VOES or No VOES
Hi All
My Motor Builder is in the final stages of completing a S&S 113 20thou over hi flow heads and .600 cam,. I have two options for ignitions i have a Hi-4N and a fully programmable Ultima ignition. I have previously purchased a Daytona twin tech VOES with the 6-7 in-Hg switching to be installed on this build.
So as the title say Voes or no Voes?
i note that ultima say with their big cube engines not to run a voes

Could always call S&S and see what they say. I personally feel the voes activated advance curve is a good thing IF it is calibrated for your engine/bike and riding style. It would be interesting to hear what S&S says about using it on their big cube engines. Pinging is not our friend...

True,I think I want to use it as I understand its basic function, I want to learn and understand the tuning of the ignition to get the most out of the tune and the engine. I want to understand custom curves, like you can load using the Ultima ignition(which I have) or a Dyna 2000i but want the benefits of using the Voes during load applied climbing hills ect.....or do I? hence the post

How heavy is your bike? Mine is considered light for a big twin and my Voes is set at around 7 mm hg. The stock setting for mine was around 4 and the bike did not like that with my mods.
With it set at 7 it is pretty much in the advance curve while at a nice steady and easy cruise. Stays in that mode for very slight hills or acceleration.
Any time I get on the throttle it drops to the lower (retarded) curve. It gives me piece of mind.
I use an indicator light (simple circuit) to tell me when I am in advance (light on) or retard (light off) curve, so its easy to tell how things are working and how the adjustment to the voes is performing.
The indicator light is no longer needed once you get things dialed in to your liking. It takes a little time to tweak seems worth it to me.

Are you running a Programable ignition?

if you are going to have the bike professionally dyno tuned, yes use it and have it set up correctly.
if you are not going to have it tuned by a pro, i would say dont use it.

I'm also thinking the VOES curve is a good thing, that's the way I'm leaning, I've done a bit of reading over the last few days and now i think I've got my head around the "Part Throttle" & "Full Throttle" curves, I suppose I step it up a bit now and reach out to the "tuners" amongst us and start to look at what the advance @ RPM some people are using in both Part & WOT. and to refresh im talking about a 113 with full head work , flowing 305 on the intakes and 285 on the exhausts, port matched manifold and a 48 mm Mikuni
