Summary of change:
'' '''Engine Coolant Temperature Related Configuration Parameters''' '' * Traditionally coolant temperature range was -40..+102C, and had to be selected at firmware upload time. ** Since many engines regularly exceed 102C coolant, installers often cheated and uploaded 1900/256 hexfile instead of 2252/256 so the reading is appr 10C lower around 100..110C (this extended the range to 112C) * With '''1.1.50''' or newer firmware, one can '''select Celsius''' (not Fahrenheit) based coolant table during firmware upload (eg. 2252/256). This way the '''maximum coolant temperature is 155C''' (range is -100C .. +155C). LCD and VemsTune / MegaTune communication was changed to reflect this(and show temperature that matches the internal representation) The ''flash table'' is chosen in the ''settings/constants'' dialog: http://vems.hu/download/v3gui/images/VemsTune-constants-dialog.JPG Alternatively, the ''17-point curve'' can be chosen. * with 1.1.50 or newer firmware, coolant and MAT can be configured with a 17 point table: http://vems.hu/download/v3gui/images/VemsTune-coolant-curve-dialog.JPG While the traditional flash table must be selected at firmware upload time, this 17 point curve can be adjusted later, and easily matched even to special-custom setups without programming knowledge.
