Ignition curves

[cbn70]

Does anyone have a link to or know what the stock banshee ignition curve looks like. What about some modified curves, I am thinking of getting a dyna programable ignition and wanted a few curves to try out and see what works the best. Just for reference my banshee has plus 4 ignition on it now, stock port cylinders, fmf gnarly pipes, 28 pwk carbs, boysen reeds, case porting, and cylinder head has been cut for more compression.

you have lots more to do before worrying about crazy ignition curves.

keep your stock ignition. Dont need all that shit for your setup

Pretty much summed up by the other two poster's.

Interesting, I just had my 250r on the dyno and there were nice gains to be had with the programable ignition. So I thought another trip to the dyno with the banshee and test it out with the programable dyna.

I'm not vouching for this stock curve being right, it's similar to what dyna calls the stock curve. The Dyna has 13 degrees @ 10,000 rpm & flat lines that to 17,100 rpm.

We use the programable Dyna & it works great for us. We use it as a tuning tool in making compromises in our set-up to get the lowest ET we can for the set conditions.

 

As for our dyno tune, that set-up doesn't result in our quickest ET or MPH.
