I think i already know the answer to this but here it goes. Have 2006 dyna EFI with SERT installed. it seems to idle a bit to high for my liking. can the idle only be adjusted by retuning the SERT? is this not a home fix?

thanks dogcop

 

I think you know the anwser! Ride it! If you get hot, ride faster.

 

hahahahahaha. I will.

 

I believe on SERT idle can be set. Do you have the sert software installed on your laptop, the dongle that came with it and the cables to hook it up? Do you also have a copy of the map that is on your bike now?

If yes then I am failry certian this can be adjusted at home. Your system is close to mine so, you should be able to open the file that was uploaded to your bike and adjust the RPM then reflash your ECM. I will recommend you keep the RPM above 900 and idealy at 950 or higher for good oil presure.

i did not think of the oil pressure issue. i am running about 1000 right now. best just to leave it i guess.

thanks

 

Nothing wrong with 1,000, it's where the Moco sets it.

 

I've an '06 EFI bike as well and also would like to lower the idle RPM. Unfortunately, I don't have the means (SERT or other EFM) to change it right now. If you've read the many discussions on this topic you'll hear two main objections to doing so:

1. Low oil pressure will starve the top end of oil. Reasonable argument but the '06 models were available as either carb or EFI. I do not believe that the MoCo had two different oil pumps they used depending on the intake setup. So I would think that you could set the idle as low as the carb spec and be OK.
2. Not enough rpm to keep the voltage up for the electronics. This one I don't understand at all. You've got 0 rpm when you start and your battery supplies enough voltage to operate the electronics to get you started. So assume the worst case that the rpm is so low it's draining the battery. Well it's no worse than just turning the ignition on without starting, correct. Sure after maybe 10-20 minutes you would drain the battery enough that you couldn't start the scoot but who typically sits and idles that long.

Finally if you're really worried about it just sit there and blip the throttle a few times, sounds great and should keep things flowing.
Now I'm not an expert on these engines by any stretch of the imagination so I'm still looking for a definitive answer on the subject.

 

Ya, mines set to ~980 and I didn't touch what the MAP came with. Don't care to lower it unless I was to get some kind of gain from doing that, either in Heat managment or engine life. From what I gather doing this would most likely be the opposite of a gain.

 

I'm running 900 rpm at idle. And both me and my bike are satisfied with that. I haven't had any issues with the voltage or the oilpressure.

 

An EFI motor will never idle down to potato, potato, potato, like a carb motor will. Besides the idea is to go like hell not stop and idle.
