Hey there! I'm brand new to using HP Tuners and as following the setup video, I set up and registered my HPVI3. After setup, I noticed a check engine light and didn't think anything of it because I was in auxiliary mode. I started to read the vehicle to download the stock files and save them, but during the reading process, after the first click of reading my ECM, I ended up getting a little message on my dash where the temperature and milage are saying, "Engine pwr reduced" followed by "Engine Disabled". After the TCM was done being read, i saved my file, and then turned my car from auxiliary mode to off, opened my door so my battery was cut, and then unplugged the HPVI3. I then went to go start my car, saw there was a check engine light still there, and plugged in my FIXD to check the code and clear it, and low and behold P606 was there. I was concerned so I cleared the light, and my car started right up. Going back later to reread the vehicle after I accidentally saved over my stock file trying to follow an article on throttle response, I followed the same process again and the same code popped up after I had plugged in the HPVI3. I did already write the correct tune for the throttle response and have flashed it to that and back to stock, which is where it sits now. Is this something that I should be concerned about, or is this a normal occurrence? The only thing I can find is people getting it after a bad tune file or such. I drive a 2007 Pontiac G5.
