Seriously no offense taken. I just wanted to ensure that I was on the right track. I read in some other thread to go ahead and have the bike at operating temp before swapping ECM's then performing the TPS reset so that enrichment isn't on. Are there any other gotcha's that I should be aware of? Thanks for that info and really I wouldn't be offended by speaking the truth. Now, I know how to tune a more modern Harley no problem but these guys here are a different story.
