How Often Do You Reset Your ECU?

Did it today 30 minutes prior to leaving work and I've got to admit the drive home was like no other. I read the whole thread and saw people posting that its just in our heads etc etc. Take my word for it, prior to resetting the ECU I could not get the car to peel out as HARD as I tried. NOW I give a little gas and the car starts to peel out itself. The RPMs are definitly hitting higher numbers before changing gears and the car is pulling like I've never seen before. I'll be pulling out the ECU B fuse every week or so.
I prefer to do it by taking out the fuse. If I disconnect the battery I lose memory seat and tilt steering settings which I really dislike. Plus the fuse method is easier anyway instead of having to put one foot on top of the battery and yanking out the cable with both hands and a generous amount of swearing.

I was highly skeptical that this would work....BUT since I bought a used 2000 gs300 I thought I would give it a try....WOW it really does change the driving characteristic of the car...I was pleasantly surprised....In fact I nearly peeled out of my driveway in reverse...I think once it learns your driving style there should be no need to reset...unless you want to feel the full potential of the car. 
Thanks for this tip 
I decided to do option b. pull fuse....It did reset my radio and seating positions. fyi.
BTW....if you add a sticker....reset your ecu.

I pulled the 20 amp "ecu b" fuse...I didn't think it would change anything as well...but it did. Just radio and seats though...not a big deal.

I kind of did this, i had to replace my battery, and when i put in the new batt my ecu reset. and i let the car run for about 5 min then drove it for a bit and it felt better then when i got the car. Idk if it was the bat or the ecu reseting itself did anything. But there was a diffrence in thump.

I don't, the ecu doesn't learn anymore. I'm running a Map ECU with a 74mm turbo. I had tried all the tricks, installed a resistor to trick the ecu in cold start mode, hooked up a black box to reset the ecu on every ignition shut off. Then I read on the IS300 forums that a guy spoke to an engineer at Lexus and asked about ways to get around the learning issue, the engineer replied, thats easy... just unplug all 4 02 sensors and it will keep the car from learning, the ecu will only run in cold start mode. It works for me! And I have my temp gauge back.

Do i have to remove the battery cable and then pull the ECU fuse, or i just need to pull the ECU fuse for 10 mins?
For the newer members here, this is accomplished by a couple of different ways:
a.) removing the battery cable for a few minutes
b.) pulling the ECU fuse in your fuse box located (in the 4) in the engine compartment near the windshield, passenger side
I try to do it every couple of weeks. I drive my car relatively softly on a daily basis, so its nice to get that extra kick in the pants after the reset to remind me what the car is really capable of; nice to execute on a Friday when I tend to really drive it on the weekends.

That's clearing codes, not the same thing. Plus if you get CEL's and VSV's, than there is something wrong with the car.

Ok Another member to try the test.. I bought my 2nd GS, an 01 GS430, from the original owner in Oct 07. Car was pampered and garaged its whole life, and the 50ish year old owner was not one to run the pants off the car, plus figure 36k in 6 yrs, that is just 6k/ yr. So if a car can become mild mannered by easy driving, this car is it.
I noticed it is not quite as peppy or brutal as my 99 GS400 (125k) in the speed dept, I figured the trans or other feature changes made the car more 'refined'. We'll see tomorrow how she runs.
