Hey guys i got my headers, exhaust and CAI put in my car but its been running like realy rich, like i drain 1/2 a tank in a day like 50km tops.... and i wasnt hooning rtoo much.
My mate tells me i can disconect the bater leave for 15 mins then reconect and leave the car started in idle for 15 and the ECU will reprogram itself for the mods... is this tru?
i do it a diff way..
1. disconnect negative connector from battery
2. remove battery fuse from fuse box in engine bay
3. leave it for 5-10mins
4. put fuse back into fuse box, connect negative connector to battery again
5. start car, idle for about 5-10 mins.
this is for an ek though
shuldnt it work the same if i just take the whole batery pout and u reacon this will give me some better fuel efficiency?
yes it will definately give better fuel efficiency, you should usually reset your ecu everytime you make a mod to your engine (seeing as you've added an exhaust, headers, cai which are all mods that affect airflow.), or it'd probably just run rich. I don't know if it's the same if you just take whole battery out but i was taught to do it this way lol
50KM from a from half a tank is ridiculous, even if you were caning your car like a bitch. Sure there's not something else wrong?
lol i didn't read that bit, driving 50km and half a tank is gone? that's pretty shocking..even when i do alot of spirited driving with my car i still get 400+ km from a full tank
yer man car runs fine just goes empty in hurry... D:
yeah, i think you should try resetting your ecu, either my way, or whatever way you want to do lol. it doesn't cost anything so it's worth doing atleast.
is the batery fuse box that black rectangfle thing in the top left side of engine bay? and wen u open it upo theirs all these chips in different colours?
Yes,
BUT
Honestly,just disconnect both positive and negative for 5 minutes,reconnect,let it idle for 5 mintues,dont touch anything,turn it off,turn it on,done!
if you're using 65l/100km i'd suggest something else is wrong
that and your car would run like shit from drowning in fuel
i don't even know whether your stock injectors are capable of pumping that much fuel given the distance
Are you sure it is 50km / half tank? Where did you get that number from. Either your fuel gauge is faulty or you have a fuel leak for such bad usage!
well given the euro's tank is a total of 65l assuming the fuel gauge is correct
either way it's loads of fuel
The fuel guage never reads right too...
Like this was my log i had a FULL tank and went from rowville to monash clayton uni and back then to moorabin DFO and back and dwn to half tank D: no joke
LOL ye im sure coz i live in rowville filled up night befor to full and only drive to monash clayton uni and back then to DFO moorabin and back peak hour trafic but yer... half tank gone my mates mazda 3 had lost less than a fifth and he filled up same time as me
When they installed your headers, they might have stuffed up your O2 sensor (broke a wire or similar). You need to get your car checked out. Something is badly wrong. I have driven at full throttle 4000-7000 rpm in a day for 90 minutes and that only consumed 30L/100km.
HAHAHA fuel economy is good now guys chill i reset the ecu :D
thanks for the help !
resetting your ecu...... does that have any effect on the alarm system??
that's good to hear :)Quote:
