interesting, I will need to wrap my head around engine rpm vs pump rpm vs pressure output of a pump to respond more intelligently.The variable displacement oil pump doesn’t run lower than normal oil pressure at idle. The variability is to allow for higher pressures at under high load, low RPM conditions.
I originally viewed the purpose of the variable displacement pump was to help with fuel economy, as in can run lower pressures at lower load for instance independent of engine rpm.
So is it electrically controlled?
Either way, my intent was an added variable. From the point of it isn’t that variable displacement oil pumps are bad, but rather to the effect that a certain batch of them could be “faulty” and I hate that word for what it is worth.
