if there is any device can manually adjust the idle speed on my 09 ultra classic? thx help

 

I believe you can adjust the idle with a Power Vision.

 

You could use the SEPST and make some limited changes depending on engine temperature. I believe you can adjust down to 800 rpm. But no lower.

 

You didn't say if it was idling too high or too low. If you don't have a tuner that can adjust it or don't want to spend the money on one, you can have a dealer do it. They won't adjust it below a certain rpm. Too low and you take a chance of dropping your oil pressure too much.

 

If i can set it to 800 rpm, that will be good enough.

 

Promise not to complain about the bottom end of your engine is shot due lack of oil pressure or your battery not staying charged if there is a lot of idling going on. I don't think you can ever make a twin cam sound like an old shovelhead. My 02 carbed 95" with cams will idle down to just under 1000 rpm and has a nice sound but I won't go lower, my wallet isn't that deep. Good luck.

 

Manually? no

Like most modern FI systems the idle is set by the ECM

Most tuner software will let you set it to some extent....

But you need to keep oil moving through it at idle to help cool it, reducing the idle is not your friend.

 

I do understand the oil pressure is the main concern, so i will only have my low rpm during start the bike or show off at traffic light.

You should be fine, as long as you don't start the bike or let it idle.
