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

[fezp]

thanks, how mcuh is it for a sensor replacement? or to get it checkd out?

yeh i had to fill up at 380.. i got scared the light came on.. then started coming on more frequently at 382.

i still haven't ruled out that im just a shit driver being new to manual and all. but i mean i shift every 3-4ks and still dont get much outta it and here ppl are gettin 400-500ks and they're hittin it hard.

[theHKway]

when the light is on
you still for 6-8 litres left
but dont bet ur life on it. hahaa

its all in the manual

[Rexxy]

i dont know if this as been answered
but if you read your manual, you should be shifting around 2700-3000rpm

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

Chris

shifting at those rpm's might be nice, but then it is a long way from the 5400rpm vtec engagement, not vtec no fun lol.......

if i could get a typeR that is Stock to get 10/100 then my prayers had been answered....but to get a mod'd R at those stats i darent say is possible....

if my wife has the R for a week or so, and she granny's it......i.e. gear changes well under vtec, she will get 400 per tank.... which is maybe 12 or 13/100

thats on my car anyways...

[tinkerbell]

craig, most modded cars that have ECU tune will provide *better* fuel economy than one running on stock ECU...

by 125kW B20VTEC gives my 9-10 litres per 100km city... and as previously stated, i have got close to 6.5l per 100 on the Hume...


just to clarify for ALL - if you are NOT getting close to 10l per 100km in a DC2R - it is likely your car has a problem.

[Rexxy]

u lucky bugga(s).....

so this then gives me ammo to use in convincing the wife that Modding my car will in fact assist in improving fuel economy in light of the impending fuel price increases...lol

no mod's, no need for an ECU tune or new ecu.....


i am not getting 10/100, but i know its me....not my car......2 engines, same fuel economy from both.

[tinkerbell]

well, here is THE thing:

because our cars are tuned by Honda for 95 octane, by tuning a complete stock car with ECU like PowerFC on 98 octane will improve BOTH power and economy.


BTW - if your car is not getting great fuel economy...

go and reset the ECU first of all:

got to the engine bay, remove the fuse box cover under the bonnet, using needle nosed pliers (or similar), gently take out the small blade fuse marked radio (NOT ECU) and leave it out for 10 secs...

reinstall fuse, and start car, letting it idle (without touching the throttle) for a few mins...

car has been reset and is going to have forgotten any "long term fuel trim" parameters that may have been stored up...

[Rexxy]

u really r a guru..... ;-)

is this any difference to what i mentioned about adjusting timing up +1 or +2, would just doing this burn more fuel ?

[l3vnd1]

Off the topic; would running a 7point increase octane booster on a 98 RON fuel be detremental for the engine? THen it would be around 105RON fuel.

most octane boosters do shit all and aren't worth the $$

well, the injected fuel would be the same, it would just be ignited earlier (if you meant by 'adding' timing you menat going from -16 to -18 BTDC)

this would perhaps burn more of the available fuel due to the longer amount of time it has to burn, BUT it also might cause it to burn too early and actually put a reverse force on the engine (detonation).

however, it is my understanding that IF the octane rating of the fuel is higher - it will actually have less propensity to detonate and THEREFORE, adding more timing will result in more power/better economy.

BUT

the only way to tell how much timing to add, is on a dyno or via road tuning... which is a lot of expense.

you may as well get a programable ECU and pay the 500 for the tune on Optimax/Ultimate and be done with it...

AND

as for the mega-hyper-octane booster, this is only beneficial if you have a non-street car IMO.

detrimental?

maybe, octane booster damages delicate sparkplugs, like the ones with precious metals - check with your spark plug manufacturer whether the ones you have are OK to use with octane booster...

otherwise, no, BUT they are detrimental to your wallet i guess?

[Elwood]

I use 5th gear a lot.


Petrol prices hitting $1.60 is ftl.

[tinkerbell]

you notice a drifference driving like that to the tank?

[l3vnd1]

I always cruise in 5th.

IM gunna do this as well. I thought disconnecting the battery for 10 mins reset the ECU also, I read thaton here or over at ClubRSX....
