Screaming eagle Nightstick for 2 into 1 2010 flhx

[quickster]

I heard this exhaust today and it sounded pretty good. I just wanted to change out the slip on. Some dealers say you can do this with no problems, other say you need to tune with the power commander, EZFI Tuner, fuelpak, maybe change air filter type.

Is anyone using this Nightstick without spending another several hundred dollars.

thanks

Yes, I have one its the SE muffler fo the Street Glide, Road Glide, the book says you dont have to remap, unless you also change air filter. Feels a little better.

Agree there!!!!

The Harley fuel program is quite lean in stock form, if you do anything to increase the air flow through the engine, you should do something to adjust that program to get the engine to run correctly.

If all you plan on is the stage one air filter and free flowing muffler, the Fuelpak from Vance and Hines is a good low cost choice.

Leonard at D&D told me "the 09s & 10s don't need to be tuned with our Boss slip ons or Boss 2:1 with a hi flow air cleaner".They will run fine except ,the CLOSED LOOP will maintain the EPA 14:7:1 A/F requirement.I also called the HD customer service rep & he told me the Stg 1 map for the 10s has the same A/F map as stock, but does raise the rev limiter from 5500 to 6200 rpm.Also Steve Mullen agrees that a A/C & or pipe change won't cause the bikes to run any leaner than they already do..........& yes I know the TTS is the bomb,but there are a few folks that don't want to go down that road & this info is for them.Regards,Tom ps D&D & FuelMoto have Dyno #s with A/C & pipes,NO TUNING on the respective web sites.

It is only in "Closed loop" when holding speed or idling, as long as all the criteria is met.

The rest of the time it is in open loop and relies on the fuel program to set the fuel ratio.

It will be just fine, right up to the point it's not and you have a problem like a burned piston or other lean run induced problems, and then you go to the dealership for warranty repair and they say, sorry, you failed to correct the lean running and caused the failure.

Will D&D then step up and pay to repair your engine?

The point is if you give them an out, they will take it and any increase in air flow will further lean out the fuel map and since the Delphi computer Harley uses has such a small window of adjustment it is easily overwhelmed.

A Fuelpak will fix this and cost like 250 bucks......and it will run better.

Hell if V&H will pay for engine repairs,....sign me up!That said,your 07 efi/ECU is much different than the 09 or 10's,plus V&H did not have a fuelpak for the 10s last I looked.Regards,Tom ps:Haceienda Harley in Scottsdale made note in my record on my 08 FLHTCU that I had a Fuelpak installed when I took it in for the bad batch of fuel filter caps that were cracking & you are right....They tried to blame the sputtering on the fuel pak.

2010 Harley-Davidson FLH / FLT Bagger motorcycles: D&D 2 into 1 Boss Fat Cat Exhaust pipe.
PIPE OPTIONS
- Black Pipes
* 556-31B - With back cut tip
* 556-31L - With slant cut tip
- Chrome Pipes
* 556-32B - With back cut tip
* 556-32L - With slant cut tip
Note: (Slant cut works with the CVO Extended bag models)
PERFORMANCE KIT
Increase your performance by adding a Zipper's HiFlow Air Cleaner. The D&D exhaust system with a Zipper's air cleaner is the biggest bang for your buck. Note: ZIpper's air cleaner requires an additional investment.

NO TUNER
The team at D&D spent hours on the dyno testing the combination of a high-performance air cleaner with the BOSS Fat Cat pipe to ensure no tuner download is needed.. With just a wrench and a ratchet, every 2010 bagger owner can be up and running within an hour. That saves time and money.
At idle, the motorbike is deep, boomy and full of character. Not only does the pipe look good, it is a wonderfully sounding experience for the rider.

I see that Jamie does have a PC on his Dyno sheet for the 10s.My mistake.Regards,Tom

The OEM system will adjust to run the SAME afr as stock with the pipe change. Yes it is EPA spec lean during low throttle/rpm, when you crack it goes into 'open' loop, dumping more fuel into it.
Could it be tuned better? Yes. Is it a requirement, No. Will it 'burn a piston' no.
