Ignition Timing Advance Curves
#11
hmmm- yeah the ECM is supposed to retard when it detects preignition...but, my 09 pinged in completely stock configuration
repeatable 2800~3200 rpm up a 6% grade.
that was my impetus for the xieds- which fixed that, then allowed the hi flow in/out.
the ping is dead.
I think if you can chart where you have ping problems in the rpm range, then guess the throttle position and vacuum- you could then address that range a cel at a time until you find it.
Seems like a fun challenge---- when I was at santa monica college they had an aged old distributor curving machine. you put on the distributor and swapped springs and weights to get the desired curve...pull a weight off, dremel it...too retarded, you weld a bit of steel ont it for weight...
then get an adjustable vacuum motor for the advance..
spent many happy hours there putting late model HEI ignitions into my old chevys and cadillacs

Does anyone have or know where I can find the factory ignition timing advance curves for a 2011 FLHTK?
I'm playing with the timing curves on my bike utilizing a Power Commander V (PCV) which I can adjust up or down in one degree increments at various rpm and throttle positions, but I have no way that I'm aware of to determine what the baseline is.
Any help would be appreciated.

2010 streetglide timing on PCV
ke5rbd, first off i know this is an old thread. That being said, I've been doing some "tweeking" on my 10 SG 96ci andrews 48h V&H pro pipe high-flow ac. I came across a map you shared for a similar set up. You seemed to be the man when I comes to tuning based on comments I read. I loaded your tune into my pcv and before starting it I looked through the fuel and ignition maps looks good to me but the ignition map is pretty radical. As much as +9° adv. In some places? Is this correct? Any schooling you're willing to do would be much appreciated. I live at sea level if that matters. Thank you for sharing your knowledge.

Thanks for the heads up. Having a hard time locating a ignition timing map for PCV on my 10 streetglide, 96, 2into1 pro pipe and Andrew's 48H cams.
all that I find are those generic advance maps that have big blocks of ranges with the exact same advances.
I'm new here. Any suggestions on people I may be able to contact or message?

There are a few guys who do some tuning on the forum. As for who would be THE GUY to contact, that's a hard one to say. I just don't know. Jaimie @fuelmoto has replied in this thread already. The folks at FM have always been helpful for whatever I've needed.
Keep an eye on this thread. Perhaps Jaimie or someone else may chime in to add some info soon.
