Good one bro

 

Is there a specific SAFC you need to buy or are they universal?

 

maybe if you drive like a grandma- but hell, even then your ECU is doing all the work keeping your AFR at 14.7 so why bother with the extra hardware? I mean, the point is to save money, right? Even with toys like that I'm only getting 26-ish MPG (AFR at 12.8 at open loop- any higher and it's too dangerous). Stock AFR at open loop, for reference is 11-ish.

And why do people post asking for advice on saving gas? They don't want to use the REAL advice: drive less/ cut out as many under 5 mile trips as you can, share a ride with someone else, use the gas pedal less when you do drive.


there's no magic bullet that will allow you to drive like you're on the track and still get MPG comparable to an early 80's civic (47MPG per the EPA) or a hybird

It's all about the racer's creedo: pay to play.

 

indeed. hey i didnt kno u could add power with a widband and safc and save gas... thats amazing.. i would do that but honestly im the biggest engine newb on the planet.

 

here are some good tips and tricks to getting good MPG

get the TURBONATOR!!!! over 30 HP plus 30 MPG MORE! lol. just kidding. drive granny style

 

Hrm.. well, stock I was getting about 30/33 or so if I remember correctly. It wasn't stock for very long lol.

But now, after my RRM Header, RRM Test Pipe, Magnaflow Catback, and Injen SRI, I'm getting 33/42 solid. (thats in miles per gallon city/highway) I think if I got a SAFC and a tune, it would help even more. Maybe if gas prices go up more around Christmas, I'll ask for one. But, other than that, change oil regularly, keep a CLEAN air filter, and shift at low rpms.

 

You can't, really, that's my point. When you drive like you're trying to save gas, your AFR fluctuates to approximately 14.7- perfect mix for cleanest burn. You won't be albe to do any better. Adding fuel management will lean out the WOT areas, but you'll still be gettign way worse MPG than if you just drove at a reasonable rate.

Oh, my 26MPG is mostly city. On longer trips I'll see 29-30.

 

I checked earlier this week and I was getting 29mpg which is a mix of highway, city, interstate driving.. What sucks is I only drive where I have to and I'm still driving 90 miles a day... work and class only.

 

I got one of those 30 dollar gas additives thats suppose to clean you car for a year. It seriously gave me an extra 50km's per tank(this was after 35k)

 

sorry plz forgive me im a newb to engine **** and a/f ratio... so how did the other guy get better gas mieledge and more power? im confused!

 

Tornado

 

get a turbo and a whole bunch of fuel management upgrades and then run it at the track. Right after take all of it off and then WAMO awesome gas mileage.

 

He just opened up the intake and ehxaust sides. Making the engine more efficient will give you better MPG, but adding a bunch of electroincs, plus tuning time, plus all the doohickies to monitor whats going on is going to cost this guy a lot more than paying an exta 35cents a gallon for gas. If you take the retail value of all the tools I use to monitor and tune my engine you're looking at more than $1500 and I'm still not quite done

 

and 29MPG isn't that far off of the EPAs MPG ratings (which are known to be skewed high by at least 3 or 4 MPG). My advice is get one of the fuel system cleaners and switch to a decent brand of gas: Shell, 76, Chevron.
