There's 4 advance curves to choose from on a Dyna 2000 ignition, you'd want the lowest possible but it say's that for modded motors, high temps and crap fuel you'd want curves 3 or 4.

Now I'm wondering what fuel you guys get over there, so I can determine what Dyna means with crap fuel...

Over here hte minimum is 95 octane, 98 octane being my regular and 102 octane a possibillity...

I'm using the dyna on the Superstock 96" so I guess that counts as a modded engine, but I'm not sure if I should use curve 3 or if I could get away with curve 2...

 

If no ping, then stick with what works the best.

Sounds like you have great fuel in Holland....our "regular octane" is 87, and "mid grade" is 89, and the "premium" is 93 sometimes 94. On rare occasion we can find "racing fuel" at around 104 octane.

If I remember correctly, curve number 1 is the highest (or most) degrees of advance and comes up the earliest, fastest, highest. Switching to 2 retards a little and comes up slower, then 3 a even lower and slower, with 4 as the most retarded.

The dyna 2000 instructions don't show the advance curves in a graph, but the ultima 53-644 manual (link below) does and is the same unit with a different label. And a few links on timing, reading plugs for timing, etc

Start with curve 1 and if you get pinging goto curve 2.
If you have pinging with curve 2 then go to 3, etc...

If I remember right curve one is a bit of advance from stock and 2 is the stock curve.

 

Your memory is right on the money. You bring a lot of knowledge to the forum.

 

With 95 octane (which is awesome) curve 2 will do you well. I am not a proponent of the voes. To me all it does is promote detonation at low rpm tip in's, in and around 2000 rpm...

 

I don't run VOES and it's on 98 right now on curve one...runs strong this way and I haven't heard it ping...yet!

 

Then leave it the hell alone and ride!!!!!!!!!!!!!!!

 

My thoughts exactly!

I like the way it rides now, over here speeds are higher than over there and I tend to 'override' the bike a lot, it's fun to hammer around a big old sofa!, and this engine likes to rev more than the old one so job's a good 'un!

 

If you're talking about speed limits you are probably right.
If you're talking about the speed we actually go then I doubt your speeds are higher!!!!

 

Fair enough haha!
