Aircleaner, pipes and EFI

bernhardz77

Hi everybody,

I am looking into changing the stock air filter and pipes on my '09 SG. I am looking at the Kuryakyn Hypercharger and either Screaming Eagle or Reinhard slip-ons.

I have a couple of questions.

1. What third-party components void your warranty? The Reinhards claim an increase in horse power, so one could make the argument that is stresses the engine more than stock.

2. What downloadable EFI maps does Harley have available for it's dealers to adjust to these various components, especially common third-party ones? How critical is the EFI map download when changing these two components?

TIA

Bernhard

No 3rd party product will void the warranty - it is down to HD to prove the product fitted caused the warranty - also look up Magnusson Moss act the web.
A stage one will not stress the motor - the motors are designed to deliver a certain power ie max then strangled by the regs to get them thru noise and emissions.
the downloads are not used by third party tuners like TFI/Power Commander/Kuryakyn Wild things and so on, the down loads are only used by HD dealers as they require the use of the Digital Tech.
best bet to do a complete stage 1 is choose your pipes the Reinharts are a very good choice, pick you air cleaner and your fuel computer

i have thunderheader 2 into 1 and ness big sucker ac and niterider xiedon the o2 sensors on my 08 sg and she runs great

Thanks for the info on the warranty.

I have heard many times that people swap out the stock EFI to a different one such as the PowerCommander or other. However, it seems to me why change a perfectly good working part (except for of course when we have a good reason such as the sound of the pipes) when it can be reprogrammed by the dealer.

Are there other reason why you would switch to a after market EFI controller?

Hey, I'm in the same boat.

I bought my 09 SG last night and the dealer told be to save my money on a tuner. If I was just doing mufflers (Reinhardt slip-ons) and intake (SE Heavy Breather) then the Stage I download would be all I needed. He instantly saved me about $200!

So that's what I'm doing tonight right after work...going to get the download and riding home to install the pipes and intake.

Wish me luck!

Hypercharger are worthless in real world IMO.
Standard SE with K&N high flow filter about as good as it gets

Everything dealer told you is ture.
But there is more to it. The stage 1 makes the stock download run lean all the download does is add 1000 rpms and bring the ATF back to the factoiry lean setting of 14.7:1. EPA prevents HD from going any richer.
Your bike will run fine there and you'll get a little kick from the stage1 parts not the download The 1000 prms are worthless on that bike.
To get he full advantage of power and the most of the little cooling you get from a stage1 you still need to add some fuel.

Okay... Help me out a little here... I have an 08 EG thats stock. Not really wanting to go loud with pipes but would like a little more kick. (Power Comander, Air Filter, and or not)

I would do the TFI and the stage 1. Best bang for the buck and no extra dyno time.

agree,
You do not have to go loud to have stage 1 pipes.
The SE a/c with The K&N filter good bang for the buck
And TFI to manage the fuel you be good to go with no hidden extra cost or dyno time.
