    I want to change the "football" air cleaner cover to a round one. I am wondering if I will need to change the fuel map if I do that. Here is what is on the bike now:

    2005 FLSTCI
    Screamin' Eagle air cleaner with football cover. The filter is round.
    V&H Long Shot exhaust; no baffles.
    Factory EFI.

    I'm not 100% certain but my guess would be that the cover makes no difference unless it significantly alters the amount of air getting in.

    I am in about the same situation as you, meaning that:

    I've changed my exhaust (V&H shortshots)
    I've got a high flow air filter (SE - with football cover)

    and I want to get a smaller filter cover since I like that open element look.

    Now the only thing I've got different than you is that I've got my EFI remapped to accomodate the high flow filter and the new pipes, so I think I can get away with it without a remap..
    You on the other hand have changed both intake and exhaust without a remap, so it's my guess that you are running pretty lean by now.

    So long story short, I'd get my EFI remapped, not due to the cover, but due to everything else you've changed.

    Take care,

    That cover is wide open in the back dont think it could let in any more air even if u took it all the way off it real just keeps the air cleaner a little cleaner and keeps the rain off it... but with the open element a good rain will do u in if u dont got a rain sock with u.
    I have found that out first hand

    I guess I didn't provide enough information. I bought the bike the way it is from a dealer. It seems to run good at idle (haven't had it on the road yet as I got it in December). I am guessing that whoever installed the a/c and exhaust had the remap done or did it themselves. Is there a way to tell if the factory EFI has been changed from stock?

    I did some research to verify this new information and it only creates more questions. I understand the Harley fuel map on the '05 is not adjustable. Did I understand that corectly? If so, then how does the engine stay running well when the air and exhaust is opened up? From other help files I understand that changing intake and exhaust only will result in a lean condition.

    Thank you for the education.

    I have a related question, I had SE Air, Vance & Hines short shot staggared, and a PCV installed when I purchased my FLSTFB, If I changed the SE Air to a K&N Air Charger should I remap.

    Thank you again smitty. If the bike runs great, and I'm sure it will, I'll leave it alone (if it ain't broke, don't fix it). However, if my cousin gets the stage 2 done on his '85 Superglide, I just may hafta..... :newsmile020:
