Power Reading too High on iPro

[robsp8]

I've just brought a new bike and moved my iPro onto it, and it now sits slightly higher than on my old bike.

I've done a cali and coast down test.

However, my power reading when on the flat or going downhill are not correct. In fact today, when I was on a 0.03% decline I had watts of around 170.

This only happens when I am pedaling though, not if I'm coasting.

I do all the usual set up techniques and have stopped mid ride to do them again.

I've got latest firmware 4.26 and cant see what else I can do. The iPro is nearly 2 years old

Anyone have any ideas why, or what I can do to resolve the problem.

Thanks

Rob

In the ride file you submitted there is no wind speed data whatsoever.

Please repost file, preferably in .ibr format (as downloaded).

Hi John

Here is .irb format

just on another problem, my compute keeps (about every 5km) resetting itself i.e it stops picking up cadence/speed and HR and then scans to pick them up.

thanks
