And I agree, it does sound totally bogus. Comparing it with the car was a good example. But seriously, it works. What do you want, and hour long video of me filling up, driving down the highway, and filling up again for proof?

What do you think a discussion is? Its people arguing.
Im not into arguing either, and i geuss theres no need to discuss it further.
I have a real hard time seeing how its possible, doesnt mean its not. Just saying, its pretty hard to believe a motor would get better mpg in a heavier vehicle for no reseon. And why wouldnt toyota just do this to win the mpg wars?

Really not tryin to insult anyone here, but I wouldnt expect you to believe me if I was claiming this.

nothingbetter

If/when a mod reads this can you delete our bickering? I feel bad for stealing a thread for such stuff.

ThatGuy1295

Yup wouldnt want anyone to know you got called out, and couldnt even give one reseon for why your claiming what you are.

You should feel bad, tryin to pull a fast one on the honest members of yota tech.

Did you lean out the motor with the safc? What's your a/f ratio at? Leaning out too much with a piggy back is dangerous cuz the stock ecu advances timing as it thinks you're at lower load and lower rpm. Only time I've gotten 30mpg was going downhill. But that doesn't tell the whole story cuz you either went uphill to get there or you have yo go uphill to get home

nothingbetter

I'm using the factory fuel curve in low throttle. I've adjusted the high to remove fuel under boost so it stays around 12:1 under heavy load. Without removing any fuel from the factory map under load its stupid rich.

Wow. Really? What do I have to do to prove to you that I can get such fuel economy? Video of me filling up, driving, then filling up again while recording the distance with a gps, doing the math and posting it?

If you post 30mpg in a car enthusiast community or a scientific community you will get the same scrutiny. It's just the nature of or world that we don't readily accept outrageous claims without evidence

nothingbetter

Toy, you've been decent about this, which is great. But "thatguy" has insulted me with his comments and I will not be called a liar. Video has been taken of my drive. Silly me recorded it in 1080p so it will take about 3 hours to load to my puter. I can then lower the quality, let it load onto photo bucket overnight (hopefully they let me load something so big) Then I'll post a link to my PB account and you can watch all wonderful 50 minuites of me filling up, driving and filling up again. In case you don't want to wait that long or refuse to believe me I drove 35.3 miles, used 1.475 gallons of fuel. That ads up to 23.93mpg according to my calculator. Apparently I just outsmarted 30 japs with unlimited funding.



Please tell me Thatguy...so who was lying again? I havn't mislead anyone. Vids will come to prove it. And when can I expect these phone calls from Ford, Dodge, Nissan, Toyota, and Honda all trying to sue me? I'm not trying to pull a fast one on anyone, but if you want to have a drag race, my toyota trail rig vs yours as they sit now, I'm up for it. Better start tuning, my 0-60 time is just under 7 seconds. (vid of that is already on here in the 0-60 thread since I'm sure you'll want to see that for proof, but you'll probally still doubt it anyways) And just to top it all off, you're living in a first world country with an endless amount of knowledge and education available to you...the least you could do is learn how to spell, use some half decent grammer, and figure out the denotation of "motor". You should be getting mind blowing fuel economy with a motor under the hood of your truck, seeing as how motors don't use fuel...they use electricity. I happen to have an engine in mine, which is why I burn fuel.

ThatGuy1295

I know its fast. I never doubted that.

My argument is puerilely scientific. You dont know why your getting great mpg. DO YOU?

General speaking HP usually sacrifices MPG. So atleast give us a reseon to believe you. Until then Ill wait to see your video. And I will watch because I want to believe you, but cant until I have a thread of evidence to do so.

PS what are you talking aboot? Motor. Thats what I said motor.
So theres motors and motors, you dont make any sense,, why dont you learn how to argue and ill learn how to do what im doing,, deal?

ThatGuy1295

And if your going to the trouble to prove it, which I think is great. Then you wont mind posting a short vid of your speedo compared to a gps, just to prove your speedo isnt way off.

ThatGuy1295

And thats how I found out your full of it

And PS i dont have to be good at spelling to know an idiot when I hear one.

nothingbetter

I used the mileage and speed off of the gps, not the odometer as I know its not accurate due to the tires and re-gear. The gps said it was accurate to 3 meters. Should be close enough.

Ah yes. Factory toyota turbo ecu im guessing you were running a 10:1 a/f under full boost LOL. I wouldnt be surprised if you've seen 9:1 in high boost situations. Just be careful with the AFC. your riding on a fine line. Heavy Load, High Boost, Pump gas, and ADVANCED TIMING don't mix good.


Generally speaking i would say you are right. However, the 7mgte is a turbo engine. hence the toyota designation "gte" Turbos were actually designed for increased engine efficiency.

In my 3sgte mr2 I dynoed at 300whp @ 18 psi of boost but consistently saw 25mpg on the freeway. Although it only weighed 2860lbs with me in it so we are comparing apples to grape fruits... the point I am trying to make is with a turbo engine, as long as you are not boosting max and not cruising in redline you can get great gas mileage but still have the higher HP on reserve.

Next point ...
Curb weight of a mkIII supra comes in at about 3600 lbs ("nothingbetter" weighs 500lbs more) and people with the mkIII supra consistently report 20-25 MPG. This info isn't some miraculous crap I pulled out of my ass. If you really want, go to the supra forums and read...

He didnt report he got 30mpg consistently... he said it was his record... so he was probably going down hill. with all this info said... here is the list of relevant info in a table format...


89 Supra:.................................................. ................. Pickup:
weight:.......3700lbs................... >> +400lbs >> ...........weight:... 4100lbs

Tires:........ 18" ( +or- 2" ) ........ >> +17" >> .................tires:...... 35"

ECU: .........STOCK ................... >> Leaner a/f >> ..........ECU: stock +SAFC
Body:........ :jessica: ..................... >>Rectangle>> ............Body:....
MPG: ......... 20-25.................... >> same? >> ................MPG: 20-25

soo.. the only thing that could give "nothingbetter" equal MPG to a MKIII supra is if he leaned out his a/f ratio enough that it was borderline dangerous but perhaps still working... or... perhaps he drives like my grandmother...? You guys were both starting to sound like politicians... arguing about each other's grammar and all this irrelevant info?

oh you didn't know supras were heavy fat ass cars?

I wish I could swap a 3sgte into my 4runner because Im very familiar with the engine...
but the 3sgte never came RWD so its just not a smart idea as there are plenty of other options out there.

woooooow this thread turned into an argument real fast. such maturity shown here.

racerflea

Um guys i think u might want to start taking engine load and egine speed into consideration speed wecan easily measure (rpm) load u need a tuner to monitor OP id sugest getting a scan gauge if u have the obdII hooked up

racerflea

But if u like cruzing at 65 id go with the 4.50s so ur at 60 around 2k i think that would yeld ur best power and mileage

ThatGuy1295

Pick a side or SHUTUP



Wiki says 3400 pounds for the supra, and his trucks probably around 4500. As most sas'd rigs around that year were about that. I wouldnt be suprised if there was a 1000 pound difference between the 2 vehicles. And a big difference in wind resistance. The supra's aerodynamic, and the truck is not.

Why would you assume that mpg could even stay the same?

ThatGuy1295

Is that a custom toyota gear ratio?

"4.56" is a big change from 4.88s. Almost seems like it would be to high, the 4.88 gear set would probably be the best of cruising and offroad for such big tires, with a 4.3 motor.


4.88's would put you at 1900rpms at 60. Thats closer to your 2000rpms then 4.56's would be. 4.56's put you at 1800rpms at 60mph With the 4L60E

ThatGuy1295

Also the 4L60E looks like it has a really tall OD. Puts you around 90mph @ 3000RPMS in OD.

Thats with 4.88 gears, and 35 inch tires. I dont think you want to be any higher geared then that. It might not even hurt to go lower to 5.29's, but I dont know if it would be worth it mpg wise.
