My fuel mileage didn't change at all once I added the mods. I've been checking my mileage at every fill up since I got the bike.

In regards to the O2 sensors, V&H says to leave them connected.
The PCV comes with inline O2 eliminators. From what I've read
most tuners dont use the stock O2 sensors. Tuners with "AutoTune"
features come with a new set of closed loop sensors. Man, there's
just toooo much info out there. My head is getting close to exploding.

I installed a fuel pak on my '11 WG with big radius and SE Heavy Breather and it ran really rich with a lot of popping/backfiring so I removed it. It doesn't pop any more and I cant tell any difference in the performance. Might try a PCV and see what I get outta it.

There is a setting value that can turn off the fuel to eliminate decel popping, however mine runs better leaving decel fuel on. I can give you the value and what increasing and decreasing do tomorrow. I have never heard of a rich problem before,but thats only my experience.

Not really a decel pop. It's popping while up shifting between gears like its an afterburn in the exhaust.

You have to completely let off of the throttle between gears. It takes a little bit to get used to but it does make a difference.

Pretty big number changes from what was originally listed.
It'll be interesting to try them out.
Also noticed there is no question regarding what type of intake you have anymore.

Here are some notes that I came up with after a long talk with a Vance and Hines tech. Originally I had some rideability issues regarding a ON throttle pop that would show up ONLY after NO throttle deceleration.
Basically the bike would pop when the Fuelpak would turn fuel back on after the deceleration. So after calling Vance and Hines and picking their brains I was told that they have set a decel fuel cutoff into the Fuelpak to rid the bike of decel popping which so many people complain about. The problem with this is that every race engine I have EVER tuned for track use I actually did everything in my tuning ability to RICHEN the deceleration fuel whether it be modding the DECEL ENRICHENER spring on carbs or adding LOW RPM fuel on the ECU on FI bikes. What this does is keeps the valvetrain cool and keeps the engine ready for a twist of the fuel, eliminating any sudden drastic effects of the engine upon the first twist of the throttle. OK SO...

The tech provided this info and this can be applied to any map you run. On MODE 23 which is the circuit that controls decel fuel. This number can be increased up to 25 and WILL cause decel popping as you are allowing fuel into the engine upon deceleration. Like I stated above I LIKE decel fuel in my setups as I dont believe starving an engine so it doesnt cackle on decel is proper tuning. I found that all of my rideability issues went away that I had experienced in above statement. So I encourage all who have the Fuelpak to increase this value to 25 just to try it, from there you can dial it back a little at a time and tune to your likeing to control the AMOUNT of decel popping you can deal with. I left mine at 25 because I care about how my engine runs and not how it sounds. My bike has a slight cackle to it on decel, and it never has a BIG POP like it did before resulting from a 13 value in MODE 23.
Try this and report your findings with a given pipe/baffle/ and air filter setup so others may benefit as well
I use FP1348 with Short Shots/open baffles/ Arlenn Ness Big Sucker. Value 25 in MODE 23
I hope this helps you guys with the Fuelpak as I was originally gonna throw it in the trash after 3 unsuccessful maps, and the problem was all in that MODE23 settiing value. I am Happy and saved a ton of dough not needing a TTS.

I had some decel poop with slipons, changes to full exhaust and emailed my setup to V&H and in two days I had the right map. Also on V&H website it states that mode 17 will adjust the amount of fuel.

Diagnostic Mode Explanation:
Mode 17: Adjusts AFR (Air Fuel Ratio) for warm idle – a positive number increases the amount of fuel and a negative number will decrease the amount of fuel. Changes are made in real-time, so you can adjust this number with the engine running and immediately see the results of your changes. This will change AFR at warm idle only, it will not change the AFR at other operating conditions.

No motor work for a 2-3 years

Hey Toplink I looked on the website and cant find any info on that MODE 17? What were the minimum and maximum values that can be used here? Did you play with the value here? What were your results and affects of the changes?
