I'm new to this forum so excuse me if this has been discussed before.
So before I did anything I connected the i2 to my computer and updated it with the latest download. Everything seemed to go smoothly. Then I hooked it up to my truck and selected the 87 Octane option under Easy Tune. I also selected change Tire Size to account for my 32.8" tires. Everything seem to go as described; lights flashing, dampers flopping, I turned the key off and on a couple of times. Then I drove the truck around town for a few days before I took it out on an open road to check the speedo. It clearly had not taken the Tire Size input; the speedo was still about 8% off. I then hooked it back up to the truck to check the Axle Ratio. Again going through the Easy Tune menu, I selected change Axle Ratio. The display showed 55050_ and wouldn't allow me to input any numbers. There were up/down arrows, but they only allowed whole number changes only after many presses. So, I aborted that install. While I appreciate the potential increased HP and fuel economy, correcting the speedo was also an important reason for purchasing the i2. Please advise!
PS, a detailed users manual would make your product significantly more useful.
