better fuel milage

[harleyburns]

I've just purchased a 1996 escort lx ,1.9 engine I was very surprised and disappointed that it got only 22 -25 mpg.This car has 106000 miles and runs great .no oil use and nice power .anywho

First--I put three 100,000 ohm resistors in series to replace my intake air temperature sensor .the computer thinks its 20 degrees outside .this advances timing and would increase fuel except I lowered fuel psi in step two

second --I placed a small vacuum canister with a check valve to the fuel pressure regulator ,so the pressure would decrease ,so less fuel when the injectors fire
third ---I placed a voltage tap to a {volt meter} so I could keep an eye on the oxygen sensor ,I placed a dimmer switch in the in the oxygen sensor (brown wire so I could trick the computer into thinking the fuel mixture was too rich.
I'm getting almost 40 mpg Don't think this is a joke .I need some help to get to 60 mpg .

I think you would have beter luck with tricking the maf sensor with a similar set up.

tell me more

I don't know how to trick this one yet .
if it were a mapp I could do it .

[harleyburns]

Do you know how to change the timing where it would at least spark knock a little .
I've been working with water injection on this car also.
