being my bike is in the shop . i thought i would go ahead and have flashed for the stage 1 but the twist here is i do have slip on S.E mufflers on her and i plane on just putting in a K.N. filter in the stock air box will the flash hurt any?

 

My understanding from others is you want to have the flash done when you install a high-flow air cleaner setup. If all you had done was just the mufflers getting the flash done is not really needed. It's the additional air that will require additional fuel to be added to the engine to get the correct air / fuel ratio.

Now, there are those who do not recommend the HD Stage 1 Flash and label it as worthless and will recommend adding an aftermarket management system like the PC IIIusb or the SERT. Personally I did both the Stage 1 Flash and added a PC III. This allows me to remove the PC III if needed (like a trip to the dealer) and still have the bike run decent. In fact I currently have the PC III unhooked and running just the Stage 1 ECM. The bike seems to be running better in the cooler weather and I'm getting a little better fuel mileage. When the temps warm back up I'll reinstall the PC III. Does that make logical sense? I couldn't tell you, but I CAN say it works for me.


Hope this helps,
Brian

 

You must have a f.i. bike besides your namesake...a 2003 Sporty? If so, then yes, you will need to do something if you change the air cleaner to a hi-flow type.

 

solorider i got my handel when i had a sporster since july i bought a 05 super glide yes with F.I but i'm just putting a air filter in the stock box . thanks for thr reply but you know a dyna is pretty sporty in it self just with a whole lot more grunt.

 

Yup, my bad...was just over in the Dyna section and saw your post about your bike. Good luck with it!!

 

Get it flashed. It won't hurt anything and your bike will run a lot better with new EFI settings. I have an '06 Dyna with SEIIs, and stock air filter. When I put the pipes on it, I noticed that it seemed down on torque and just didn't perform as well as it should. I got the Stage I flash and the difference is remarkable. I still have the stock air cleaner and might upgrade to the SE air cleaner, or I might not. The bike runs great now.
