This is because software when receive data from OBD divide value which receive by 4... Im try connect to OBD with hyperterminal and request rpm and convert value from HEX to dec and I get real values in this software show me values divided by 4... So is posible where configure something like calibration? Because Im looking to buy software which have gauges and I can calibrate values... I can write application(in Delphi) but without gagues, so this don't help me...
