Evoscan 2.4 my coolant and air temp logs backwards - need fix

I'm not sure how I screwed this up, but my air temp and coolant temp logs seem to be reversed. Here is a fun little WOT log to show you what I mean:

Here is a screenshot of my Evoscan 2.4. Looks good to me.... By the way, should I adjust my injector scaling on the front of the EvoScan (see below) from 513 to what that value actually is in my ROM? If yes, what logging benifits will that allow?

I use coolant request 10 and fuction x*1.8-40
Air temp request 11, fuction x*1.8-40

It may be that somehow coolant is in *C?

Here are the complete definitions:

<DataListItem DataLog="Y" Color="" Display="MAF Air Temp Scaled" LogReference="MAFAirTempScaled" RequestID="11" Eval="1.8*x-40" Unit="deg F" MetricEval="x-40" MetricUnit="deg C" ResponseBytes="1" GaugeMin="-40" GaugeMax="260" ChartMin="-40" ChartMax="260" ScalingFactor="1" Notes="" Priority="1" Visible="False" />

<DataListItem DataLog="Y" Color="" Display="Coolant Temp Scaled" LogReference="CoolantTempScaled" RequestID="10" Eval="1.8*x-40" Unit="deg F" MetricEval="x-40" MetricUnit="deg C" ResponseBytes="1" GaugeMin="-40" GaugeMax="260" ChartMin="-40" ChartMax="260" ScalingFactor="1" Notes="" Priority="1" Visible="False" />

Ditch the old coolant temp and MAF air temp definitions.
