I used a frame bolt for the front Xied and the negative battery terminal for the rear one. I consistantly get 44-45 MPG on the road. If it hurt the gas mileage I can't tell it. Like princeaz, I can run 6th gear more now and at lower speeds so I know the bike is pulling stronger.
Hey guys.....I see a bunch of you with these....are you running with stock headers or are any of you running with an aftermarket header/guttend header.
This might sound naive too but when grounding is there any special precautions to take when performing the grounding? Seems to me if you can ground to the frame that is the way to go. If you ground to negative terminal is there any chance of sparking? Just trying to avoid doing any damage to the electrical system. yes I had a bad experience with a battery once before so have been a little gunshy when it comes to this sort of stuff
I am running the stock 09 headers, no cat in the 49 State version. and hi flow tuned mufflers.
there are no precautions to take when grounding anything to the bike. for my application, the front is grounded under the regulator mounting stud and the rear is grounded under the starter end cover--- I have some other wiring stuff going on and the battery terminals were a little crowded under the seat
Port Dawg,
here is a tip for next time you find yourself staring at the battery with a wrench in your hand...
if you disconnect the negative battery terminal first- then you can disconnect the positive with out worrying about your wrench throwing sparks if it hits the frame.
when you are installing a battery, hook up the positive first- THEN the negative again, no worries about throwing sparks if your wrench hits the frame while tightening the bolts.
unless the ign switch is on, you should have only the tiniest of spark when connecting- that is from the memory power for the radio and the sec system.
with xieds my typical mpg has dropped from 44 to 43 MPG tested over thousands of miles.

So basically I can undo the negative terminal and ground the VIED's without any issue with sparking? If the negative cable happens to touch the frame will it spark?
Again, not much experience so just asking which may seem some pretty basic questions

i still have the stock header with the Cat in, and don't have any problems, i grounded mine to the frame, the one thing i did have to do was replace the ground ends on the XIEDS, they were to small to go threw the frame bolts. but so far so good I'm happy with them.

the ground cable is fastened to the frame so no chance of a spark . but don't let your wrench hit the pos terminal when you are taking loose the neg terminal . the xieds I got for my 07 did not have any wire to ground , they must be the adjustable ones , mine were just plug in with the 02 sensor and go , the $99 ones and am very happy with them , running fulsac duals with rush slipons and a se breather
I believe all the the newer models come with grounding straps, both Xied and Vied's. I grounded mine the the battery since it was right there where the O2 connectors are anyway.
The XIEDs add about 8% in the closed loop portion of fueling. Overall 5% seems reasonable...
OK, I'll ask...
(1) Do you know what part of the map for your bike (or any for that matter) is set for closed loop operation? Do these devices continue to add fuel even under accel enrichment?
(2) How do you know your bike needs an additional 8% of fuel?
(3) Do these devices take into account your particular motor's VE's, timing, or even the quality of fuel?
