Thats what I think to WOT is not closed loop if I remember right so the Xied's are not in the picture??

 

No codes with either IED's or XIED's.

 

Here&nbsp\\;is the response I received from Steve at&nbsp\\;Nightrider.

It would have been very nice to see the RPMs for this run, but I'll make
due.
The fuel might be a little rich in the lower RPM range by about .5 AFR. I
prefer to see about 12.5 AFR on WOT runs. But I wouldn't be overly concerned
the minor differences. That slightly rich mixture is because of Fuel Pak.
Because the XiED's can not impact the fuel mixture at 100% throttle, the
fuel mixture is being set by the interaction of Fuel Pak on the OEM fuel
map.
What you want to know is what the fuel mixture is a 20%, 40% and 60%
throttle at 2000, 3000, 4000 RPMs. These AFR values represent what you
experience during normal riding. The full throttle AFRs on the dyno sheet
represents less than 1% of your riding.

I am going to leave it as is, I am getting 38 to 42 mpg and the bike is running great.

 

I have thrown no codes with either the IED's or the XIED's. My mileage has been running between 42 and 45 consistantly over several fillups.
I just changed my A/C to a HD1499 and used "AZ Chucks" air box mod to open it up for more airflow. I expect this may have some effect on my fuel mileage.
I will be leaving on Friday for a ride to Texas so I should get a real good over-all performance read over the next week.

 

I took a 300 mile trip saturday, and coming home at 70+ MPH, I was getting 50 MPG! I was very suprised. That is with 07 Street bob, XIEDs, V&amp\\;H sip ons, stock filter, and P-0131 and P-0151 codes . Normal around town riding, I have been getting 40 avg. &nbsp\\;

 

&nbsp\\; My Bike has run the best with the XIED's. I haven't even bothered to check or care&nbsp\\;to see if it's throwing a code or not. My check engine light isn't coming on, I've got a nice light coating of soot on the end of the pipes, and my butt dyno is in it's happy place.
&nbsp\\;
&nbsp\\; In fact it just came out of service and not a word was mentioned about any codes. I even left the XIED's on and they even wrapped them up a little better for me.

 

Gundog, just give the 02 Eliminators a try, will not hurt anything. I am running them now and find they work well, but I would prefer the XIEDs.&nbsp\\; Doc

 

I finally went out today and checked for codes. Sure enough, I get the 131/151 lean codes. Though my bike runs great, I am concerned that I might do permanent damage to it. I'm running the IEDs on a stock 08 EGC. Since I don't get a check engine light, I'm guessing that it'll be OK. Any thoughts?

 

MotorMedic I'm in the same boat as you with my 08 Deluxe.&nbsp\\; Let me know if you find out.&nbsp\\; I sent Nightrider an email asking this same question, but I haven't heard back from them yet.

I have looked at this problem and have found that the non-CKE code(s) are set during startup, before the engine actually starts.
For the CKE to lightup, the ecu must have a running engine.
