Unhappy ECU will not reset!

Well after putting on my borla exhaust today I went to go reset my ecu. Well I used the gas pedal method and it didn't work. I need some help I am not sure if I am doing this right or not.

With the car having been off for at least 10 sec.
Turn the key to ON (not start)
Wait 3 sec.
Pump the gas to the floor 5 times whithin 5 sec.
Wait 7 sec.
Press gas to floor and hold 10 sec.
When S.E. Light starts blinking, release peadal
Press again and hold at least 10 more sec.
Done.


This is the method I am using, and once again not getting anything. Am I counting to slow or not slow enough? I am not sure. I went to the dealer to see if they could do it and they have never heard of it.

So I need some help on figuring out how to reset this thing.

Any help or suggestion would be greatly appreciated,

-David

I have never heard of that method. Where did you hear that from? I thought that if you disconected the battery for 24hr the ECU would reset.

does disconnecting the battery for 24 hours really reset the ECU or do you have to do it this way?

24hrs. that seems like a long time to reset the ecu. I thought you just had to disconnect the battery

It doesn't really need 24hr to reset the ecu... the ecu on my 99 Prelude SH will reset in minutes, but lots people told me the longer you disconnect the battery the better, so just unplug it and leave it over night

It took me ten times to get the this method to work. At first I thought this was some kind of joke going around, but after some practice and a watch with a second hand I got it to work.

Precise timing is critical. If you are off even a second on any step it won't work.

Keep trying.

not sure if this is valid, but I pulled the ECU fuse by the battery compartment, and let it sit for about 30min. Put the fuse back, and went for drive. My car seems to be little stronger.. but that could be just me
