Question Oil Pressure Proposal??

HI I come from Taiwan my car is 94 Mx-5 1800

Recently found my Oil Pressure
850rpm is 1.5kg/cm2
3000rpm is 3.0kg/cm2
6000rpm up 3.5kg/cm2

This is normal?

If high rpm driving 5-10 minutes I heard HAL TICK

3000rpm is 3.0kg/cm2 = 42.7psi
6000rpm up 3.5kg/cm2 = 49.7psi

I have always gone by 10psi of oil pressure for every 1000rpms.

Yeah that is a common view.

Its silly as I am sure all engine designs vary, but thats seems to be common consensus.

I exchanged Japan ECU 8000rmp off oil
So 10 x 8 psi = 80psi = 5.6 kg/cm2
Evidently my Oil Pressure not enough

For a warm engine I find it hard to imagine that it will be 80psi... I'm trying to think back to when I had my oil pressure gauge, and what my pressure was, but it definitely wasn't 80psi. Maybe 60psi at higher rpms.

Oil has a relief valve so it doesn't just continue rising. For my '99, Miata Shop Manual suggests 43-56 psi at sensor port at 3000 RPM.
