MERLINS RALLIART & EVOLUTION-X TUNING GUIDE11.05-INTERCOOLER SPRAY CONTROLThe seven parameters for controlling when the intercooler spray is activated areshown below.To get the spray activated, all the “Min” variables have to be exceeded ie these actas an “and” function. These are as follows:IC Min-RPM, the minimum RPM that IC spray can start to operate.IC Min-Water, the minimum engine water temperature above which the IC spraycan start to operate. There are two parameters, On Temp and Off Temp in degreesCelsius. These provide some switch on to switch off hysteresis.IC Min-Load, the engine load has to be above this value for IC spray operation.IC Min-TPS, the minimum throttle % above which the IC spray can start to operate.There are two parameters, On % and Off %. These provide some switch on toswitch off hysteresis.IC Min-Air, the minimum ambient air temperature above which the IC spray canstart to operate, in degrees Celsius.The spray will cease when the set speed in kph is exceeded - lots of air coolinggoing on here. The timer data are simple on and off periods, like a slow duty-cycle,defined in seconds.Shown below are the intercooler parameters for the EVO 9, hopefully theparameters for the EVO X and RALLIART are similar and found soon.Figure 74:INTERCOOLER - SPRAY TABLES, Evo9In the screen-shot above, the definitions have been edited such that the functionlabel can be read more easily. All the “and” parameters are on the top row.The “On Time” and “Off Time” have been altered from factory.REV: 0.K merlin@three.com.au Page 103 of 134
