So I've had my '07 Ultra for just over a year now and just approaching 30K on the clock, with just over 10K mine. My bike was purchased with the stock headers with Rinehart slip-ons. Not long ago I replaced the stock headers with V & H True Dual headers due to a cracked "Y" pipe. Kept the Rineharts and like the way the bike sounds and feels. However I am noticing, with increasing frequency, a ping while under load and in the higher gears. I never noticed this before, and am wondering if the Stage 1 download would be adequate for the new headers? Is the Stage 1 taylored in any way to accomodate different exhaust or is it the same regardless?

Other question, although I really can't afford it right now, would a fuel management system like PCV or other, eliminate this condition?

Thanks,
Dan

 

some of us are happy with nightrider.com xieds.

about $100

if there was no ping before, yea you probably need a fuel management system and a tune. I know it's pricy but the tmax w auto tune fixed my pinging with slight adjustments to timing.

 

How much is a slight adjustment, I assume you retarded the timing, by what, a full point, 2 points, less than a point?

 

two degrees took care of it.

 

While the XIED's have helped, they have not in any way eliminated pinging on my bike. I run Rush slipons with no fuel management system.

 

The ViED will let you adjust to a bit richer than the XiED. Check HERE for the details.

 

When you say Pinging do you mean the pop pop on decel ?

 

No, it sounds like your lifters are making a racket. hard to tell the difference.

 

No, I mean detonation. I do have a little bit of decel pop but that's not what bothers me. It's the detonation and what it may do to the pistons.
