While many mapping tools lock users into predefined tile providers, the Med91 Multimap allows integration with custom tile servers. If your organization hosts proprietary geospatial data (e.g., internal facility blueprints, restricted terrain models), you can stream those tiles directly into the Med91 interface without compromising security. Unlike modern MED17 ECUs, the older MED9

For enthusiasts of the VAG (Volkswagen Audi Group) platform, the Engine Control Unit (ECU) is a legendary piece of hardware. Found in the 2.0 TFSI engines of the Golf GTI Mk5, Audi S3 (8P), and SEAT Leon Cupra, it is the brain behind some of the most tunable cars on the road.
