Used your ECU removal instructions to flash my ECU and they are very good, Thank you.
I bought a flashtune kit and proceded to flash away. I will do a ride review tomorrow and see how things came out.
I just did some basic things and loaded an M4 fuel map for an FZ-09.
Here is a picture of the flashtune software and what I accessed (nothing changed above ECU SETTINGS):

You know for LESS then what you paid for the flashing stuff, you could have had it flashed by our vendor for less AND have it be perfect?

I like to tinker and you do not know what I paid nor do I want the down time (ya, maybe only one week, but.....).

Not sure exactly when after removing the tank fasteners, but you can just twist the tank 180 degrees and not have to disconnect all the power and hoses.  Worked on the FZ and on the FJ.  Just rotate it and set on seat.

I'm with ulewz, where'd you pick up the flash software and cables from mate? Pm me if you need to, I'm a tinkerer by trade! All respect to 2 wheel d/w but I'm too far away to send my ecu anywhere and it'd be cool to have a looksie inside, do they supply generic maps like power commanders?

After taking a nice spirited ride to lower the fuel level, I jumped in confidently, after viewing your post and pulled the ECU. Thank you for this thread mjsracing. It took me a total of 30 minutes after reading your post. Without this, would have taken me quite a bit longer with all the fasteners. :):)linky

I could not get the ECU plugs to release, so I took the tank all the way off just to get it out of the way. The fuel line has a orange connector lock that you slide over to the big hole and slide the orange connector lock off, then then there are two buttons on another connector that you squeeze to disconnect the line. You can see the orange connector lock a few pictures above. Be careful to not scratch the tank on the bottom of the handle bar, which I didn't do. But the bottom of the tank did scratch the frame up by the motor, I just was not keeping close enough watch on that and got a few small scratches on the frame.

Great instructions and photos. Thanks! You saved me a few headaches and some head scratching. FYI you can still access the ECU without disconnecting the hoses and fuel pump by just putting a stick on top of the airbox. I used a PVC pipe and it worked no problem. Also, for those who are having difficulty removing the ECU connectors, just use some needlenose pliers.

I managed to get the ECU out by myself with a full tank. It wasn't easy but I found that wedging a flathead screwdriver underneath the clips and they popped out. The retaining clips that hold the ECU in were the more difficult ones but again, a flathead screwdriver and some dexterity with my right hand helped slip it out.
