Thank You gays for all you suggestions.
Last night I have un plug the IAC stepper motor and the idling speed it was
unstable when engine was cold (to slow). So the IAC somehow works.
Some time ago I have clean all throttle body and replace all O rings and this didn’t help.
My bike is runs good in all the other time, ( so the MAP sensor do some work to).
The problem is only when idling and under the power load.
At this moment I don’t have working software to connect to my bike.
I have the red China cable but can’t make work with PCHUD.
Any suggestion what software to bay and where?
NzBrakelathes – so the Throttle butterfly valve should be fully close ( max 1% open), and all needed air should go thru IAC when idle?
So what’s the process to set this butterfly valve to 1% ?
I know about the trick ( 5 x on and 5 x off) after this only the Idle speed is OK even under the power load, but after some miles is back to the same issue ( idle speed dropping down when under the power load )
So can you help me to porches the correct software for this bike pleas.
I do not plan to do remap in the ECU but maybe small changes with plenty of records before.
Thanks
