Resetting your ECU with BIG`O

[Simmo2302]

even if that is tru and the ecu will re-learn to be fuel efficient, how long will that take ? it may take a week of bad fuel economy b4 it goes good again.

i have a 2002 civic and when the ecu is out, i can go thru up to $10 of fuel a day, thats shocking compared to what it usually should get.

i'd rather reset the ecu and get good fuel economy straight away, than wait till the ecu re-learns to be fuel efficient again.

well thats just my 2cents neway

so how to reset ECU for prelude 99 BB6 anyone?

can i just disconnect the battery (remove the + or - terminal?) and then turn the car on after that and let it idle for 10 mins, will it be the same shiet, instead of going to take out the ECU fuse from the fuse box

[trism]

its the same for every car

you can either remove the fuses, or disconnect teh battery fior 10 mins

connect back up, turn on, let idle for 10 mins

im more inclined to remove the fuses, but im just unsure which fuses they are on the bb6

so by disconnecting the battery, means unscrewing the bolt on the negative terminal, and then taking the lead off rite??

[trism]

yes.

the fuses will be labled ont eh fuse box. if you are still unsure, take sme pics and someone should be able to show you

** why is the prelude bonnet so farken heavy -_-**

ok anyway, so i am just going to pull the 7.5A / Clock radio fuse for 3 mins and then idle for 10 mins, thats all ay. sweet thanks/

[trism]

that wont do shit bro

the clock radio fuse is not the ECU fuse

just rip off the battery terminal for 10 minutes

then idle for 10 minutes

[MWAKU]

hmm then whats everyone going on about in this thread of the clock radi 7.5A fuse :S:S:S

which fuse is the back up ECU


i don't really want to disconnect the battery as i cbf to restore the headunit settings, and i don't know if theres a code on it, bought my car with it.


** wouldn't this be it, except there 10A is our 7.5A i think

btw nothing is labelled ecu reset

[trism]

take a pic of the fusebox and fuse diagram. like i said before

someone will tell you

[MWAKU]

Ok here are the pics, as you can see they are blurry as cause its my fone camera..

well the 2 brown fuses are the 7.5A.. one along with the rest is the clock radio one, and the one the just under the is the other 7.5A (under the 10A hazard)

[trism]

well you dont remove the clock radio one. as thats jsut for the clock and radio. if you do that, youll **** the radio, and maybe need a code. its jsut like disconnecting the battery.

[MWAKU]

Oh ok, now im confused, one person is telling me that i remove the clock 7.5A one, and your telling me it won't do anything lol.

wells, i guess if i remove the fuse it would be easier then d/c the battery.

what does the 7.5A do thats not labelled do if i remove it
