Post ECU Reset Question (But not "How do I?""

I put on my Stromung Dual and Midpipe today and disconnected the battery while I was doing it. Well, It only took me 15 minutes to do so I hooked up the Battery and then only let it idle for around 5 minutes.

I have heard 20 minutes disconnected and 10 minutes idle. Is that set in stone or should I be OK with 15 minutes and 5 minutes?

I don't know about the RS but the 88 would reset after a little over 5 minutes.
Also it might not truely reset, as Ford's ECU in the SHO can store data for more than a year with no power.

But yes 15min should do it if it will reset at all by that method. Can you imagine service techs sittign around for 1/2 an hour with a pissy customer breathing down thier necks about a Check engine light??

I would guess that service techs have a code pulling tool that can also reset the ECU. I know that many of the code tools can reset the specific check lights without much of a problem. I don't think they use the disconnect the battery method at the dealerships

Yeah the mechs has this Tricorder type thing with some cables that plugs to your underside steering rack.It does a whole bunch of suff with the car. Pretty nifty. The mech once showed me how to use on of those things. Yup very UnSubaru like.
