Speed Up Your ME Import and Export Buses

Understand Bus Upgrade Slots

Import Buses, Export Buses, and I/O Ports all support upgrade cards that accelerate item transfer rates. These upgrades help move materials faster between your ME Network and connected machines or inventories.

Install Transfer Speed Upgrades

1. Craft the appropriate upgrade card for your bus type

2. Open the bus interface

3. Place the upgrade card into the designated upgrade slot

4. The bus will immediately begin transferring items at the new speed

Optimize Your Network Flow

If you're bottlenecked by slow item movement, prioritize upgrading buses on high-traffic routes—those handling multiple stacks per second. Combine bus upgrades with Parallel Cards on connected machines for maximum throughput.

Stacking Effects

Upgrade cards work independently; installing one card doesn't prevent you from using others. Plan your upgrade distribution based on which parts of your factory need the most help.
