After checking everything and trying new sensors I still get a check engine light and codes indicating that my sensors are lean.
I'm now going to take them off an run without them.
I'll let Steve at Nightrider.com know what's going on.
The bike starts fine then after it heats up I get the codes and it runs a little rough.
Oh well.

I sure am sorry to hear that. I haven't even installedthe DYN OiED's I bought for my 06 Street Bob yet because I've been waiting to hear if they're working without problems for anyone, and I can't see that they are.[sm=sigh.gif] Still hoping to hear a success story from someone though.

 

I emailed Steve at Nightrider.com, I'll let you know what he says. You might want to try them anyway.

Here's the reply from Steve...

"Mike;
These are false codes and do not hurt the engine. The lean code is generated
because of the way the ECM is programmed and the voltage shift of the IED. I
can assure you that the bike is not actually getting lean. The stumbling you
hear is when the bike temporarily goes into open loop mode. For most bikes,
these only lasts a few seconds and then the bike goes back into closed loop,
running just fine."



I'll have to leave them on and go for a nice long ride to feel what happens.

 

This is good news!!

I just installed my DYN OiED's and was getting the same code:

P0131 Front 02 sensor low (lean)

I took the bike for a spin around the block and unfortunately for me the blasted surging is still there. Granted, it is definately less than when I was running with the PCIII or stock so it looks like I will give the DYN OiED's a shot for awhile.

My next Harley will have a carb and not this EFI crap.

 

Mike,
Thanks for following up with Steve's reply. Interesting.[sm=confused06.gif] I still haven't decided if I'm going to install them or not. I don't like to "tinker" with the bike much, doing things and then undoing them, so I'm still in a holding pattern.

 

Luckily all you have to do is plug them in, it's not like pulling the stock air box and installing an SE one then redoing everything.
Pull the seat, undo the voltage regulator and plug-in and done.

Mike
PS- I'm getting quicker at it.

 

Installed Vance & Hines Straight Shot slip-ons and Night Rider IED's on my 07 Street Bob and it runs super smooth seems to have more power and good throttle response, still get small pop on decell once in a while, but thats it. I would say they work but I would also say if you want to know for sure, get a dyno.

 

Sorry, but you might not like to hear this, Stumbling?, unnacceptable, there is no reason you should spend your hard earned cash and have a CEL and stumbling, you must remember the 06 Dyna is a unique system, unlike the 07 is does not have the adaptive fuel feature. Also, if you view data logs of an 02 equiped bike you would be suprised just how much they run out os cruise where they do not incorporate the 02's My 06 dyna stock ran like crap, surged so bad I thought I must have been twisting the throttle or something, do yourself a favor, get a decent tuner(SERT etc) and find someone who knows how to use it, you will think you have a different bike. Also, the 06 dyna when tuned with a SERT will accept maps that are all open loop and can be tuned accordingly, eliminating the 02 funciton all together, I really don't see the advantage on an 06 dyna ecm in running the 02'swithout the adaptive fuel feature, Sorry if this sounds harsh but I thought the explanation from nightrider was pretty lame. Good luck in whatever direction you choose.
