craig davies Posted February 2, 2011 Report Share Posted February 2, 2011 hi guys, im going to be tuning a mitsi cyborg soon uses 4g92 mivec engine which has a solanoid to switch profiles on the cams at a set rpm range, i was wondering for this solanoid (12v) do i use one of the ecu's digital inputs to trigger when i want the solanoid to activate? thanks in advance Quote Link to comment Share on other sites More sharing options...
Cameron Moore Posted February 3, 2011 Report Share Posted February 3, 2011 Hi Craig, The ECU will use it's trigger inputs to measure RPM. You will then set an Auxiliary output (set to GP output) to ground one side of the solenoid (the other side should be connected to an ignition switched 12V supply). You can then choose what RPM the solenoid will switch on and off at. You can start by using the RPM that the factory switches it at, or do a dyno run with it on and compare to a run with it off. Then select the RPM range where the performance is better. -Cameron Quote Link to comment Share on other sites More sharing options...
