Dyna Ignition
Discussions on the forum indicate that the Dyna ignition module had little, if any benefit unless you had added cams in addition to air intake and exhaust mods. Some Quotes:
-- "There's really no good performance reason for upping the rev limit because the stock system already allows you to rev higher than the peak of the torque and horsepower curves. If you do mods which move those curves higher into the rpm band you might gain some performance, but with your current setup the extra revs will get you little or no real-world performance gains."
-- "The biggest advantage of the Dyna on a mostly stock bike is the ability to adjust the rev limiter." (see note above)
-- "When looking at sources for Dyna, I came across a rating on Cruiser Customizing, indicating that the Dyna module was a cheaper way to replace a failed stock module that getting a stock module from Yamaha. So, take a look to see if this may be true for you if your stock ignition module fails."
Dyna Settings
It appears that most are running curve 5 set to 7,000 - 7,250

Dyna Settings With Cams - SS Custom Cycle
We suggest starting with curve 6 and trying curve 5 as well (TPS disconnected)
429 .... 7000 Max rpm
502 all......... 7500 Max rpm (8000 with NOS)
TPS
Forum thread on Using the TPS with a Dyna Ignition Module
Forum Discussion - TPS With Dyna 3000
There is an on-going discussion about whether to disconnect the TPS (Throttle Position Sensor) when using the Dyna Ignition module.
Dyna says to keep it connected as the TPS provinces advance during the lower rpm range. Some folks have found that disconnecting the TPS (at the wiring harness plug!) has helped with a hanging idle problems and others with excessive kickback.
Shane, SS Custom Cycles, says to run with it disconnected if you have internal mods like cams or pistons installed.
Also appears that running curve 6 is providing "seat of the pants" more power and definitely smoother running - again for cammed or piston modified bikes..
