You can also pull fuse #47 for 20 minutes for the same effect.

 

Thanx! Another tidbit saved to file...

 

Its called Keep Alive Memory ... it takes a dealer less than 5 minutes to clear it with IDS software ... It also gets cleared when you load a custom tune with a tuner .. or when dealer loads a new calibration in the PCM.

 

Does simply disconnecting the battery for awhile accomplish this like it clears 'learned' driving?

 

From another Forum:

The KAM can be reset using a capable scan tool in a few seconds. If you don't have a capable scan tool disconnecting the PCM (computer) for 10 seconds will also work. Another method is to remove the positive battery cable and connect a jumper to the positive battery cable end to ground for 10 seconds.
If you leave the battery disconnected for a long enough period it will reset the KAM provided the back-up power supply is discharged. The backup power supply is mainly used for the air bags, but it will feed other modules for a period of time also.
It should also be noted that anytime you load a new tune into the PCM the KAM is reset also.
It normally takes about 50 to 100 miles for the PCM's adaptive strategy to relearn. When you 1st start the car after resetting the KAM you should let it idle a couple minutes with everything turned of in park/neutral. Then turn the a/c on for a few mins, and after that put the vehicle in gear for a few mins if you've got an auto trans. When your done relearning the idle strategy, drive the vehicle like you normally would. I do not recommend driving it in a manner out of the ordinary at this time.

 

This is what I have for idle re-learn:


Theidle learning process is simple. From a cold start, load your tune - or in this case since you're not running a tune for the cams (which I recommend you do) just unplug the battery overnight -
then from a cold start, with either the fresh tune or the battery cable back on after a night without it, let the car start and idle for 8 minutes without touching the throttle at all. Now put the A/C on for 2 minutes, still at idle without touching the throttle at all and without shutting of the car. Now after 10 minutes of idling (8 without AC and 2 with AC), you can drive the car for approximately 10 miles... make sure it's not just highway, but stop signs, traffic lights, etc. You will have completed the idle learning process.

 

Which tune do you have? Mine is tuned but still isnt as responsive at least the 87 street tune

That big a difference? Which tune?

How do you get the throttle delay removed on a tune?

Its 20min? I pulled it once but only for about 10min..

You can do this with a tuner also even without loading a tune. The sct tuner has a kam reset option i. The special functions section

Sooo officially to do the idle re-learn its 10min idling with the last 2 with the A/c on? Then driving a combo of city and street?

Is there any negative to not doing this? Whe. I last reset by pulling the fuse i didnt do the idle relearn, wasnt aware of it

 

I don't have any throttle delay with my $200 Evolution (Lund) Performance tune and my $75 MPT tunes.

I don't know if other tunners remove the throttle delay or not

 

MPT and Hybrid Bama tune!

 

It's been pretty wet for the last couple of days, so I haven't been able to do much spirited driving to check it out. However, from what I have been able to do I have concluded that the car IS much more responsive than before. It may be nothing like what a good tune would do for me, but this was all Ford's doing so I have no risk. We'll see what it is like the next time I run autocross with her.
