resetting an ECU?

how do you reset your ECU. i know curly2k3 knows hes told me how to do it before at one of the meets. i just forgot.

can someone tell me how to do it?

 

pull +cable off battery.. press brake pedal for 10-20 secs.... let sit a while.. reconnect.. should be about it

 

nates gay i mean right

 

iirc don't you also have to let it idle for 10mins?

 

no just take of the cable push the brake to the floor hold it for 30 secs. to be safe and throw the cable back on..

 

crap...so much wasted gas and time.

 

I've heard its the neg cable, I spose it wouldn't matter but thats what I heard.

 

How would you let it idle if you disconnected the battery?

 

After you reconnect the battery.

 

You don't have to let it idle or do anything fancy. Just unplug the battery and you're fine. You can also reset the ECU with a laptop and RomRaider or ECUExplorer.

 

yea i did exactly what tstrboy said to do and now my car runs like a ****ing champ!!!!

 

Probably a stupid question here...but here it goes!

When resetting your ecu, does that mean you lose any tune you have on your ecu? Does it revert back to it's stock map after resetting?

 

Ya positive is always on the longest.. reduces spark/arcs. So pull off negative cable.

 

this ^^^^^

 

Nope, there is no way to lose a basemap tune, short of reflashing or getting another physical ECU. Resetting the ECU loses all the RAM data, which includes AFR and knock learning numbers.

 

I dontwant to jinx myself so my hesitation comes back but I am now a firm beleiver that everyone should reset there ecu every 6 months or before and after winter or summer. That is all.

 

Not on a positive ground car.
