can you share the info for on the tuner chip
thanks
OK, This is what the mechanic told me. I don't really know what it means, but this is all there is:
It is the
Dyna 3000 module. He set the
rev limiter at 5000
rpm (after I told them I was interested in reliability) and then 3 degrees of retard and 6 degree advance. He said the pounds per square foot of compression went from under 100
psi (stock) to 160 psi with the Yamaha high compression pistons. That's all I know. Hope it means something to you.
I have stock intake and exhaust is only the stage 1 mod.
It runs like a striped-assed ape now, and you can feel the new level of compression in your nards. It doesn't run out of breath and pulls like a tractor. Haven't hit the limiter yet (still in break in mode).
It is a lot louder, and other guys hanging around the bike shop stare.
He told me he could make it a lot stronger by revising the breathing through less restrictive intake and exhaust, which would, in turn, justify another cam. I said "no thanks" as I am currently happy just the way it is. He also said that would make at A LOT LOUDER, which I clearly don't need or want.
I guess I might have done this backasswards, as most people do the pistons at the end, after improving the breathing. But the way it is set up, it runs beautifully and sounds fantastic. I guess if I get board, the easier stuff is all that is left (except for a cam).
Hope this helps.
