Reset E.c.u

[podgey]

hi, i am going to reset my ecu in the morning. my question is do i have to turn engine off before pulling fuse out?

is this right

1. warm car up by driving

2. stop engine

3. pull out fuse

4. step on brake 3 times.

5.put fuse back in

6. start up engine again.

thanks podge :)

do it from cold - take out efi fuse press brakes twice wait 30 seconds , put fuse back in , hey presto.

[podgey]

is that with the engine off? cheers

sure is mate, you could just disconnect the earth from Battery if its any easier.

Will removing the earth strap reset the E.C.U alone Maleborn?

I mean without having to press pedles, do a morris dance and sacrifice a lamb?

[Fidgits]

the pressing the brake pedal is just to take out any charge left in the car (the brake lights drain the charge)...

and taking off the earth wont do it - youd need to remove the live connection...

Don't disconnect the Battery - it'll b*gger your alarm (as Lord Ed will tell you).

And do it warm so the engine is at operating temp .. makes the initial running in process quicker with a warm engine.

I pull the EF and EFI fuses out the engine bay fuse box. Mine is a rev2 and others will be different.

You can say that again!...

I have tried all the stuff above and still no joy... we (bibbs 'n i) came to the conclusion that the Rev 3 is different...

You should get a rough idle at startup... IF it has worked..

Just disconnect the ECU .. and leave it for 5 mins ..

if its easy enough to do.. i may just do that before i leave work today..

[Bibbs]

pull back the boot lining .. pull out the three blocks at the bottom of the ECU ..

Then leave it 5 mins and plug it back in ..

Cool.. i'll give it a shot...

ive no clips holing the lining in place so that first part is easy.. and if its worked i should get a rough idle.. fingers crossed!..

cheers

[Bibbs]

rough idle is sometimes apparent .. othertimes it's harder to notice ..

I blip the throttle and then it'll usually hunt about 600 rpm.
