Hi,
I have an AJP PR7 motorbike that has the exact identical MT05 ECU and uses PCHUD for diagnostics.
As I live in an area without a dealer less than 5h drive away I am trying to troubleshoot an issue myself.
Could someone shed some light why my bike idles inconsistently and also dies at idle speed ocasionally?
Here's a video (I am having difficulties running the PCHUD program, it keeps disconnecting, I can only have it connected for a few seconds and then all values disappear and COM port times out. I have to switch to a different USB port and another COM port then it starts working again for a few seconds.
Could it be a poor electrical connection somewhere? Bad cable?)

Things I have done already:
1. replaced the O2 sensor with brand new
2. cleaned the throttle body along with the IACV motor
3. tested fuel pump pressure
4. tested and cleaned injector
5. replaced fuel and air filters
The bike only has 4000km and is not even a year old.
An additional symptom is that the bike does not run nicely when riding at constant speed, let's say 4th gear, 3500 rpm, it feels as if it looses powercycles occasionally. When full throttle, bike goes fine and really strong.
