10 MPG Outback

[nicolo69]

Vac test was done long ago but can try again and give some results.

Load readings maybe tomorrow on my way back home.

Wheel aligment done

Better fuel done, no difference.

Knock sensor checked monts ago if I dissconected I get a check ligth.

PCV new, clean TB, IAC, EGR all tested and working acording to the FSM

Visibly inspected cats, all clean, backpressure test done all ok no more than a 1 PSI at high revs, leak at junction on pipes, none.

I wil keep you posted on new data and test.

My scanner does not have MPG calculator

I know the more data you have the better, thanks for you patience

Thats typical Japanese 4 cyl cruise conrol calibration. If you are in a lot of rolling hills use Drive 3, it will really make the car much happier.You just shut it off and drive uphill, it is not a bug as much as a silly design feature.

 

 

OFF TOPIC:

 

nipper, did you see this thread?

 

"Power mode" for 95-99 4EAT TCU's

 

i thought this might eliminate the need for the ''driving in 3'' in the hills.

 

i also wondered if having it on a timer so it came on with the car an stayed on for 15 minutes would improve the performance of the car, but avoid possible bad gas mileage.

 

of coarse an on/off switch would be good too.

A cracked knock sensor may not throw a code. Physically inspect it.

 

I would prefer to use the thing sticking out of the flor to do the same thing

 

I do that lots as it is, and will drive the car manually on occasion.

Thank you all for the advice, Ross you were right I was wrong, the LM-1 does have the ability to simulate the O2 I check the manual a was there how to wire it.

So yesterday put the sec O2 back in place remove the primary O2 and put the wideband.

The car star feeling different and the A/F look more dynamic. The trims on the scanner are on a different range. I can feel the car needs less throttle to run the same speed.

Check only the 30 mph load and was around 11.35 %.

Maybe the behave of the car are the conjunction of things (age, tires too big, ************hi mexican gas).

I am gonna keep trying different thing. First, after reading the LM-1 manual I can change the voltage output on the O2 meaning I can trick the ECU to see a more rich mixture and pull some gas.

I wil keep you posted
