I have not seen any maps for the dyna. Tell me what they offer. They should have one that advances 5* off bottom and then ramps up quicker to about 36* overall.

From the website

Curve #1 is a mild performance curve with a little less total timing than the high performance curve.

Curve #2 is a high performance curve with the maximum amount of advance.

Curve #3 is a timing curve that would used with high compression pistons which has less total timing than either of the two above.

Curve #4 This curve is basically the same curve that is used in the Velocity Devices unit with a slight change. This curve has been tested on our Teryx and dyno and proven to add just a little more peak HP. Number #4 has been programmed by Todd at HUNTERWORKS, if it wasn't bought from there then #4 is the original stock curve.

Don't know if this helps.

Can you not advance the timing curve yourself on the Dyna like you can with the VDI?

Sounds like #2 was what we were running on our 4 wheel quads but #4 is what we run on XChamps

Yes you can, but you need the computer software and cable hook-up to the CDI.

So, I keep it on the HW #4 curve? Is there somewhere I can see this curve?

Thanks

You can see it if you buy the programming kit.

I would use it and listen for signs of detonation.

FST,
I am wondering about these 840 kits you are selling. I know your Valentines day love deal was appreciated by those few guys. Are the cams/rocker arms and springs included? If not, are they required or just recommended? What added performance do you get from the cams/rocker arms & springs? It also sounds like I will need a new programmable CDI? I guess what I am looking for is the total cost of the parts required minus of course, any core charges? I don't want to do any valve or head work at this time. Thanks
