I've recently rebuilt my motor entirely (forged bottom end, etc) and added an oil pressure sensor. I'm looking to add oil pressure failsafes to my MS3 so I logged a long drive (largely highway miles) and then viewed an RPM vs Oil Pressure vs TPS graph as shown here:


I am not highly familiar with the complex details of engine oiling. However, I would expect to see something more... linear? There appears to be multiple lines of best fit, so there must be something in common. Oil temp, duh. So next I charted my RPM and Oil Pressure against my new Oil Temp sensor:

That looks much better! This is a pretty wide range of oil pressures vs temperature though -- at idle it is anywhere from 20 to 65 PSI. My concern here is that my "safe range" would have to be very wide -- wide enough to include oil pressures that I would consider unsafe depending on temperature. This is the min/max oil pressure table that I came up with based on the above graphs:

Ideally this would be a three-axis table with the additional axis being temp (ideally oil but coolant would be okay as well). Is there any way to do this or at least add a "trigger" wherein the oil pressure light only activates above a certain temp, or do I just have to live with these wide bins?
