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.
