All I know is my bike is much smoother at idle and at cruising rpms with them and I no longer have decel popping. I'm happy, and glad the OP is happy with them.

It all comes down to what is acceptable. While the ECM can adjust for some changes, it still retains the same AFR/Lambda targets as stock and and the stock timing tables are less than desirable in most applications.

I was told this by Nightrider via. a phone conversation. Not trying to get into a pissing match, just passing along what I found in my own research on the XiEDs.

Admittedly, it is not easy to understand. Delphi doesn't really make much info available on the subject, Harley makes almost NONE available, and there is so much theory and "I think" going on that it is almost readily accepted that the Delphi EFI system can "learn" on its own. I am not a defacto expert on it but I have read tons and tons of info on the subject and nowhere at all can I find a shred of evidence that this is true.
I decided to actually learn about the efi system on our bikes, and it is a bit of a chore, but I can't take not fully understanding how my bike(s) work. I still don't get it fully, and I'm sure I'll make mistakes, and I'm sure they'll be pointed out when I make'm!

As am I happy that he, she, or whoever is happy. I'm sorry if I sound pissy with my replies, it is not my intent. I am trying to bring some facts into the typically completely without fact conversations about EFI here on this forum.

Man, things sure were simpler with carbs, lol. Change jets and throw on an open a/c & you're done. Now there's so many different programming and tuning options it's almost impossible to know if you're doing the best or right thing.

I'm no expert, all I know is they work...And the bike did run even better after I rode it all day after install. Closed loop is where most people do the majority of their riding.
Are they as good as SERT with a quality dyno tune? Absoultly not.
For 100 bucks it is the best value out there for a new harley.
I have read a lot about the delphi also but would rather be riding on it then reading about it. There is more quality info on this subject on nightrider.com then most 5 sites put together. I have talked to the owner and he will actually steer people away from his product if he feels it's not right for where they want to go with their bike.
If you have an extra 800 bucks lying around after doing the pipes and A/C then don't buy the product. For 100 bucks there is no bigger bang for your harley, period!
