Data Logging 101
DiabloSport Users Only!
Download & Save, then extract the file inside to the following folder:
Documents > DataViewer > dashboards
If you have not already done so, now would be a good time to email your original backup and complete mod list over to us. Your backup and mod list should be emailed only to email@example.com
Here’s some instructions that might help you.
PREDATOR AND TRINITY USERS
You’ll need to download Diablosport DSDownloader which will allow you to upload new tunes to your handheld as well as Diablosport Dataviewer which allows you to datalog via laptop instead of just through the handheld. These can be found here:
Here’s step-by-step instructions for using the programs.
- ORIGINAL BACKUP – If this is your first time using your handheld, chances are you don’t have an original backup on the handheld yet. The easiest way to get your original backup onto your handheld, is to load the Diablosport 93 tune onto your car, which will force the handheld to save the original backup. If you’ve already saved the original backup before, then you’ll follow these steps to send it to us.
a. Open DSDownloader and connect your Predator or Trinity into your computer. The Trinity will power up on it’s own with just USB power, the Predator you’ll need to either use a wall power supply, or plug the Predator into your car’s OBD2 Port.
b. Once DSDownloader has connected to your handheld, you’ll notice 2 LARGE buttons “Send Tune to Tool” and “Get File from Tool”. You’ll select “Get File from Tool” and it will give you the option to save either the Original Backup, or Last Written Tune. You’ll select Original Backup.
c. Select a location to save your backup to.
d. E-mail your original backup to us at firstname.lastname@example.org. Now is a good time as well for you to email us your complete mod list as well so we can build your base file to start with!
- RESETTING FUEL TRIMS – Before installing the base file or any tune revision, you’ll want to reset all fuel trims. To do this, you’ll just simply disconnect the negative battery terminal for a few minutes. This will erase any stored fuel trims so that the car starts fresh each time you load a new tune file.
- STORING NEW FUEL TRIMS – Now that you’ve reset your fuel trims and installed your new tune file, we need to store new fuel trims so we can see what the car’s actually doing. It’s important that we store new fuel trims before datalogging so that all of the learning is out of the way and does not interfere with logged values. We recommend about a 30-45 minute drive around town consisting of as little steady state cruising as possible. Part throttle boost, stop and go traffic, SOME highway, are all fine, but absolutely NO WOT yet! That comes later.
- DATALOGGING – Once you’ve written the base file we’ve sent you onto the car, we’re going to have you do some normal driving. This means NO WOT. Your car spends 90% of it’s life not being in WOT, so we first concentrate on this aspect of the tune.
a. On this page, further up and to the left, you’ll see a big blue button that says “FBM DS Dashboard”. This is the dashboard we like customers to use when logging. Save the file FJP.DSH to your local folder “Documents -> Dataviewer -> Dashboards”.
b. Connect to your vehicle. Once you have the Dashboard in it’s proper location, allow your handheld to connect your vehicle in DataViewer. Once it’s connected you’ll see the “Real Time Data Mode” button light up which is a small yellow lightning bolt. Click this button so that it will load the entire list of available parameters to datalog.
c. Select the proper Dashboard. To do this, you’ll notice a Dropdown list that says something along the lines of Default, Default_DCX, or <new dashboard>. Click the Dropdown menu and select FJP. If you don’t see FJP then you have not put FJP.dsh in the proper folder.
d. Click the Connect button. It’s yellow with a “c” in the center of it. This will open live communication with the PCM and show live data. This does not mean it’s recording yet.
e. Verify that you can see live data and then click Record, the red button next to the Connect button.
f. Drive around for an additional 20-30 minutes in the same manner as before, datalogging the whole time. This will give us usable data so we can make adjustments.
- SAVING YOUR DATALOG – Once you’ve completed your drive session you can either click Stop, or just turn the car off and it will stop recording automatically. When it stops recording, it will prompt you to save the datalog. Save your datalog with Your Name and the revision number of the tune you were sent (1.00, 1.01, 1.02, etc) This will help us keep better track of what log goes with what tune revision.
- EMAIL YOUR DATALOG – After saving your datalog, please email it to us at email@example.com so that we may go over it and make adjustments.
FOR INTUNE/I2 USERS
Plug your Intune or I2 into your computer and 2 new drives will appear. “Diablosport” and “Intune”. You’ll open the “Intune” drive, and you’ll see a Tunes folder. In this folder, will be your original backup, marked with the word “backup” in the filename. Datalogging procedure is the same as Predator and Trinity units.
FOR ALL USERS THAT ARE NOT LOGGING WITH A LAPTOP AND DATAVIEWER
You’ll need to add or remove PIDs from the PID list to match what we use in the Dashboard for DataViewer. Here’s a list of the PID’s we use and the categories they’re located in. If you see a PID on your handheld that is not in this list, please remove it as it will slow down the log.
