Frequently asked
What can I tune on the CFMoto 300NK-300SR 2020-2023?
This verified definition exposes 20 calibration tables — including fuel, ignition, throttle, air & exhaust and idle maps — plus 2 adjustable scalars and 1 feature patches, all editable in your browser.
Do I need to remove or open the ECU?
No. MotoEditor edits the calibration and exports a standard BIN. Reading the stock file from the bike and writing it back is done with your own flashing hardware and software.
Which ECU does this CFMoto 300NK-300SR definition cover?
The Bosch MSE6.0 (Bosch). Every map address and scaling is verified against the stock firmware, so what you edit matches the real calibration.
Can I use my own stock file?
Yes. Start a project from your bike's stock BIN and your changes apply to it, or begin from the built-in reference — either way you export a standard BIN.
How much does access cost?
MotoEditor is a single subscription that unlocks the browser editor for this definition and every other bike in the library — no per-project or per-download fees.
