Hi
I have an Mk with a k6 engine. I have a fault somewhere but am not scratching the head a little. I noticed that the 2nd stage injectors were not
coming in at the upper revs and about the same time when the revs increased, the butterfly flaps start to close. I have found that if you disconnect
the gps that it works at full power with 2nd stage injectors and flaps operating as you would expect. That down side is no display on the clocks. Has
anyone else had this or can you think of any reason why this is happening ?
Cheers
Rog

Don't some of these bike limit power in the lower gears to stop the bike flipping you?

Which suggests you only get secondary injectors functioning in gears 4,5 and 6.

Sorry I don't know much more about those engines.

This is 'normal' behaviour for the lower gears (and extended in neutral) in no-fault condition, abnormal for the higher gears in no-fault condition. You'll (hopefully and normally) get an error code for any serious fault that the ECU may be imposing a limit for. 6th gear by the way, imposes an ECU limit based on RPM and speed. It'll knock the RPM down a further notch in 6th if it can't see a speed sensor (error code). It won't throw an error code, but will limit things in the way you describe, if there's no clutch/sidestand interlock interaction in the start up phase.
I know what I am proposing is not a cheap solution, but I have a K8. Had issues with fueling a few months ago and for the life of me could not figure
it out. Ended up being something simple, but without being able to see whats happening, or rather seeing what the ECU is seeing, it gets difficult to
guess.
With all that said, I go the Woolrich Racing ecu kit and now I can log whats happening, or watch it realtime.
Not only that, now I can tune it to match what I want etc etc.
Might not resolve your problem, but it can definitely tell you whats happening. In my opinion, worth every dime.
