how to reset ECU???

[rolakers]

There used to be a thread on here about how to reset the ECU but I can't find it anymore. Could someone help me out??

The reason I wanna do it is because I'm having a header put on and I heard that ECU should be reset. Thanks guyz.

That works, or you could try to start your car with the ecu fuse pulled, if you don't feel like reseting your radio.

Notice I said try, cause nothing will happen, it'll give power all around, which will clear the system of excess power, while no power is going to the ecu, therefore reseting it.

because when you disconnect the pos. and neg. cables there isnt a constant source of power for your stereo to remember your settings.

Right, and if you start your car, after removing the battery cables, and your radio didn't reset. Chances are neither did your ecu. THis is the excess power I was speaking of.

if you're worried about this, follow my method of reseting the ecu.

Park your car at night, unplug/uninstall your ECU. Then the next morning when you need to go to work/school/wherever, reinstall it.

That would in theory work... I guess. But its a lot more work then pulling one damn fuse. I mean come on man. This thread shouldn't even still be going on.
