Re: low voltage problem
I would check to make sure the ecu and the actual measured voltage is the same.
If you are only getting 11v probably a bad regulator on the alternator. I would get that checked out.

Do a load test on your battery with a multimeter.
If the battery has less than 12v with the car off you most likely have a bad cell in the battery.

If im reading the datalogs correctly, your only having a low voltage problem higher in the RPM's, so I would check the belt, if the belt is fine, I would replace the voltage regulator/ALT
