I was told at the Harley Shop that I would not have to recalibrate the ECM if I only installed the SE Stage 1 Air Filter kit. After buying it, I was suprised to read in the instructions that Failure to properly recalibrate the ECM can result in severe engine damage. Who should I believe?

 

What's your combo?

 

Well, opinions vary ... having said that, general rule is, if you change A/C AND pipes, you need to remap. If you just change one of them you don't.

 

My bike is 08 Ultra Classic and the only change is the SE Air Filter

 

The bikes run lean from factory..increase the air going in or out makes bike leaner.
Read spark plugs for non-specific idea of lean..
I would consider something to add more fuel to bike.
Many options and prices.

 

I think the MOCO recommends a flash with intake. Much more air coming in....

 

That's what I did with my '04 RK, and it still ran borderline lean. A PC V w/canned map from Fuel moto solved that - no more spitting back through the intake off-idle. The engine runs cooler and stronger, and even sounds better. Maybe the closed loop EFI on the newer bikes will compensate for the AC without a flash?

 

The dealer told me to flash the exhaust upgrade but that the intake doesn't require a flash. That's what I did and haven't had any issues over the past couple years.

 

I had the SE air filter installed and was told I needed the remapp. Once I remapped I installed SE slip-ons. The performance is much better.

 

I was told the same thing by my Dealer service guy. But I was also told there was not much good in doing it without changing the mufflers and doing the ECM download . I did the stage1 w/K&N AF. I wasn't satisfied with the results, So I bought a set of FuelMoto's Jackpot's. I took the bike back and had the service guy check the download to make sure everything was alright. He said he richened it up a little. I like the performance better now. Better throttle response. I might add the PC-V from FuelMoto when hot weather get's here. If I had it to do over, I would get the package from Jamie @ FuelMoto. Great price and service, Those Dyna Tuned Jackpot's are IMO the best sounding and best looking Muffler's out there.
