well when i got my fc on the road the fuel miledge waz approx 8mpg.. after reading the fsm for a night and fixing my vac leak i started my attempts to get the fuel miles better what i did waz

Adjust timing
Adjust TPS
Test AFM to make shure its in spec
installed a Cat
installed a air pump that runs directly to the cat
fixed ALL vac leaks
new o2 sensor
adjusted that lean rich idle adjuster thnig

i did all that, then went to the fuel and calcated the fuel miles and got 15mpg city
now since im on my permit and i cant drive without anyone, i do alot of driving in the driveway and idling, so i figure if i dident do that i would prob be in the 17-18 mpg range??? but i figured ide pass it around mabe it can help somone else get there fuel miledge up becasue i know how much 8mpg sucks


peacee

p.s approx 300 miles on rebuild running STRONGGGG

 

I get 9 mpg...I think it may be the o2 sensor, but I can't justify paying over $200 for it. (Mazda Trix)

-And hopefully with my standalone the o2 sensor won't do ****.

 

that's odd, I think I paid 20 bucks for my O2 sensor at napa.

 

mine came with a parts car, sitting in the back brandnew in the box, i think there NOOO more than 40 maxx

 

O2 sensor doesn't make much of a difference IMO. I've had mine fried and unhooked for about 3 or 4 months now and I still get 18mpg full city driving.

 

i get like 9 MPG and im 20K on rebuild

 

I'm actually surprised that those changes would result in an improvement for a car getting 8mpg. 9mpg is also bad. That's not normal, you need to look into that.

 

Well he has a huge *** vac leak, car ran all messed up, his gas gauge was fubared, and the 8/9mpg was his "guess" never really an exact calculation

 

Once you drive it more, and start learning the car better and it's powerband, as long as you don't baby it and drive like a sissy it should go up quite a bit.

 

lol.. 200 for an o2 sensor??.. its 17.99 at autozone.

 

wow...haha go check mazdatrix.. that **** is crazy.

 

i dont know what my MPG is just that its seemed to go down since i started premixing

 

Yeah, the 02 doesnt really do anything untill its in closed loop (freeway or cruise driving) It just gives your computer a bit better idea of where your a/f range is at when you locked at a certain speed/throttle load. I installed a new one before my long *** trip to north idaho a few months ago just to get the extra edge on gas mileage ($20 bucks or something at napa). The last drive up there i managed to get 27-28 MPG, I think the open intake and fairly open exhaust help those numbers too. Also keeping all your sensors in spec helps that mileage a bunch too.

 

how old do you have to be to get your license over there?
