Silly question maybe...

I've been working on my car alot lately learning as I go, making improvements.

I recently read a tech article for idle relearning procedure...

With every time I unplug the battery (reset the EEC), do I need to follow this procedure?

with a re-learn, whenever you disconnect the battery and the computer resets, you should give it a good 10 minutes at idle to get its baseline...
Then you can drive it moderatley.. its always good to give it "real time data" before you romp on it..

WOW!!! GOOD POST!!!!!!!

i had no idea about that

maybe thats why mine has been idleing like a pro-stocker since ive done my mods

ive just been hooking up the battery and going to smoke the tires right away

ive been romping on it right away

Glad it could help!!!

Below is the article I read, found on www.promustangs.com:

How to set the base idle

Answer these questions. Does your idle surge? Does your engine idle too high? Does your engine idle too low? Does your idle keep going up and down? Well if you answered yes to any of them then you might need to know something....How to set your base idle.
Note: If you do experience any of the above you will want to try cleaning both your idle motor, and throttle body and you'll want to set your TPS voltage

Disconnect the battery's negative terminal to reset/clear the computer's memory. Leave it disconnected for 30 minutes.
Disconnect the plug going to your idle motor which is located on the front of your throttle body.
Reconnect your battery's negative terminal.
Start the engine, and set the idle to the rpm you want with the stop screw on the bottom of the throttle body. (arrow)
Turn off the engine.
Reconnect the plug on the idle motor.
Make sure all accesories (radio, blower motor, a/c, lights, etc) are off and start the engine.
Let engine run for two minutes.
Turn engine off and wait two minutes then restart engine and let idle for two minutes with all accesories on.
If everything was done properly the EEC-IV (read: computer) should have learned it's new idle.

However, we all know from AFM's Tech section that we do not have to wait 30 minutes for the EEC reset: http://www.allfordmustangs.com/forum...4&postid=10736

[afarkas]

you should give it a good 10 minutes at idle to get its baseline...

It will get it's 10 minutes at idle eventually .

So, is it imperative that the idle relearning procedure be done immediately after battery reconnect or will the EEC learn it eventually?

If I repeatedly just plug in the battery and go w/o minding any EEC procedures, what bad will that do?

Are there any other important EEC procedures for the newbie?

Thanks,
Adam

Does this apply to 94 and newer also? I've heard that only the pre-94 computers have the ability to "learn". For instance. A friend of mine that has a 10 second fox body (does all the work himself) told me that he took a computer out of a 93 and put it in a 94 and it made one hell of a difference. He said that was because that in 94 the computers no longer had the ability to "learn" after mods were added. Anyone else heard of this?

BTW if this does work (idle setting procedure) I need to do it. My car surges pretty bad, especially at initial startup. Not as bad though since I upgraded to my 24# injectors.

Just updated profile to include mods. Sorry for the test post.
