I saw it on a thread here somewhere, someone had a 'special' tool, which was basically an paperclip with electrical tape on it to jump something on the ecu to reset it.

Can anyone shed some light on to where I saw it ? or does anyone have some nice directions they'd be willing to write up for us ?

I think I remember seeing it in the air box mod thread. I did it but I forget the procedure.

Turn ignition switch off, remove seat, remove DLC (Data Link Connector?) cover, short DLC terminals using the special tool (The pins to reset the ECU are attached to the Green and Blue wires on the harness. ) , open the throttle grip fully and hold, turn on ignition switch. The MIL light should come on and start blinking rapidly, with in 5 seconds after rapid blinking starts close the throttle grip and hold for more than 3 seconds.

Note this does not work if a code is stored on the ECM the code must first be read and removed. If the rapid flashing does not happen you should check for a code.

Here are a couple of pictures. Wires to short on the harness are blue and green with black stripe.

When is this needed? I thought the ECU adapts to changes automatically....

He is a scenario. Your dog has been shitting in the house his whole life. Now you need to train him to go out. This could take a little while, right? He's used to the carpet and it's hot outside.

Resetting your ECU is like getting a new dog. You train him to drop a deuce in the backyard at the very beginning. No learning curve and instant results. LOL

I look at it this way... It doesn't cost anything and it only takes a minute. The ECU already keeps the engine running as lean as possible for emissions compliance. When we open up the exhaust, the engine breathes better. If the engine runs leaner, you risk detonation or at the very least you don't see the fuel to go with the extra air which means no extra go while you are waiting for it to learn to not shit on your carpet. Without resetting, the ECU will still adjust but at a slower rate as it learns. This is why people start to see increases after 50ish miles of riding if they don't reset. It is conceivable that damage could occur but who knows. I doubt it would. Resetting gives the gains sooner.

Why not reset it? It couldn't hurt.

I would reset anytime you significantly change intake, exhaust or fueling.

last nite it felt like my bike wanted to give up. what that my ecu thinking? this was after a 50mph max hill climb for about 2min. at the top when it started to level out i expected the mph to climb back up as usual, but instead it stayed at the 50mph and almost felt like i was losing power.

and fyi. in the image. its the red plug electric taped to the wired tube thing. the tube thing is secured to the frame, but if you unclip the cap it will free up some room to jump the plug. the wires to that plug you have to jump isn't secured to the frame like the wierd tube thing.

Special top secret Tiller1k tool. If it looks like a paperclip, that's because it is.

How do you see if there is a code on the ECM?

Are you supposed to actually leave the "special tool" plugged into the plug or just a quick touch to the two terminals?

leave the jumper in, throttle fully open, turn ignition switch to on. wait for flashing engine light, release throttle within 3 seconds.
