For these, programming requires either a bootloader exploit (rare) or replacing the entire MCU with a pre-flashed chip. The community is moving toward open-source hardware—like the Lishui-compatible "OpenESC" project—that mimics the pinout but runs VESC firmware.
However, respect the hardware. The engineers at Lishui set limits for a reason: thermal dissipation, MOSFET safe operating area (SOA), and battery C-rating. Incremental changes (10–20% over stock) are usually safe. Doubling currents is a recipe for smoke. lishui controller programming
