Diablo Intune Information Part I - The Intune size comparison I hear comparisons of the Diablo Intune to a credit card which I can understand, but don't believe to be really accurate so I decided to post some comparison pictures with a smart phone like the Iphone 4S to get a better comparison about its size. Part of this is because when I went to Diablo's web site and looked up the intune my first impression was that the Intune was some sort of app you could install on a smart phone (which in my opinion it should be). It just makes more sense to use better hardware like an Iphone or a Galaxy S3 where you have a higher quality touch screen display and massive storage. But then I found out it was the Intune was actually a piece of hardware like any other programmer. Anyway for people that are looking at getting an Intune, I love mine after having it 3 months and this is what you are getting when buying an Intune (Iphone Not Included :gasp: The Intune does not have a battery or run on its own power. The Intune gets its power from the USB cable when it is connected to a computer or the OBDII cable when it is connected to your vehicle. Part II - In the vehicle The OBDII port under the dash on the drivers side of the truck. The OBDII cable that came with the Intune connected to the OBDII port on the truck. The Intune connected to the truck and then connected to the netbook running Diablo Data Viewer 18.104.22.168 for live data logging (Part of the reason I did not go with a Trinity) Part III - Software for the PC The software is pretty good and depending on the size of your laptop, it will be easier to read than the screen of the Intune. The Intune does not have a fancy display like the Trinity, but that is what the computer is for . If you have a local drag strip or track where you can rent time, then you can push the truck and record data for your Wide Open Throttle (WOT) data log. Part IV - Other Information. If your software updates are current as of this article (GM Specific): Trucks from 1999-2013 are supported. Gas and Diesel are supported. Adjustment of transmission shift points are supported. Newer trucks with fancier computers than mine will probably have more options that can be logged. Additional Information: When you buy one, the first thing you want to do is connect it to a computer with an internet connection and let it self update before using it the first time. This can take up to an hour depending on how many updates there are. Part V - First time use When you connect it to the truck the first time, the Intune automatically backs up your factory settings and writes them to a file. Next you have the option to pick from (typically) 3 custom tunes from Diablo. Once you pick the tune you want, you can choose to load it into the computer on the truck. You load the tune, following the on screen instructions and the tune is loaded. Now you can disconnect the Intune and no longer need to leave it connected to the truck. The re-tune of the truck is complete.
