0-5v output

 

 

Is there a dedicated 0-5v 3D table i can use to set up my WMI up on. I want to set a dedicated feed to it via load vs rpm in 0-5v format so i can inject a certain amount at a certain point?

 

Thanks

There is not a "3d" table

There is not a "3d" table that references an analog input on the y-axis and engine speed on the x-axis.  You can use the User PW table which does reference a selectable analog input but it doesn't also reference engine speed.  If you're progressively driving a pump, you're using a solid state relay to do so, yes?

Its AEM own 0-5v WMI kit that controls the pump

Hmm well that's not really

Hmm well that's not really how this works.  The 0-5v WMI kit is meant to tap onto a 5v analog signal coming from a sensor (MAP, TPS, etc).  There definitely isn't a user configurable 0-5v output from any AEM EMS.  I'm not sure if that's a standard output on any aftermarket EMS honestly.  So you could either tap onto one of the analog sensor inputs going into the EMS-4 or do what I suggested aboved and have the EMS-4 control the WMI by driving the pump through a solid state relay.

Hmmm. The FIC has this

Hmmm. The FIC has this feature via analog output. 

Yeah ive had it on IDC for a while but i wanted to supply a bit more lower down in the rev range

Yes the FIC does have analog

Yes the FIC does have analog outputs because it's meant to work with OEM ECUs and try to keep them "happy" by hiding boost or additional fuel, etc, which it does by manipulating analog signals.  The EMS-4 isn't designed to work in this way so it does not have this functionality.
