2007 Corvette Z51 A6 LS2

Hi all,

I just recieved my Intune. I followed all the instructions and it appeared to have a little glitch when I first connected it to my computer to make sure it was updated prior to tuning my Corvette.

Initially I got an error that the usb drivers could not be installed, I waited a little bit and then the Intune updater appearred on my computer and it begin to download updates. I just left it alone and let it do its thing. It finally rebooted and all seemed well but I was concerned about the USB error I had recieved earlier in the initial connection. So I disconnected the USB port and reconnected. Again I got errors that USB drivers had failed to install, but also the intune updater screen appeared and it stated that the device was up to date.

I searched here on the forums and read a couple of posts about running Intune.exe as an administrator. It was at this point that I made a discovery. I was browsing My Computer and noticed that Intune installs itself as a CD drive and another drive as a USB drive. Initially I could not find the intune.exe file and finally realized that I was looking on the "USB" portion of the unit as opposed to the "CD Drive" portion of the unit. Eventually I found the intune.exe file on the CD Drive portion and right clicked and ran it as an administrator. All appears to be well in that department now.

I really think that the instructions could be a little more clear on this portion of the install.

I then decided to go ahead and hook it up to my OBD port in the car. I had read some posts about some TCM's not being recognized. I was pleasantly suprised to see that not only was my ECU recognized and that I had three options available. Modify Stock, 91 Octane, and Diablosport Tune. I chose the 91 Octane tune as I only have available 92 ethanol free fuel available here at this time. Intune then prompted me to select a TCM tune. It gave me the choice to install a firm tune, a hard tune, or modify stock if I recall correctly. At this point I selected the firm tune. I followed the rest of the prompts and allowed it to write the ECU and TCM.

Here are my current concerns and observations.

1. I would like to do some datalogging and learn a little more about what the car is doing on the stock tune first so I will likely return it to stock tomorrow and just monitor the default PID's

It was late tonight and with the BB exhaust my wife was pissed that I even started the car with the daughter asleep. (Had to do it just to do a short log)
what should I look for and be concerned about.

2. Which PID's are most important and where can I learn more about tuning.

3. I noticed when pushing some of the prompts with my fat fingers it didn't always want to recognize that I had pressed a icon. I see that under Settings...Advanced there is a touchscren calibration. Should I use this to see if it helps. Should I return the car to stock prior to doing this. I'm assuming I have to write down the code sequence and then enter the sequence on the following screen.

4. What can I expect to be different between the Firm and Hard TCM tunes.

Anyway, so far I'm impressed with the device and looking forward to driving the car tomorrow.

Any suggestions and advice would be appreciated.
