2024年6月15日 · A gasoline AFR of 20:1 is considered lean, with a high air content and low fuel content in the exhaust. Finding the optimal AFR is essential for balancing performance and fuel economy. For pure gasoline, the ideal stoichiometric ratio is 14.7:1. This ratio provides the best compromise between performance, fuel economy, and emissions.

There are three labels here for each line chart (color coded by parameter). The top value corresponds to the top edge of the chart. The middle value corresponds to the horizontal line through the center. The bottom value corresponds to the bottom edge. 4. Time Index. During playback of a log file, this vertical bar indicates the current time index.

Load one of the pre-defined chart vs. time layouts. Add a new (empty) chart group. To complete group setup, add the signals (series) that would be included in the group. Delete the chart group selected in the left column. Add a new signal (series) to …

NTK Calibration grade sensor highly recommended for low AFR methanol applications. NTK Production Grade is the least expensive sensor we recommend for methanol applications. The base AFR500v3 includes the following: Large, bright digital display controller (~3.4in x 2.7in x 1.3in). 13ft wiring harness with sealed connections.

The X-Series Wideband AFR OBDII Gauge includes an OBDII pass-through connector and Bosch 4.9LSU sensor that can be free-air calibrated or used with the factory resistor calibration. Additional wiring for a 0-5v or RS232 Serial output can be added by the user for outputting to …

Math Parameters. Math Parameters Manager can be used to create complex values that take into account multiple channels.

NTK Calibration grade sensor highly recommended for low AFR methanol applications. NTK Production Grade is the least expensive sensor we recommend for methanol applications. Summary of specific changes to the AFR500v3CAN: Programmable CAN termination resistor. Sensor Averaging Filter setting. O2% output. Fault condition diagnostics.

Show only the data gathered during the time frame displayed in the Chart vs. Time panel. 3. Percentage of Distribution. Each bar represents the percentage of time that the graphed parameter was observed with the indicated value.

3. Double-click on the parameter whose values will be mapped in the cells of the new table. A blank table should now appear on the Graph panel.

The spark system still has to calculate the main spark with all its offsets and modifiers. Likewise, the fuel system still needs to calculate the commanded AFR, the injector pulse width, what fuel mode it's in and then somewhere in the process it sees that the torque system wants to cut 2 cylinders, so it does that as well. The Electronic ...
