DC2R milage problems etc!! (i.e ASK tinks)

BTW checking if your thermostat is phcked... its obvious but some people dont realise all you need is a thermometer and water in a saucepan. Heat up the water and keep an eye on the temp. When you see the valve open take a note of the temp and compare to the specs.

fark.. I have been getting at least 600km per tank

in a DC2???

well, since you gotta take it out to test it, most places wont bother testing and simply replace the thermostat if the car shows symptoms of failing thermostat...

but i guess you are referring to DIY...

in a DC2???

yupp...dc2r... stock rims, axle back, CAI, cam gears. I usually get a yellow light at 500-530 (on and off) then consistent yellow light at 550. still only equates to 6 days of before I have to fill it up =(. In my Gen 1 integra I used to get 650km off it, but I would bring that right on the red, bad I know.

in terms of the thermostat test: yeah, it would be probably be better off to change it anyway. but it just lets you know if you have been looking in the right place in finding a solution

[tinkerbell]

wow - great milage for DC2...

i got 690km from 45l on the Hume to Melbourne with a B20VTEC, but that was in (my) full economy mode (steady load/speed)...

who/how were the cam gears set? if at all?

[Rexxy]

do you get soot on your rear bar?
i get heapsss
even when not thrashing, i normaly don't rev above 4k and i still get that black crap.

hmmm, thats not a good sign, i would be pretty worried about my engine if that started to happen.....

how's your shifting?? what precise rpms do you decide to shift??
alot of highway k's?? pls tell cause i get half that. actually im on 360kms now almost to the red E bit.. but not quite there yet. and it's a tuesday so i have to fill up cheaply. also my fuel meter was half gone when i had my thermo replaced, so maybe when i refill that's when a accurate result will arise.
lets all hope.

mobil better? atm i running BP ultimate mainly.

well not getting it now that my thermo's been replaced. i've even thrashed it a few.. vtecing it and what not.. not much blacksoot.. there's still a bit.. but not as much as before.
im still going to keep an eye on it though. i dont know things just aren't going right atm. buy a new car, gets hit a week later.. rubbish. so mcuh things i need to fix up on it and no time to get it all done =@!!

no differnce, if they are 98 octane...

[fezp]

i heard united has 100 octane.. would that make much diff? 2 octane more?

[Rexxy]

shouldnt, the car is tuned to use 98o fuel (or at least at 95ron), anything higher you wouldnt see anydifference unless you have the timing changed accordingly, i think its a +1 or +2 timing to adjust it to use a higher ron. Tink or Cambo would be able to explain this in a more mechanical/scientific manner.....hehe

actually i think the car is tuned to 95ron, but 98 helps it with pinging and performance, and a timing adj or +1 or +2 tunes the car to 98ron.....so a 100ron used in a 98ron tuned car wouldnt be a bad thing...

[l3vnd1]

I used to use V-Power racing which was 100RON; but when I reearched the effects of 5% ethanol, I went back to either V-Power or synergy 98.

fezp: if your car continues to use alot of fuel you may want to get you ect (engine coolant temperature sensor) cheaked. its job is to tell the engine computre how hot the coolant is. the computre will use this and amount of air coming in to the engine to work out how much fuel to give the engine. if the ect sensor is reading to cold it will over fuel you engine. you may also what to get a tune up this includes fuel filter spark plugs and air filter.
hope this helps tried to keep it simple

[ewendc2r]

Mate I can almost definitely say its your O2 sensor -- I've had the exact problem you have encountered (except mine has gone twice .. hows that for luck).. Do an diag check.

[theHKway]

i dont know if this as been answered
but if you read your manual, you should be shifting around 2700-3000rpm at every gear
i have a VTI-R and that what it recommends, if you have a DC2R it could be different, but wouldn't be by much

have your car tuned (timing etc) a reg service wont do much
have your injectors flushed as well
by having a exhaust system you will lose 50km or so

you really should be aiming for 10l:100km with a few mods

another good tip is to reset your ECU and reset you fuel mapping also, it helps a little
