PART 2 – V7.5 SCANDATA LOGGING
This is the console screen.This does nothing more than keep a chronological record of everything that goes on.Any errors, issues, connection problems, etc., will be logged here and, if needed, can besent to your tuner or EFILive to try and resolve the problem.
This is the OBDII screen.Anything related to modules, codes, system readiness tests, etc., is accessed on this screen.The tab that is currently selected is DTC (trouble codes).If you look directly above the PID tab, you will see what looks like small engines. The far left one isnormally solid red. You press that to bring up any trouble codes. The third one to the right isnormally solid green. That one clears any current trouble codes.
This is the screen that most users find difficult at first. This is where you select the parameters thatyou want to monitor. Prior to creating any gauges, charts, etc., you need to create and save your PIDlist, which you do here.For most users, the pre-defined groups that I have selected to the left will fit most needs.Remember, you can only monitor 96 PID’s and theyare grouped, you can’t select individual PID’s likeyou can with a GM vehicle.The PID’s to the left are in the groups selectedabove.
Once we’ve selected our PID’s and saved our PID list, thenext tab over is the Data tab.This is the raw information as it’s happening.As you can see, there is a lot going on and it’s simply toomuch to absorb and much of it isn’t critical or even whatyou are really looking for, but because we are forced touse the pre-determined PID groups (Cummins not EFILive’sdoing), that information is there.So, what we need to do is take the PID’s we want and putit into a format we can use. That takes us to the next tab.
This is the Dashboard.This is likely the tab you’ll use the most. This is where you create your charts, gauges, andotherwise filter down the PID’s that you need and put them into a visual format that you canmore easily use.The information that you see displayed is a chart, actually it’s 3 charts. Each chart can display4 PID’s, which we’ll get into later.The dashboard can also be setup with analog gauges, digital gauges, and several other formsof visual displays that meet the users needs.You can scale and color each as you need or see fit.Up above you see the letters A,B,C. Those are you DASH PAGES. They form your DASH BOARD.
This is the Maps tab.For the new or casual user, you may not ever use this tab, but if don’t you’re missing out onan incredible tuning tool.This allows you to create custom maps that, much like the maps you see in the Tune tool,have data with 2 axis’. The difference is, you select the data displayed AND you select the 2axis’ that you want it referenced against.It sounds more difficult than it is, but I’ll show you how to do this later.
This is the Dynamic Vehicle Testing Tab.This is not currently used or supported on the Cummins, it’s a GM tool, so we’re not going tospend a lot of time on this.
Let’s get started!You’ve probably already used your V2 and the Tune tool so we’re going to go into getting yousetup to data log.Where people make the mistake is NOT using this. If you’re not using this incredibly powerfultool, you’re tuning in the blind.What you need to do to get started the FIRST TIME you do this is have the V2 connected tothe vehicle and your computer. With the key in the run position, click the GREEN Connectbutton. This will bring up a window that asks you to select your controller. You either want toselect the Cummins controller for either the 5.9 or 6.7 and check the box for automatictransmission, if it applies.The program will then connect and you’ll see the GREEN button turn off and the RED buttonturn on.
Now that we’re connected, we can select our PID’s. You only need to have it connected to thetruck the first time. Once you select and save your PID list, you can open it any time.What you can see we’ve done here is selected our Pre-defined groups that give us the“Best Bang For The Buck”. Select the groups that give YOU the most usable parameters.The ones selected here are the ones I use, but many not suit your needs.Once you have your PID’s selected, SAVE your PIDlist by going to the File drop down menu at thetop.
Now that we have our PID’s selected and saved, we’reready to actually see some data.At this point we could see the raw data if we wanted to. Allyou have to do at this point is go down to the bottom of thescreen where those YELLOW and RED buttons are.The YELLOW button is to MONITOR parameters and the REDbutton is to start RECORDING them.Either way, when you chose to stop, you’ll be given theoption to save the data log.
BUT, like I mentioned earlier, the raw data is WAY too hard to follow along with and make anysense of with in any reasonable time.So, what we need to do is take all that RAW DATA and weed out the information that wereally don’t need and put the data that we DO need into a usable, visual format like the set ofcharts that I have here in the background.This set of charts and it’s parameters are the same ones I normally use with my own vehicle.On the left side, from top to bottom, you have: RPM, Boost Pressure, Commanded Fuel(mm3), Main Timing, Gear (transmission) and TOS (transmission output shaft speed).On the right, again from top to bottom, you have: Coolant Temp, Engine Load, Main Duration,Pilot Duration, Commanded Governor Pressure and Actual Governor Pressure.
No, let’s create one of these charts.First, we need to clear the page. On the same row as the A,B,C, all the way to the left there is an icon that looks like a blankpage, push that. Now, right click on the main page area, select Remove background image. Now we’re ready.To add a chart or gauge, look at the pop-ups below. Right click the main page area, select Add – Chart – New chart.
This will give us what we have here.This is too small to work with and demonstrate, so I’m going to resize it (just like anything else windows based) so you cansee it.
Now that it’s resized, we see that the chart has no information.We have to tell it what parameters from out PID list we want it to display.To do this, right-click the chart and select Chart properties. A new box will pop up.
This is our chart properties.Here is where we tell thechart what PID’s from our listwe want displayed on thischart and how we want themformated.In the selection to the right,I’ve chosen Engine RPM’s formy first parameter, and I wantit in YELLOW with a range of 0– 5000 RPM’s.Once you do all 4, you saveyour chart and call itwhatever you like.
Here’s our finished chart.We selected RPM’s, Boost PSI, Commanded Fuel (mm3’s) and Rail Pressure.You can resize this to fit it how you want and you’re really only limited by the amount of screenreal estate that you have.
Here is our data in visual format
Now that we’ve used most of the basic functions, lets look at one that not everyone uses the Custom Maps.When used correctly, this is one of THE most powerful tools you have to tune your truck.The reason this is so powerful is YOU determine WHAT you want to see and HOW you want to see it.You select everything from the main data displayed to the parameters used to display it.BUT, it’s not as hard as it seems to set up. It’s actually quite easy.If you already have maps created, you just press SHIFT CTRL M to load a map.If you want to create a new map, you press CTRL ENTER.
When you press CTRL ENTER, this iswhat you’ll see.Much like the charts, you pick theparameter and you name it. This isfor the data INSIDE the map. For ourmap, lets say it’s Main Duration.You then do the same for theColumn, the Rows, select cell colorsand decide if you want cells with nodata empty and what determines anempty cell.
Now we have our map created.The data that will be displayed inside of this map will be the Main Injection Duration.The parameters that it will cross it with is Commanded Fuel (mm3’s) in the Columns and Engine RPM’s in the Rows.What this allows me to do is determine just how many microseconds of duration my tune is producing at a givenRPM when I’m asking for a given amount of fuel.What you’ll see in the next page is that a good majority of your maps are COMLETELY unused.
What you see here is the average number of microseconds (uS) that this tune produced over a in the given cellsover a 12 mile route from our shop to a store.This was just normal driving, nothing aggressive, just as I would on any given day.As you can see, very little of the map is being used. What this does is allows YOU to focus your efforts on the partsof your tune that actually get used and not waste time on things that are generally irrelevant.
