I finished the full installation today and must say that I am quite pleased. Pulling out the stock cores was not as easy as I anticipated but we got through it. I also had a minor panic moment when I started the bike, everything was going well, and then the bike started to smoke and I had to quickly kill the ignition. After thinking through it, I figured it might be some type of lubricant or oily burnoff from the new header pipers and that is exactly what is was. Just letting the bike run 30 seconds or so cleared that up.
My friend (and HD mechanic) was very impressed with the system and thought it to definitely to be the best aftermarket solution. Also, anytime the garage doors are up and I am working on the bike, my neighbor who rides a Heritage Classic has to come by and critique my work. He was quite jealous of the sound and performance improvement as he used to bust my balls about the pathetic stock exhaust.
My only potential screw-up was with the original ecm file. I saved it as suggested and proceeded with uploading the new MT7 file. When I was finished with my work I wanted to view the original ecm file and noticed that it had a MTE file extension and the Mastertune software would not let me read it. I did not realize that you could not view this file at the time, so I changed the extension to MT7 and thought that would work until I called Steve and he informed me that the original is not viewable. My only concern is that now my computer only recognizes the original ecm file as an MT7 and will not let me convert it to an MTE. Is this an issue or if I ever had to restore the original should this still work?
