Okay who has one and have you had to rejet after you installed it? Or Calibrate as they say. I tried it and it will idle just fine but spits and sputters as I give it gas. This is in the stock setting. I have checked and rechecked and all looks right. All that is left is to calibrate it like the instructions say, but if it is in stock setting shouldn't it be fine. I don't want to start rejetting if something else is wrong.

 

I didnt have to rejet and also I installed one on my stock Raptor and it even runs fine. Try the 3rd setting and see what that does? Yours maybe defective.....

 

I ru one but i run customs curves and it is fine, but you have to program yourself to get the extra RPM...

 

I'm going to try it on my stock raptor. But why does it have the calibration section it must happen some times? The other bad thing is I bought it off someone and I'll have to battle with them if it is defective. Why Power curve 3, I notice it drops off at the top?

 

How old is it? Maybe they still have it under warranty?? I like power curve 3 because its the most agressive one.

 

Where did you read about the calibration? I have that but its on my laptop but didnt see anything about it just being the CDI?

 

He had it for about a month. I'm in the process of chating with him. I have spent allot of time getting it dialed in with the modded carbs. But just maybe if I was running close to lean this pushed leaner??? Plug is tan with no real black at all.

 

It is in the instructions but it is talking about having to rejet in some cases. It says to put it on stock setting that is the closes to stock. Hmm I may be reading it wrong. I really do prefure pictures.

 

I just thought of something that I need to find out if it is an 01 Dyna FS I have an 02 Raptor. [img]i/expressions/face-icon-small-blush.gif[/img]

 

that is very important, it wont work unless it's for your year...
