Fuel consumption question

shellshox · Post by **shellshox** » Mon May 31, 2010 1:45 pm

Am driving a 93 esi, my fuel consumption has been low even after servicing, any idea why and how to improve it? I switch gear ard every 3k rpm, should i be pushing it more before switching, will it help?

How low is your low?
Best way is to take more highway and let it cruise..

i dont think u should be pushing the rev meter higher before changing...it might even worsen your fuel consumption..

few tips u can try..

1. try accelerating lightly...
2. get rid of all the rubbish in your car which you dont need
3. check your tyre pressure regularly.

ok, will keep that in mind, there's practically nothing heavy in the car, besides me, and my tyre pressures are just right...... Hmmm, anyone else have any clue?

What do you mean "apiggy back"?

stuff like vafc 2 , unchip , EMU and Etc............
all this allow tuner to tune you AF ratio and ignition timing hence better FC and POWER .

I thot that's what the stock ECU is suppose to do? Or is this an additional thing you have to fix on?

Its additonal. Did u mod ur car alot that the ECU cant read properly resulting in A/F ratio haywire.
Check ur tyre pressure 1st.

Car not modded, just old, so have been replacing parts as I go along... Latest change is to a stock ECU as my previous one got corroded and engine light kept staying on. Does the mech need to retune my car or something? Or is it some other parts problem? Don't really want to keep changing parts and not solving the problem...

Some ECU have been rechip before fuel map have been alter this will affect your FC.

do you have to top up coolant every now and then or does your exhuast emit white smoke when u rev hard? and is ur car somehow slower than an equivalent car for no reason?

I do have to top up the radiator water every other month but speed wise, there's still power and speed in the mid range. Will any workshop have the equipment to rechip or I have to go specific ones? Have been going to CL for awhile...

Nice car BTW....
