Tiger Dyno'd

Plug colour?  First, that'll do for carbs, but isn't an accurate gauge for FI engines, you need exhaust analysis.  Second,  you said you were running iridium plugs....... :roll:

I can understand why your experienced friend thinks this is not worth fixing for the reason I gave earlier.  Doesn't mean you don't have an issue though,  the graph speaks for itself; you said in your first post,"I think it´s a little bit poor"  .... the graph is telling you why.

All these fuel mixtures change only, the fuel map. But normaly when you change fuel map in carburator engines it´s better if you change also ignition timing. Because the ignition timing can also lead to detonation also if you squishband is too small.

Yes, I´am going to change the map because I look those plugs today and it´s have to change. Now I just wondereing which system shall it change :?: Power Comander is cheaper than Tuneboy, from Sweden I can get PC 260,- euros and TB is nearly 500,- euros same as rapid bike.

I didn't mention the timing because we were discussing the weak mixture as shown at the top end on your dyno graph, but you're right, timing would cause detonation or running hot too.

In Tuneboy you can change the timing map, just like you can change the fuel map, or the AF target map, or the full power map, or the cold start adjustment.  Not to mention read and reset fault codes, reset the throttle position sensor, read all sensor outputs, blah, blah.
 
Power commander just changes the ECM output to the injectors.  I have experience of both, I have Tuneboy on Tiger and PC on my Blackbird.

In the end, it's down to personal choice. Good luck with whatever you decide.
