Does the maf converter need to be tuned under load? Or can it be done in neutral?

First points need to be tuned at neutral with "end interpolation" turned on.
This will give you some table, which provides you to drive vehicle under load and tune other points under load.
Typically users got some table with normal driving from 0 to 100 km/h.
Because high speed is dangerous, our users typically make tuning upper points manually by analyzing log file.
They make log file on 2nd gear from 1500 rpm to red zone with fully open throttle( power mode) . In this case( on 2-nd gear and throttle fully open) you will not get a speed more then 100-120 km/h , and log will show you mixture problems. If it's too rich or too lean in this mode, it should be corrected manually by analyzing log.

How do you tune the temperature sensor?

IAT should be connected to the ECU and to the converter( no more constant resistance). For example you make tuning at 20C and you will see square on dashboard chart, which will show you signal in IAT ADC value and corresponding correction.
When it will be colder, there could be problems with mixture.
To correct it, you will need to enrich / enlean it manually, but don't apply correction to table - this will give you knowing of needed correction.
After that look at new value of IAT and write correction you got to a point corresponding to new IAT's value.
