How do I adjust or get back this feature? I have been looking thru shop manual and can't find any reference to it. Bike will start if I give it throttle until it warms up.

 

It's all in the manual in the FI section for idle speed adjustment. There is also a post or two on this forum if you use search. Be aware that one of the methods on the forum is for the later MM and won't work with the 95-6 system. Not hard to do.

Setting Idle On MM Systems

--------------------------------------------------------------------------------


You need to make sure the throttle cables are not hanging up, are lubed properly and the throttle is closing all the way, and the throttle return spring is OK. If all this checks out:

I'm assuming you have MM EFI. If so:

1. Remove your right saddlebag and side cover.
2. Remove air cleaner assembly
3. Start the bike and make sure it is at normal operating temp.

You Need A Tach For This Part:

4. Adjust the hot idle to 950/1050 rpm.
5. Unplug the temp sensor.

Your bike now thinks it's cold!

6. Set the cold idle to 1500rpm
7. Shut the bike off.
8. Remove the 5 and 15 amp fuses from the fuse block which is on the side you took the cover off of.
9. Plug the cold sensor connector back in.
10. Replace the air cleaner assembly.
11. Wait at least 30 minutes, then replace the 2 fuses
12.Replace the side cover.
13. Replace the saddlebag.

When you restart your bike, the ECM should remember the new idle settings you did .

A different way of doing the above mentioned that I found if you have no luck with setting it...

This describes a method to set cold and hot idle speed on Magneti-Morelli EFI systems.

First, when it comes to setting cold idle, the service manual leads you down a path of frustration. This is a very simple and effective way of adjusting it. If you start the engine stone cold and it idles below 1200 rpm (after it stabilizes) then turn the cold idle screw (in linkage, on the side that rotates with the throttle plates) in. If it's over 1300 rpm, then turn the screw out (therefore, set cold idle speed at 1200 rpm for TC-88's)It's that easy . Also, to guarantee that the idle will be recognized by the ECM, run the bike until it's fully warmed up, turn the hot idle (in the throttle body, forward of the front intake, near the bottom) up to 1200 rpm, shut off the ignition and pull the 5 amp fuse (in the fuse holder on the ECM brackett), run a lead from the cold (relay) side of the 5 amp socket to ground. Let it sit for 15 minutes or longer if practical, then put the fuse back in and warm it back up, turn it back down to 1000. Works like a charm.

The Magnetti Morelli was used on baggers from 96-01 never on Softails. The Delphi is used on the Softails and all '02 and later baggers.

Before you do any adjustments, make sure you don't have any codes. If you have any codes, correct this first. Make sure the throttle cables are adjusted properly. Make sure the Idle Speed Acuator is working as well....when you turn on the ignition, this should extend/rectract. Replace now if not working. Lastly, make sure the throttle body is clean and nothing is plugged up.

I've tried the shop manual....too complicated and never really worked well for me.
I've tried the above instructions, disconnecting the temperature sending unit and removing the fuses. This way has worked, but I can get the same results or better using the below method.

1. Make sure the bike is fully warmed up......confirm the idle is around 1000. If is, then great. Otherwise, remove the aircleaner and adjust the idle screw located bottom right of the intake on the throttle body. Install aircleaner and recheck idle....

2. While engine is running, disconnect the Idle Speed Acuator above the throttle body. Adjust the cold idle screw above and just to right of the throttle body. This is where the throttle cables are on the throttle body. Adjust it to about 1400-1500. Reconnect Idle Speed Actuator and allow the idle to settle. Then shut off engine.

3. Disconnect battery and let sit.....30 minutes is plenty. Then reconnect!!

This way seems to work pretty good for me. I'm not saying this way works for everyone, but it is worth trying. You'll know that the system is working by, whenever you start the engine....the idle will raise to approx. 1300-1500 and then quickly settle to about 1000.

The adjustment screws are tiny, the head is either allen or torx. Once you find a method of adjusting that works for you....print those instructions and keep with the bike. Hope this helps...

 

Thanks, it's idleing again when cold, EvoRider, used your method. Thanks again. Beer is in the mail.
