| enabled | Integer, 0 or 1 | 0=disabled 1=enabled |
| minclt | Integer | Defines the minimum coolant temperature the engine must be at before any autotune averaging is performed, if autotune is enabled. |
| defaultstate | string, off or on | Defines whether the default state of autotune is off or on if it is enabled. So for example, if defaultstate=on and enabled=1 then as soon as minclt is reached, autotune averaging will start. If defaultstate=off, then autotune averaging will not start unless it is deliberately turned on using a touch or button action. |
| minvisits | Integer | The number of times a cell must be visited before a VE calculation will be performed. This is a sensitivity setting to ensure that new VE values are not calculated on insufficient data |
| dfcowaittime | Integer | Number of milliseconds after a Decel Fuel Cut event to wait before resuming autotuning (default 2000). |
| accelenrichwaittime | Integer | Number of milliseconds after an accel enrichment event to wait before resuming autotuning (default 2000). |
| dfcotype | String | Valid values are statusbits or pulsewidth. The statusbits setting, which is the default if not specified, is used for Speeduino ECUs to determine whether the ECU is in Decel Fuel Cut mode. If this setting is changed to pulsewidth, then the autotune module tests the injector pulswidth for zero to determine when the ECU is in Decel Fuel Cut mode. |
| pulsewidthattribute | String | The name of the attribute to be used to get the pulsewidth from, when the dfcotype is set to pulsewidth. The default value for this setting is pw1 if it is not present in the ini file. pw1 is the pulsewidth for the primary injectors in Speeduino. If you are using a different ECU, this setting will need to be correct. Note that if your ECU does not provide a pulsewidth either, then you could use something else as a proxy for it, such as Injector Duty Cycle. Whatever you use has to be zero when decel fuel cut is active. If the attribute selected in this setting can’t be found during boot, then the autotune feature will not work. |
