swepzz Posted August 6, 2009 Report Posted August 6, 2009 looking to advance my timing some and was wondering which would be better off and why? a new ignition seems really easy to install opposed to tearing apart the fly wheel and stator and such so yea...? whats up with it? Quote
J-Madd Posted August 6, 2009 Report Posted August 6, 2009 A timing plate is cheap and takes less than 30 minutes to install. A programmable ignition is expensive and take 5 minutes to install. If you plan on making your own timing curves, it take a lot longer than that. Quote
Snopczynski Posted August 6, 2009 Report Posted August 6, 2009 I personally hate riding bikes with stock timing curves in them after owning a dyna. It doesn't just advance the timing, it changes the entire timing curve, so the bike runs different over the entire rpm range. I would rather be shot in the dick than run a stock cdi ever again. :biggrin: Quote

swepzz Posted August 6, 2009 Author Report Posted August 6, 2009 Does it come pre programed or do you have to mess with it? hehe im pretty sure im about to order one right now. reading up on it trying to figure some stuff out about it... from what i gather it stores 4 different curves and has a selector switch of some sort? seems tits to me, figure why not...

swepzz Posted August 6, 2009 Author Report Posted August 6, 2009 heres a link to a pdf from the manufacturer. sounds like it provides alot of flexibility and fun. http://www.dynaonline.com/skins/downloads/...ruct/DFS7-1.pdf i think im sold. Quote
dajogejr Posted August 6, 2009 Report Posted August 6, 2009 Some of the fastest and best running bikes in the country use OEM CDI, Coil and just throw on a timing plate. The dyna CDI out of the box is ok. Unless you plan on spending another few hundred for a cable and software for a laptop, then dyno time...I think a dyna CDI is worthless. I had one, I'm back on a stock CDI now. A dyna has a lot of potential if you have the time and needs for one. Tach output, different curves you can program (Nitrous, alky, gas, etc.), stutter box output....etc. But just slapping one on vs. buying a 50 dollar chariot timing plate, I'll take the plate and save the rest towards a solid port job. If you plan on removing the flywheel, you'll have to buy a thread in puller which is 10 to 15 bucks...and I use an impact and red loctite on the flywheel nut upon reassembly. Quote

They come pre-programmed with a selector switch, or you can make your own curves with the programmer kit. Daj, as the fastest bikes in the world do use the stock cdi, they also operate at one rpm range WOT! Being a low-mid guy, I have seen a huge difference between the stock curves, curves the cdi comes with, and curves I have made. It definitely makes the bike more peppy. If anyone needs a curve made, I will do it for an initial charge, after that if they send it back for another re-program, all they have to do is pay for shipping. Thats how much I would stand behind the dyna cdi. I have messed around with them enough, to where if someone gives me the list of mods on their bike, I can build them a pretty good curve to try. If anything, I can even take the stock curve in the 4th slot and add timing advance to it as well as a backup. Quote
dajogejr Posted August 6, 2009 Report Posted August 6, 2009 Fine point about the fasest bikes Snop, fine point indeed. May I counter... I had one on my 4 mil cub, it was setup as a duner. In the dunes or at the track, I couldn't tell a difference in racing or by time slips one curve from another...and I'm talking about the factory curves out of the box, never programmed. I just think porting should come first, it doesn't sound like this guy has any.... Quote
Snopczynski Posted August 6, 2009 Report Posted August 6, 2009 Odd, we could definitely tell a difference in how the bike ran between all the curves the cdi came with. When we were in Utah last month, We were riding the 4 mill, and had the laptop setup. I would swap out curves and he told me which one seemed the best setup for him. So both cases we have seen a difference that was definitely noticable. Porting is definitely the best bang for the buck mod next to pipes. Cdi's and timing are just easy things to do that rate a little further down on the scale of difference. Quote
Alex29573 Posted August 7, 2009 Report Posted August 7, 2009 a timing plate only changes timing at WOT? Doesnt it advance timing all the time by whatever you set it at? do you guys do timing advance keyways? this is even cheaper... Quote
Snopczynski Posted August 7, 2009 Report Posted August 7, 2009 Doesnt it advance timing all the time by whatever you set it at? Yes. You can manipulate the whole timing curve on the dyna. Drag bikes, which are the fastest banshees there are, are ridden around only max rpm. So there is not really a need for a custom cdi curve map. Keyways are bullshit, stay away from them. Quote
AKheathen Posted August 7, 2009 Report Posted August 7, 2009 (edited) mind if I interject? i did notice going +5, that i gained alot of mid and mid-low, but lost some topend power. if i had a cdi, i know i could go as much as +7 on the bottom, +4-5 in the mid, and somewhere around stock or retarded on the top. this way, i could push the limits for bottom and mid, while still staying somewhat safer in the topend, where i'm most likely to detonate. plus, some smoother running @ and near idle. i'm gonna try bugeting a cdi soon. i thaught u were selling the cable/software, snoop.... whoah, 2 more replies. that's what i get for posting and watching a movie. btw, how much u charge to program?

dajogejr Posted August 7, 2009 Report Posted August 7, 2009 That is correct. A plate is a static advance across the RPMs. The CDI, stock or otherwise, controls the curve. Realistically, you want more timing in the mid and bottom...and less up top for more overrev and peak RPMs. When I had my Dyna, I used all the curves AND 8 on my plate.... Quote
