I was just looking over the S6 programmable ignition. The manual just says that a suitable curve will be provided. Then there's a USB flash drive which has a program (Andromeda) and instructions for the program as well as some curves. Here are the curves on the drive :
I have a 592 CDI. I assume the second number in those is windings? That's not explained anywhere. I don't see anything but ID # 1042 on the stator, which matches nothing, so I assume they expect me to use any of the 592 curves. None of the curve (for either CDI) look spectacular to me. Maybe I'm wrong, but if these are the curves that S6 is putting into their racing ignitions I'm a bit surprised that anyone likes them. Timing at peak power is on par in 2 of the 3, but they really pull out all of the advance at lower revs compared to MVT, Malossi or general 2T advice that I've seen. Most have 30-35 degrees peak below the powerband, with MVT going wild at 42 degrees with the recommended timing on mine (why I wanted to move on to a new ignition).
When looking at these, you'll see EIT and LIT curves as well. That's something I'm not used to on timing graphs. EIT is Earliest Ignition Timing, LIT is Latest Ignition Timing. Those lines are showing you the constraints of timing, which depends on where the rotor and stator are set relative to each other (mechanical timing). The green line represents the mechanical timing. The red curve is all you need to look at for the provided curves and there's generally plenty of room to work with the curves between EIT and LIT.
The good news is, it seems easy enough to make a new custom curve. There's also an interface box so USB files can be transferred into the CDI. Not sure if that has any stored data or what (if anything) is loaded into the CDI as standard. Maybe that's got a better curve on it?
I also noticed that the instructions say to use the woodruff key and install the flywheel that way. It's for Piaggio, not the RC-One specifically. I have no key so I may need to look over things better or I suppose I'll be guessing at it's placement (don't have a Piaggio crank to know for sure where the key is supposed to be relative to TDC. I don't know that it matters much as long as I can get the stator and rotor to allow a 10 degree mechanical setting without being maxed out in either direction.
I'll probably quickly lap the flywheel and crank for a little extra insurance since I can't use a key as intended, but it's never been an issue for me with the MVT.
Not sure when I'll get to iggy stuff, but there's a peak at what's provided with Stage6's new programmable setups.
