How to setup a histogram for a Bully Dog Tuner?
1. The first and most critical step is selecting the correct PIDs for the histogram you would like to create. You need to know what PIDs will correspond to the to the table you are looking to create a histogram for. In this example, we are doing a Load with Failed MAF Table as pictured.
The X-axis is RPM, the Y-Axis is Throttle Position Relative in counts, and the Z-Data is Load for the table above. During our PID selection screen we are going to grab these PIDs. You may select additional PIDS, but you must select these PIDS so that these channels can be utilized in our histogram.
Once you have selected the PIDs, you can configure the data log and begin creating the histogram. In the top menu bar click Add in the Histograms area. When the Histogram box pops up, click Add New.
A new tab at the bottom left of your screen will appear and you will be on the Histogram Settings tab. When we save this histogram later, it will change from “new” to the name you save it as.
Now it's time to start configuring our settings of the histogram. Follow the instructions on this image.
Now on the LEFT side of the page, click on Histogram and check if your table matches the table in Advantage. It should be the same size/dimensions as the original table, in this case the Load with Failed MAF table.
Switch back to SETTINGS using the left side tab, and click SAVE As… at the bottom right corner to Save your histogram for later use.
A histogram can be created before logging, or even after logging if you have already data logged the correct pids for your histogram. You can also grab the small tab at the bottom left and drag it up, to create a floating histogram window on your chart view.
You can filter your histogram to display different ways using the buttons on the right of the Histogram.
VAL = Value = Displays only the current value for the spot you are at in time line.
CNT = COUNT = Displays how many time each cell was “hit” to collect data. This is helpful to filter out cells that were not hit frequently to collect reliable data.
AVG = AVERAGE = Displays the average value for each cell up to that point on the timeline. This is the most commonly used button.
MIN = MINIMUM = Displays the lowest value for each cell that data was collected up to that point in the timeline.
MAX = MAXIMUM = Displays the highest value for each cell that data was collected up to that point in the timeline.
