RX8 metering oil pump control

[Richard Hill]

Good morning,

I am setting up a base map for an RX8, I have wired up the metering oil pump and assigned it to AUX 5,6,7,8 in PC Link.  How do I assign the input for the oil pump sensor?  In the RX7 I see it is an analog input with a table controlling the % of oil delivery.  The RX8 has a switch, how do I set up this switch in PC Link?  Do I connect it to an analog input and fudge the Oil stepper table somehow?

 

 

Thanks in advance,

  Richard.

I dont think you are going to be able to control that.  The rotary oil pump function and the CL stepper function both need positional feedback, they dont keep count of "steps" etc.  I have never seen an RX8 one but it sounds like it must be open loop, the switch is possibly just a home/reset counter type thing?

Thanks for the info, does anyone know if an rx7 metering oil pump can be installed on an rx8 engine (13b msp) ?  That way I could use the rx7 control strategy 

 

Thanks,

 Richard.

I'm going a slightly different route. I'm using the injectors from an r3 rx8. These work like a fuel injectors but have oil pressure behind them. I've tapped the front Iron right above the power steering pump for the oil feed.
