Some day you may find yourself in need of taking a data log with your Sniper EFI system.
It's going to be simple to review data on your own or to email a file to somebody else
for review.
There are two ways that you can take a dat log and I'm going to discuss both options
with you today.
One method is to use the 3.5 inch LCD touch screen and you can data log directly to the
SD card.
The other method we're going to discuss is using the PC based Sniper EFI software and
data logging directly to your lap top.
One of the things that you will need if your data logging with the 3.5 inch LCD touch screen
is going to be an SD card reader in order to get that data out of it.
If your PC does not have a built in SD card reader, you can get a USB based add on SD
card reader at a reasonable price.
If you're going to data log directly to the PC, you will need to get the part number 558-443
USB that will plug in to your cam connection in place of your 3.5 inch LCD.
Let's go take a look at our Camaro and we'll show you how to get these data logs taken
care of.
To take your data log using a 3.5 inch LCD touch screen, you simply need to go to the
home page, select logging, and to start the data log simply select start log.
Once you've recorded the data that you want to log, you can simply select stop log to
end the logging function.
One thing to make note of if you select files, you will not be able to view the actual data
log files that are stored on the SD card.
However if you want to delete that data log or delete all of the logs that are stored
on the SD card, you can do so by selecting delete log, or erase all.
From this point you'd want to shut your ignition off, and remove the SD card from the 3.5 inch
LCD touch screen.
We'll then go insert that into our SD card reader and we'll show you how to mange those
files.
Once you've completed taking your data log with your 3.5 inch LCD touch screen, you've
removed the SD card, in order to access those files, you simply need to insert the SD card
through a suitable SD card reader, and then browse to the SD card on your lap top.
When you open the SD card you're going to see a folder labeled save data logs.
You can then copy and paste the log into an email or you can save it through a different
location of your choice to be accessed later.
To take a PC based data log, you'll need the USB dongle part number 558-443.
This will connect in place of your 3.5 inch LCD touch screen.
Care should be taken when disconnecting the 3.5 inch LCD, make sure that you completely
depress the release and pull on the connectors.
Be careful not to pull on the harness as you could damage it.
Once you've got it connected and you connect into the back of your PC, your communication
status at the top will change from off line to USB link.
With ignition in the run position, you can select USB link to sync with your ECU.
This screen will close out in about 5 seconds.
Once it says that your online, you can now take a data log.
To start a data log with the PC based software you would click on the clipboard, to start
the log and you'll notice the color changed from brown to red.
Once you've completed taking the data log, you can click on the clipboard a second time,
that will stop the logging process and allow you to label the log.
The default log will be by date as well as time and you also have the ability to re-label
it as you see fit and simply select save.
We've completed taking our data log directly to the laptop using our Sniper EFI software
and our 558-443 USB dongle.
Let's take a look at how to access these files and how to bring them up where we can view
them in the data log viewer.
Once you have completed taking the data log with the Sniper EFI software, or you have
downloaded a saved dat log from the SD card that you had previously removed from your
3.5 inch LCD touch screen, you can open a data log viewer by clicking on data log, and
then open data log.
You can then browse to the location that you have saved the .dl or data log file to and
open it by simply double clicking the file.
Congratulations on successfully taking and opening up a dat log in your data log viewer.
