The TE and TXC 2010 have the same part number for the ECU, so they should be identical in behavior. The TXC PC5 unit will work for the TE, get the AutoTune module- well worth it.
Hey now, I am one TXC owner who has said that there was not something right from the start. My bike acted exactly like the first Dirt Bike test. If you re-read that article you will see there bike had the same issue. I do think some bikes are worse than others with this but I also think there is a fix in the works. I too am glad Kleeman got his bike out to Dynojet.
I have sold a few PCV & AT for the 2010 TE250. All PCV's models for the Husky's are physically the same. The part number changes based on what map is preloaded from Dynojet. I have suggested download load the map posted for the TXC or using AT starting from a all zero base map.
