Ditch the Flap.
Fix Your Airflow.

MAFSync is a custom hardware bridge that lets you drop your restrictive, mechanical Vane Air Flow (AFM) meter and run a reliable, hot-wire MAF sensor. Get back your smooth idle and crisp throttle response without the headache of wiring a standalone ECU.

FAQ - MAFSync

What It Is & How It Works

The Hardware Bridge

Those original barn-door AFMs are mechanical bottlenecks. Worn carbon tracks cause dead spots, and the heavy spring flap dulls response.

MAFSync sits between a new, reliable mass air flow sensor and your factory harness. It takes the clean MAF reading, applies a highly characterized curve, and outputs the exact analog voltage your factory ECU expects to see.

Under the Hood

Built to survive the heat and vibration of the engine bay. We replaced decades-old mechanical failure points with solid-state reliability.

Supported Platforms

European Classics

If it runs a Bosch Motronic or L-Jetronic system with a flapper door, we are likely building a profile for it. We have active development across multiple German platforms to smooth out erratic idles and rich running conditions.

JDM Legends

Denso and JECS vane airflow meters suffer from the same mechanical wear and restriction as the European units. MAFSync translates these signals to wake up classic Japanese powerplants.
