streetshee Posted August 4, 2004 Report Posted August 4, 2004 hi there,can anyone tell me why are there 3 different dyna fs,1987-94, 95-96, 97-03, is it poss to use an earlier modell cdi to gain more power because i think (if im right) maybe the older shees gave better power? is the new shee a bit tamed down on the cdi? any input would be appreciated....

hamuel Posted August 4, 2004 Report Posted August 4, 2004 1987-94 was the original cdi, 95+ they upgrade the cdi for better spark so i hear and in 97 there were changes in the wiring harness. I could be wrong but thats what i've been told Quote
bradrs Posted August 5, 2004 Report Posted August 5, 2004 There are 3 different ones to match the 3 different connectors and features that came on the bikes. 87-94 had 2 round 4 pin connectors 95-96 had 2 square 4 pin connectors 97- has a 4 pin and a 6 pin connector. The 97- stock ignition switch to the 6 pin connector because they added a parking brake switch that limits the rpms with the parking brake engaged. Other than that, you can pretty much wire any of the stock ignitions in interchangeably with some cutting and splicing. The 97- dyna ignition uses the parking brake switch as the input for its programmable launch limiter, the earlier ignitions don't have this option. So if you wanted this feature, you need a 97- ignition, and a 97- banshee harness with the parking brake switch. You could splice it into a pre 97 harness, but I wouldn't recommend that unless you are very comfortable reading wiring diagrams. Other than the launch limiter, there is no difference in the dyna ignitions, they all use the same timing curves. Brad Electronics Engineer Dynatek Quote
streetshee Posted August 5, 2004 Author Report Posted August 5, 2004 thats very interesting,thankyou very much,i learn summat every day. seeya. Quote
. Posted August 5, 2004 Report Posted August 5, 2004 while your around brad, I've been thinking of getting a dyna for quite some time now. It's got the input for a tach and such. Do you guys also sell the tach that inputs into it? I looked on the site a while ago when the new one with the tach and all was coming out, but didnt see anything. Quote
racer Posted August 6, 2004 Report Posted August 6, 2004 on the topic of tachs: are they all digital or can you get a dial readout model. i cant see any point in a dig. setup wince you cant really see it when youre riding anyways. Quote
23champ Posted August 6, 2004 Report Posted August 6, 2004 While we're on the topic of Dyna, I always wondered how much they advance the timing. Can you program it to the perfered degree? Can it, or will it take the place of an adjustable stator plate? I am aware that it has like three differnt curves, but can you program your own in? If so can you do it yourself,and how hard is it to do. And last but not least, can you program it to have like (example) 5 degree advance from say 0-6000 rpm,(to give you more hp for the holeshot) then have it start to retard from 6000 to peak rpm for more over rev?

Do you guys also sell the tach that inputs into it? I looked on the site a while ago when the new one with the tach and all was coming out, but didnt see anything. For starters, the banshee boxes we currently sell do not have a tach output on them. There was a bit of confusion about what features were available on which ignition, so a while back I made a table of features available by model, and put it on the website here: http://www.dynaonline.com/english/atv_fs.htm The tach outputs on our other ignitions were designed to drive a standard tach. We don't sell tachs for these. The reason is simple economics. Everyone has different ideas on what they want a tach to look like/do, and we would probably have to make a dozen different designs to make everyone happy, and only wind up selling a couple of each. So we made it a fairly standard tach signal, and allow the user to pick and choose whatever aftermarket or OEM tach you want. The tach signals are a 0-12V square wave, 2 pulses per engine revolution, which is the same as most 4 cylinder sportbike tachs. If you want to do it cheaply, that gives you the option of using a junkyard tach. We have tested a tach output on the banshee box, and hopefully a production version with the tach output will reach the shelves early next year. Brad Quote

With the programming kit, you can program it to advance/retard the timing from stock however you like. It can take the place of an adjustable stator plate. It has 4 curves, all of which are fully programmable. The 4 curves that come with the box, are also included in the software, so that you can use them as a baseline for making your own curves. And yes, you can program the advance/retard to vary with RPM, so that you can do what you are describing, or even more. Here is a picture of our programming software for a 2000 RM250, the banshee software is very similar: http://www.dynaonline.com/images/dfspk1.jpg To adjust the curves, you just go to the boxes to the right, type in an RPM, and the desired timing. It's pretty simple to use. Brad Quote
