especially since I just had my car in for service but I know that I made sure to restore the stock tune to the vehicle before they ever saw it. Turns out that the message that says to unplug it when it’s in the “main screen” or “disclaimer screen” when you do the I2 updates is misleading (to me it was) because it’s already in the main screen when this message is displayed, and stays there for a good while afterward making you think it's done.
Leave the tuner sit there for a good 10 minutes maybe longer or so plugged in to your PC after the updates are “done”, and you will see a message that says “preparing” this will last 5-10 minutes and then it will start “writing”, then it will go to "preparing" for another 5-10 minutes, then "writing" again. After the second time “writing” it said “verifying”. Then it went into the main screen and instantly rebooted. After reboot, it said “Installing” then “upgrade complete” that only took a few minutes. I then unplugged it from my PC.
Next I plugged it into my vehicle. It now gave me the message “A PCM calibration update has been loaded for this vehicle. It will now be prepared for installation" after I selected "Write Vehicle". Then you have to press “Continue”
Then it writes the “Calibration Update” to your vehicle - similar to how you tune it with turning the key off and on etc...
After that I was able to tune 13’ my Chrysler 200 V6 with no issues - back in business.
I have had this thing a year and have never seen it do updates in this way. Maybe because it’s a major upgrade instead of just an update? I honestly don’t know.
This may not be your problem but it was mine and I hope this helps someone.
