Have you discussed this issue with your tuner?

[jdouille]

He is in Asia to learn to map the new Honda 1.5l turbo unfortunately and CPL RACING do not help me from England.

Have you see the voltage fluctuation to Primary & O2 sensor ?

Best regards.

Have you tried re-uploading a saved copy of your calibration to the ECU?

[jdouille]

I had to save the hred map on my computer. I tried to add the launch control and send it back to the ecu, it works, I see the changes but still the same problems.

Instaled a decata without modifying the map can damaged?

It's possible to reboot the kpro ?

[Spunkster]

You should try contacting your tuner for the original file they tuned it with and see if that resolves anything.

[jdouille]

is it a map problem?
Because the problem us appeared suddenly without any change.

It's possible cause odyssey pc680 battery, even fully loaded ?

Most strange are Primary sensor at 0.00V with engin power !!! And voltage fluctuations.

Thanks
