Doubt that it has anything to do with the problem. Normally the temp differences between locations is minimal and will have no effect when going down the road. Temp differences show up only on a shutdown and sitting for 10 minutes or so, where heat soak can occur. Then some running differences can be felt, mostly at idle or jerky at 3k if the tune is lean in that area to start with. The IAT has some fuel control but nowhere to what you are experiencing. Hell, I can unplug mine and go around the block and it will run the same. Wasn't intentional but forgot to plug it in once. It effects both cyls at the same time, not just one, so suspect it might be Tmax related. I've not used Tmax on the v rod but on a softail once. It can be quirky.Ron I was hoping you could help me out here. After changing that IAT sensor location my bike is running horribly. After moving it, I ran the IAC Auto-Calibrate and AutoTune through my ThunderMax. The IAC auto-calibrate I ran last night before going to bed. It had the rear cylinder running rich. So I figured the AutoTune would clear it up and planned on going for a long ride in the morning. Rode it this morning and it's acting like I've got a bad spark plug. Hesitations. No codes. So after a 45 minute ride I brought it home and ran the IAC again. This time rear cylinder was lean. Ran Autotune. I just got back from running through nearly two full tanks of fuel and it's still running horribly. It ran aces before I switched the location of that IAT sensor from the battery area to the airbox lid.
