Air cleaner replacement.
dear all,
i'm planning to replace my 2009 FLHX stock air cleaner with Arlen Ness's 'Big Sucker' (p/n 18-510).
would anyone know whether the ECM has to be re-tuned or re-calibrated if i want to carry out this modification plan?
i appreciate your comments and insights.

American iron magazine March 2010 issue pg 56.They installed the A.N. stage 1 and said: "Since 2008 and later bikes have O2 sensors in their exhaust header pipes; the stock EFI ECM module adapts this air cleaner change. That means we and you will not have to do any EFI map changes after this install." Hope that helps.
