K8 Gsxr 1000 Clutch Switch

As above, has anyone had any experience of what problems occur when just connecting the wires together rather then putting through a relay or toggle switch.
I have read that it puts the Ecu into a 'Neutral' map using retarded ignition and different fuelling resulting in lack of high end power?
Also causes the engine to cut out/stutter on over run with the throttle closed?

I know a lot of people have K8's in cars so wondering what you have all done or what problems you have come across in getting around this?

Cheers
Tim

Tim, thats correct if it sees the clutch it limits at least top end revs. I use a toggle switch at start up as the ecu expects the clutch in at start up, a toggle switch is so much easier to wire In than a relay.

Ok, has your Ecu been flashed? Mine has but has had a problem for some time especially on over run its jerky and stalls throwing up code c40. Also been lacking in top end power in high gears.Clutch Switch has been joined together so going to re wire to a switch. I wonder if it's staying in a 'neutral' map and not seeing the flashed map because of the clutch switch being joined.

Kind Regards
Tim

Sounds like thats the issue.C40 indicates an issue with the ISC Valve (idle speed control valve).BTD
