intelligent, and versatile ECU tuning tool trusted by professional remapping agents worldwide. Available as hardware only, slave activation, or master activation — with free online training, 5-year warranty, and live 5-day support.
What is the Autotuner?
The Autotuner is a professional-grade ECU remapping and chip-tuning tool designed for both OBD diagnostic port access and direct boot mode reading. It reads and writes original and tuning data from the vehicle's ECU quickly and reliably, with the file encryption and decryption process handled entirely by the tool itself.
Powered by a Cortex M4 processor, the Autotuner is exceptionally fast — significantly reducing read and write times compared to older hardware. It automatically performs a backup of TriCore information online, giving you an additional layer of protection on every job.
MVRH ECU Tuning Solutions is your master tuner and ECU file service provider. When you operate as a slave agent under MVRH, you handle the physical read and write at the vehicle using your Autotuner Slave, and MVRH supplies the calibrated tune file. VIEZU is a separate company and one of the UK's largest tool resellers — they supply the hardware, while MVRH provides your ongoing file service and master support.
