This demonstrates how Hevnsnt at iHacked converted his North American spec 2005 ZX-R6 636 ECU to Euro Specs. The
2005/2006 model has an exhaust valve that's used to reduce the noise levels at the higher rev range. This was done
to meet US Federal noise standards. In the course of reducing noise, the valve reduces power levels. Modifying the ECU
to European standards will change when the valve is opened. This change usually results in an improvement of 10
horsepower in the upper rev range.

To covert a 2005/2006 North American ECU to Euro spec ECU, locate the unplugged 4 wire plug under the front seat.
It's the connector with rubber plugs on one end. This is how it appears under the seat. It will be taped to the
cable beneath it.
Close up of the block with the termination plug removed.

From another angle.
Open the connector up and locate where the black w/yellow stripe wire and aqua w/green stripe wire terminate. You can
either stick in a wire jumper to connect these two wire ends together or pull out the appropriate plugs and use proper
spade connectors in the cap to complete the circuit. Whatever you do, make sure it's isolated from other wires and the
frame or anywhere it could ground on.

Put everything back together, start it up and let it warm up, then take it out for a test ride. Remember that it will
only make a difference at 13k rpm and up, won't make a bit of difference below that and it won't sound any different
either. Now go find a person with an '05 and a slip-on and show him what he missed. Oh - I almost forgot, no FI light
problem either.
With the termination plug back on. It may be a good idea to wrap it in electrical tape to keep water out.
This is a quote from a 2005 ZX-6RR owner (599cc):
1st run. Stock 2005 ZX-6RR ran at 2:38:16 PM 92.5 HP
2nd run. ECU wires jumpered ran at 2:39:36 PM 101.7 HP
