Air cleaner change
Hi
I talked to 2 different HD dealers about changing air cleaner.
I asked for SCREAMIN EAGLE HEAVY BREATHER.
One dealer said that loading fuel pack is an option and not really necessary (cost 270$)
Other dealer said that it must be loaded (cost nearly 500$)
Now I got a question. How it really is.
Do I need to have it loaded or not ?
For this cash I can buy PC V.
Please share your experience.
Cheers
Piotr

The ECM needs to recalibrated when a free flow air intake such as Sceamin' Eagle stage 1, ventilator or Heavy breather is installed. The Heavy Breather has improved flow and performance over the other 2 listed per HD. The timing is advanced and rev limiter raised from 5500 to 6200 when recalibrated. I had my done since my bike is new and by having HD do it will keep her under warranty. I recommend having this done if you are doing air intake and JUST slip on mufflers - NOT full exhaust. If you are planning on more mods or faulter from intake and slip ons, get a SERT.

I spoke to an HD tech, regarding a/c and slip-ons....his experience, was he's never seen a melted motor, or even one with problems, from simply adding a/c and slip-ons without a fuel pak, or re-map...true they run lean, for emissions, but not much hotter, only slightly due to lean mix...I installed an AN tuner,(which doesnt work), and since it isnt working, havent had any issues either....as was stated, if you plan more mods later(cam, etc), would be worth investing in a SERT, or TTS, but I wouldnt panic about not havin it with an A/C and slip-ons...stealer is tellin you what he has been programmed to say

There is a limited amout of variation that the ECU can cope with, once you are outside this the stock tune will be too lean. This will lead not only to poor performance but also, in the longer term, damage to the cylinders and valves, plus general overheating.
The thing is that these bikes use closed loop a lot from stock and this relies on the O2 sensors which are narrowband sensors i.e. they only work properly around the 14.7:1 AFR. Get the AFR outside that because of increase air flow through the engine and the ECU can't cope.
At a push you can swap out the exhaust OR the A/C but not both. Do both and you definately need to remap. But then I have to ask why anyone would spend $100s on an A/C or pipes when they do nothing apart from risking damage to the engine? Why not finish the job properly and get a map to match?
[quote=Foxster;6713390]Sorry to disagree with you but that's simply not my own experience.

Couldn't agree more. I have had several experiences where I find that I can go cheap initially, but then regretted it later on. So my advice would be to save up some monies and do it all in one big shebang. Sure, its a lot of money, but as soon as you ride her tuned right the first time I'm sure it will all be worth it

thanks for all replies.
The thing is that it is not about saving money. It is about how to spend them wisely and do not get ripped off.
Could anybody tell me how much it is in USA to load HD fuel pack at the dealer shop ?
Here in Poland they are crazy the price is 270$ at one shop and nearly 500$ at other shop.
