Logging¶
Any troubleshooting begins with logs. One of rusEFI powers is the amount of data points available for logging!
Shaky videos will not do. Even high-resolution screen shots wil not do—it has to be a proper log file.
See the Logging Guide.

FAQ¶
Q: How do I change settings?
A: You can change settings and your engine tune using TunerStudio.
Q: Do I need to compile source code myself?
A: Nope, not at all. Prebuilt bundles are available on the Download Page.
Q: I've made some changes in TunerStudio & hit Burn. 'Need Burn' has appeared but the values are not there after rusEFI reset?
A: rusEFI does not write to internal flash memory while your engine is running. In order to really write the values into the permanent memory you would need to stop the engine (or disconnect your stimulator). Online tuning is not affected by this issue; you can tune and the new values will be applied right away, but they will not be saved until you stop the engine.
Q: I've remapped some analog inputs and outputs but nothing has changed, looks like the old pins are still used for output?
A: For most of the pinout changes to be applied you need to reset rusEFI. Do not forget to stop the engine so that the new config is saved into internal memory!
Q: What does this error code mean?
A: See Error Codes
