I didn't see any loss of sync in the logs you posted.

yes, you are correct

but sometimes, it happens, 1 time in 10 minutes for exemple.

i just need to know if this kind of values are good for a 60-2 wheel ,

The readings in the logs you posted are good.

But if sometimes they are not good, it would help me to see a log of HOW they are not good.

The composite log shows a noise pulse on the crank signal. Try the noise filtering settings.

i fixed the ecu on is place,
turn on the noise filter

i have done a few miles with the car and seems fine,

the problem of the noisy logs, persists, and with the car runing on the road, its worst than on the dyno.

i thing my EEEpc mono Core laptop dont have speed for this.
