DSM / Eclipse 1995 Evoscan Coolant temp RAW x Scaled

Ok, here is the problem: the supplied eval for coolant temp is

Coolant Temp 07 -1.45x + 308 deg F

gives a wrong temp, starts high and lowers as the car is getting warmer.

After a lot of search I found that if I use only x as eval on request id 07 I get the RAW coolant temp in Celsius.

I tested this and seems right BUT the ecu uses the SCALED / CORRETED value for turning fans, etc...

So the eval for scaled coolant temp should be x-?? (as the raw its a little higher than scaled)

Anyone knows how many degrees the raw and scaled differs on the 95 dsm?

Or if some one have a ir/laser thermometer it could easy log requestid 07 with eval x and see the the difference with the thermometer.

Sorry for my english, and thanks in advance for the help.

Code:
<DataListItem DataLog="N" 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" />
That's what you should have for Coolant Temp Scaled. Put that line in your Mitsubishi MUTII file located in your Evoscan folder.
