when i try the disconnect battery for 15 minutes-- with the brake pedal method, to reset my ecu, i can't turn the ignition to "on" with the battery disconnected, so that i can depress the brake pedal with it in the "on " position. am i missing something? i have the intelligent key feature, if that matters.

 

Does nothing if you can't depress the pedal with the ignition in the ON position.
Alternatively, you can leave the battery disconnected over night.
Or just not worry about. The ECU should adjust over time, assuming we are talking about a relatively minor change.

 

Will this process work for a 2006 G35 6MT? Will the battery disconnect work? I have just given my car its first oil change and it feels like a fat pig. The tune is definately in Granny mode. When I floor it the thing doesn't even move until it gets over that initial build up of power but by that time the other car is gone.

 

Yes - they both work...

 

This is almost a joke.......it's like people can't read or comprehend what
there seeing. On page one you tell them how to and the very first post
asks a stupid question you've already answered. In the begining maybe
you should have told them to pull the negative side of the battery cable
and leave it off for an hour....then reattach.....then someone would ask
"how tight"............doooooooow

 

Why don't we just have a complet method of how to refresh the ECU?
someone?

 

Been there - done that...MANY times...

 

Ya, I actually saw the post of yours, website of technosquare, gonna give it a try. but i just thought it would benefit other member to sum up the methods

 

Worked for me. Not sure if it made any difference or not.

 

Does resetting the ECU make any difference to anything if you always use the manumatic mode on an '05 sedan?

 

On my other car I could just pull the fuse to the computer to reset it. Will that not work/not appy on the G35?

 

Yes.......

No info on that.
The only methods I know of are to do the pedal type reset and the battery disconnect type reset.

There isn't a dedicated fuse for the ECU - it is shared by other components, but I don't know which off hand. It also uses a reverse loop ground, and that's why removing the the negative battery terminal works best, as all ground is lost and the loop will terminate.

I see, thanks for the reply guys!
