lostsoul Posted March 21, 2020 Report Share Posted March 21, 2020 I have WMI so I want the Waste Gate solenoid to be turned off if certain conditions are met eg: if either the WMI tank level is too low and/or the failsafe system is activated. How can I do this? .... Can I do this ? Basically the setup I want to run is .... Flex Fuel with WMI full time from Waste Gate boost and up, hence the need to be able to switch the Waste Gate off. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
lostsoul Posted March 22, 2020 Author Report Share Posted March 22, 2020 At the moment I have the Fail safe flow sensor connected to the ECU on DI3. The Run Time shows that this is active ... does this mean it is sending voltage to the ECU? Quote Link to comment Share on other sites More sharing options...

If it is set up as a frequency input then it will show active when there is a frequency greater than about 1Hz. If it is set up as just a GP input with on level high then it will show active whenever there is more than about 1.5V on the input. If it is set up as a GP input with on level low then it will show active whenever there is less than about 1.2V on the input. 11 hours ago, lostsoul said: Basically the setup I want to run is ....

Are you using open loop or closed loop boost control? Quote Link to comment Share on other sites More sharing options...

Will be using Modeled Multi Fuel so will be using 2 blended waste gate tables and open loop boost control. Quote Link to comment Share on other sites More sharing options...
lostsoul Posted March 23, 2020 Author Report Share Posted March 23, 2020 The Boost Solenoid is on aux8 set to "Boost Solenoid" ... could I change this to "GP Output" to give me some logic conditions? Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 23, 2020 Report Share Posted March 23, 2020 No, there is not much you can do software wise if you are using interpolate mode. Your only option would be to use another aux to turn a relay on/off that supplies power to the wastegate solenoid. Quote Link to comment Share on other sites More sharing options...
lostsoul Posted March 23, 2020 Author Report Share Posted March 23, 2020 How would I do that ? ie: how would I setup the aux output and conditions. Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 23, 2020 Report Share Posted March 23, 2020 Say you had DI1 and DI2 as your WMI level switch and WMI failsafe input. Set up below would only turn on the boost solenoid power if both of those DI's are off. Quote Link to comment Share on other sites More sharing options...

lostsoul Posted March 30, 2020 Author Report Share Posted March 30, 2020 The Fail Safe sensor is a flow sensor which sends 12 volts when the flow drops below a set level ... how should I set up the "Pullup Resister", "Input Latch" and "On Level" ? have wired it to DI3.

Adamw Posted March 30, 2020 Report Share Posted March 30, 2020 Pull-up off, latch off, on level=high Quote Link to comment Share on other sites More sharing options...
