In case anyone else wonders what this does, Google Translate for the description:

K2, the enhanced version, speeds up attributes such as drones, mining machines, and power generation. Easier to get started. Copyright remains with the original author.

It's based on K2 version 1.2.25 (2022-03-12). There are just three files that are actually different between K2 1.2.25 and K2 Plus 2.2.0 (aside from changing K2 to K2Plus and bundling K2 assets). All of them are in vanilla-changes/mandatory, and they are equipments-changes.lua, vanilla-robots-changes.lua and vanilla-energy-changes.lua. All the changes are essentially just cheat level changes.

Examples:

data.raw["solar-panel"]["solar-panel"].production = "6000kW" -- Changed from 100 kW
data.raw["character"]["character"].inventory_size = 120     --背包
data.raw["character"]["character"].max_health = 90000       -- 生命值
data.raw["character"]["character"].build_distance = 100     --建造距离
data.raw["generator-equipment"]["fusion-reactor-equipment"].power = "320MW" -- Changed from 3.2 MW
data.raw["solar-panel-equipment"]["solar-panel-equipment"].power = "1200000kW" -- Changed from 40kW

There are more changes, but you get the gist of it.
