Please help Air intake and exhaust questions
If you already have the stage 1 useless ecu flash, can you still add xieds to further richen it up.
To be honest when my bike was tuned in Spain, and I ended up with a 96c.i. map it ran cooler than it does now with the 'correct' 103 map, so I think they started with the 96 and altered it. I did see them with a lap top and the screen with the mix values open for a while. But it's quicker now, so it must have been running a bit rich.
Anyway, stage 1 and Xieds ??
Yes, a rain sock will keep it protected from pouring rain, whether it is sitting or riding down the road. The Bobber covers will also keep it protected if you prefer that look.

The ViED is probably the best choice. You can see details on it HERE or HERE, depending on what year Softail you have.
The PV is a flash tuner, meaning you hook it up temporarily to your bikes Diagnostic port and it flash tunes your ECM with a MAP [which incidentally can be pre-installed by Fuel♣Moto] that will closely match your current level of modification[s], ie., intake, exhaust, etc. And if you want to take it a step further you may utilize the "Auto Tune" feature of the PV to create a new MAP simply by taking your bike out for a 30-100 mile trip, taking the bike through it's paces while it learns your riding style. You then save this new MAP and flash it to your ECM and you are one iteration towards damn near the best performance possible by yourself. The PV will ELIMINATE the factory lean condition that exists from the factory and from you adding a free flowing exhaust and intake, by optimizing the Air/Fuel ratio to that of proper combustion in it's current condition, which will lower your engine and exhaust temperatures, it will smoothen and increase your rate of acceleration, and it will eliminate any decell popping, all at the cost of a few miles per gallon. Your bike will even SOUND better.
Unlike some other tuners, the PV tuner DOES NOT have to be piggy backed to your ECM, so you don't have to find a place to hide it. Once you are done flashing the ECM you can remove it and be on your way. OR, you may keep it attached to your Diagnostic port and mount it to your handlebars/wherever and use it to display just about ANY data point your ECM is utilizing, ie., cylinder temp, or you can display your RPM in a number of different formats, etc. Its 3.5" touch screen LCD display helps in programing and option selection, along with its ease of display/setup attibutes.
What's not to like about the aformentioned? Oh yeah, the price, which sits at $499. But think about what you're getting...its display, its ability to Auto Tune, its ability to be disconnected so you don't have to find/make a place to hide it, the FREE MAPS, lifetime support and double the factory warrantee you get if you purchase from Fuel♣Moto, the ability to save yourself the cost of a two+ hour DYNO and tech bill, the ability to easily "upgrade" your MAP configuration as your mods increase/change [ie., when adding cams, big bore kit, etc.] without the associated cost of yet ~another~ DYNO and tech session...just to name a few.
Sure lots of guys say they're "happy" with snake oil products like the XiED's but if you look deep into the subject you will see how many have silently switched to an actual tuner, be it the HD SERT, Power Commander, Fool Pak, the PV, or even the ECM replacements which are the most expensive. So why do so many people buy the XiED's instead of a tuner initially? Because while they're in their motorcycle infancy and before they have learned better they just have to have something, something that is, until they finally wake up to the idea that the snake oil isn't all it's cranked up to be. How do I know this? From the many many XiED's I see for sale on CraigsList and eGay.
I've got an advantage in being old. Over the years I have learned many a hard lesson about that dollar burning a hole in my pocket and how to put aside my feelings of I-gotta-have-this-thing-right-now-even-though-it's-not-what-I-really-need-or-it's-a-waste-of-money. Becoming smart in the financial arena prevents one from furthering unnecesary and wasteful spending habits. Hence, when I went out looking for a better running machine and an answer to the pesky factory lean condition I did my homework and got edjumicated...and I didn't just take anyone's words for gospel here or elsewhere, I found out myself, and after weeks of hankering back and forth I finally had enough information to make an informed decision, and that decision landed me at the Power Vision tuner. And since I've been running it, my bike runs smooth as $hit and I haven't had one issue, and to the best of my knowledge, neither has anyone else in this forum who runs the PV tuner. We're just a bunch of happy campers.
So do yourself some homework and look into the tuners, all of them. A good one will be well worth the investment I assure you...in the form of an initial monetary investment and secondly as an investment in your own knowledge department, and who doesn't wanna' add smarts to their knowledge base along with having a bike that runs like ****???
P-O-W-E-R V-I-S-I-O-N.
Did I mention Power Vision?

The a/c uses info from the O2 sensors, so the ecm will set the A/F to <>14.6 including info from the a/c. Slip ons sit past the O2s and the ecm cannot fully compensate for them, but slip ons don't do a whole lot. Remember, you are only changing closed loop (idle and cruise.) Any time you are "twisting," the bike is going into open loop. So, many people think you aren't going to do any long term damage adding just slip ons and a/c. But, remember that 14.6 <> is the A/F mix for best fuel efficiency, not best performance. You may also want to reduce decel popping or change the idle a little, etc. The XIEDs fool the bike into a closed loop A/F of a set number, like 14.0 to 1 AFR. Tuners will allow for a wider range, depending on anticipated load.
So, for what it's worth, here's my advice: ride with just the slip ons and a/c. See how you like it. If it feels a like you want a little better performance, get some used 14 XIEDs off ebay.
Want more performance after that? Look into a tuner. I have the Powervision; used it on a Sportster and now on a Dyna. I would not trade it for anything else.
