This maybe common knowledge here but it's a mechanic trick.
Take your ecu fuse out, tap the brakes (drains the residual power in the computer) re install the fuse.

Basically that reset you ecu/ecm or whatever you want to call it.
now the motor will reset a few things take some fresh reading as far as air temp and desity, and relearn your driving habits etc. there's more to it but that's the jist of it.

my wife is a fast driver who gets 13mpg in her DC tundra, after I do this every six months or so I can get it back up to and keep it at aprx 16-17

Please use the search, link.
Use the Search feature for what? He wasn't asking a question. Dieselguy was just trying to pass on some information for the benefit of the rest of us. I've never heard of this before and I appreciate him sharing this information. Any other mechanics out there that can confirm this will work?
that post is funny! It has me rolling around laughing or whatever internet term that is.

Take a legit action to help with mileage and that guy has everyone making fun of him! What a bunch of idiots! oh yeah in does work.
some of you need to put a group buy together for the tornado, or KN airfilters, or fram oil filters! :rolleyes:
twincam, thanks for the good reply

So I should make new post that I got my brake TSB done for my Tundra when there are over 50 post stating the same thing, or one that says I just got my ball joint replacement TSB. I am not trying to "diss" Dieselguy, I am offering a suggestion that he use the search function. I have used it to great success.

I do appreciate your suggestion, however...it has been mentioned before and it does work, as long as you remember to do it every few months. As for the KN filters and Frams please do a search, there are some really good topics on these products.
There is only one way to permentley get more milage from any stock vehicle. Being able to adjust the computer on the fly. There are products out there for Ford, Chevy and Dodge to adjust the computer for towing or just highway milage. They can be adjusted while driving. As far as I know there is no such product available for a Toyota. Toyota made their computers not very user friendly for the average driver.

At one time they did! I had an 84 Toyota Camry that had built in buttons to adjust the timing for Power, Normal, and Economy driving. Never seen it since.

Then you do the hokey-pokey and you turn yourself around!
Hey, that's what it's all about!:D
I only know this works when installing an aftermarket C.A.I.
BTW, if your C.A.I. didn't work for you, you most likely skipped this step.;)
I'm glad diesel guy is laughing. Everyone should have entertainment. I believe that mostsleek was merely bringing up the point that there are dozens of threads about this topic including a recent one about disconnecting the battery. Give this a try: drive normally and get 17-19 all around. I too laugh at some of the posts because they're dumb. As he says, "what a bunch of idiots". Well I have seen a bunch of idiots mess with computers on a variety of things, cars included, and eventually they "smartly" broke their toys. On this site it appears that many people fancy themselves as engineers, or they really believe the websites they find with all kinds of information about synthetic oil etc. This post is just another of the many extraneous posts that should be filed away. And yes I made an extraneous post the other day, but I wasn't repeating 49 other posts infromation, I was asking a question and got a lot of helpful information.

Thank you for sharing, dieselguy. Don't mind the "new thread" police - they're just doing their job :clown:
wheres the ecu fuse?
Just disconnect the battery for ~15min.

i thought stickers helped mpg?
i thought stickers helped mpg?
No, no, no. Stickers/vinyl adds horsepower :rolleyes:.
OH...i see...so, if i put stickers on my intake, that should help me get more mpg!! hahaha.:rolleyes:
ive heard that pounding an oversized potato into your exhaust pipe will help your fuel economy too. but im leaving that up to someone else to try....lol...any way i have been impressed with my 5.7s fuel economy ever since the get go, but recently put on a full set of cooper discoverer at3s and am having areal hard time reaching past mpg. even on the highway it is much more difficult to achieve the averages on my dashboard instruments than i achieved in the past. love the tires road gripping abilities and low noise, but feel that i have sacraficed some mpg until these wear out

One thing to remember is all tires with more tread on them (new) have greater rolling resistance and will lower fuel economy.
