May just have to do that when I get my car back and have fitted an Induction kit.

It will still log error codes though just incase that doesnt solve it i think :thumbs_up:

Removed pointless posts seeing as this is about how to reset the ECU only.

 

[Mattie]

I personally think mine does need a resetting, if I fired her up from cold, she would idle at around 1100/1200 revs. Quick punch of the throttle and she would then settle down to about 800revs

 

[Lee]

That sounds like your auto choke on. Mine does it, sits at about 1200 revs until it warms up then drops to 800.

 

[Mattie]

Fair enough.

would this be needed for a drilled airbox and pipercross air filter

Mine is ok i think, i put a K&N on, but i may stil do this test, seems like a really good idea!!! cheers Lee

thanks lee i had a problem with my 3cyl ecotec engine it came up with a fault code saying it was a p0505 idle control so me being me read the manual and got the new part put the part in and still had the same problem i know the manual said you have to re set the ecu i never did it cos i never knew how so fingers crossed it should go like a wee rocket again he he thanks all for the great information yehaaaaa

Mines starting to mess about so I'll try this. I know its a stupid question but is it advisable to do it in this freezing weather? Cheers again Lee

The weather shouldnt really alter that much to be fair... although the engine to begin with is freezing cold, it will msot likely idle high as a result until its warmed up. Thats not a problem, its a design, its supposed to do that.

Also remember if you have your standard stero you need to make sure you have got your code cause it resets the stero disconecting your battery

Lee - my '99 1.4 CDX does this, is it a problem that needs solving, or is it just something certain cars do?

 

[Lee]

It's normal from what I'm aware.

 

[Root]

Thankyou, great guide, very useful.

will this also reset the automatic gearbox ecu on my wifes 1.4 si automatic,1994 model?

 

[dudedodd]

will this effect my central locking as the other day it stopped working when i disconected my battery but now it seems to be okay

 

[dragon2309]

is it factory fitted central locking? or did you fit it yourself?

it shoudnt be affected either way, central locking obviously wont work when the batteries disconnected, but once connected again it will function perfectly fine, theres no memory or clever chips inside a central locking unit, its fairly basic.

and to the other guy, about the auto gearbox ecu, not having an auto i dont know for sure, but i would assume yes, if it has no other power source, the same rules apply, any memory or saved states in the chips of the ecu will be wiped due to loss of power

Thanks. Car playing up when drilled airbox refitted, so I'll do this tonight and hopefully it will be fine tomorrow.
