Best mods to increase gas mileage

[lemmez]

so i've had my set up for about 3 days now. E/H/I and my average mpg used to be 25mpg on a 2az-fe (i like to take off fast). I've actually been driving more agressive than normal and right now my mpg has actually gone up to 30mpg!. On the gen 2 that first cat that i took off really made my mpg crap. The owner at jpp performace, jose, told me when i went down there that in our solaras they really make that bend sharp from the header to the exhaust and the cat really slows ur car down and restricts a lot of air flow (sorry for the run on sentence, im tired). I thought he was just throwing me a sales pitch but he was actually right.

wow thats really bad. I live in long beach and go to hunting beach all the time and fight traffic on the way home and still get 30mpg now since my upgrades. Headers ftw!

On my Gen 1.5 1mz-fe, I got an average of 19mpg on mixed driving. However, I put in a K&N air filter and my economy went up quite a bit. Granted, it was all highway driving but this past weekend going from Melbourne to West Palm Beach and back I was getting 26mpg, above the EPA average.

I'm going back to my regular daily driving routine this week and see how it helps the mileage, but I know for a fact that I usually got 22mpg on the highways so it's a good start.

240 miles on half a tank (18.5 gal / 2) = just below 26mpg

When my tunes stays in I get much better mileage - but when something triggers it to fail and throw CELs, then it drops like mad.

I picked up my ride on Friday (had Split Second re-tune before it went into Lanzini's shop) and it was running great - no CELs or anything. Drove it home from Long Beach to Ojai and then all over Ojai to Ventura & Santa Barbara this weekend - lots of slow curvy roads - ave 26mpg. I usually get about 20-22 when the tune is out - but there's still something screwed up electronically and the tune will go out in a couple days.

I'm really hating this flippin drive-by-wire over-ECU'd POS though... I'm seriously thinking about returning it back to stock and trading it in on a Prius.

Or get a 2az-fe solara . who tunes ur afc? and how much do they charge?

I went to split second they are charging me 100$ for street tune, 175$ for dyno tune, and 75$ to instal afc. Can anyone help me install my afc when i get it?? i would be for ever greatful.

I drive an auto 02 SEI4. I’m running on all stock and I got 375 miles on 18 gallons of 89 octane. (getting 91 octane after headers, new spark plugs, intake, and exhaust.) I’m like 15% passive and 85% need for speed. Half highway, half city.

375 miles/18 gallons = 20.83mpg. That’s not that bad comparing to my 96 maxima v6. I drove the same way on it and I get like 14mpg. HAHAHA!!

Let’s just see how much mpg I gain after the upgrades.

Good night. It’s 2:44am where I’m at and I gotta get up at 6am for class.

W/SC, manual, bigger injectors, bigger fuel pump, K&N, & catback exhaust... I'm getting an average of 24.5mpg. I don't smash it or drive her hard since I'm not tuned right. I do about 95% highway driving and living in Iowa... we really don't get many traffic jams.

It's not hard to do. If you've installed a deck before, you should be able to do it. There's afew write ups and a tutorial(I dunno if the gen2 ecu is the same as the gen1) and follow the manual too.

However if you still don't feel like it's in your talents. I would have it done by someone who has done it before. You really don't want to hurt something.
The one thing I did different is I didn't use the male/female connections they supplied. I went and bought butt(hehe I said butt) connectors.

Split Second made a special box for me - tuned for the JPP headers. I had a dyno tune first and it was weak - went for the street tuning and it was much more aggressive/responsive for about a week. Now its back to crap. They claim its a bad sensor or something... gotta check out the CELs I'm getting to see what it tells me now. No body wants to claim responsibility it seems!
