Oil pressure cut off feature on std ECU

[AndyF]

Anyone have an electronic oil pressure gauge with a 0-5V output that they could hook up to an ECU input and do some datalogging to get some values for me please?

I fancy writing some new code for a low oil pressure cut off feature.

I have a sensor you can borrow if you like 0-5v, just make sure you set a minimum rpm pressure otherwise you could end up with it cutting the engine at idle.

It would be worth testing various oil pressures on cars using different viscosity oils too.

Would be good if you could set it up to work on throttle v pressure so if you are flat out and it drops oil pressure the engine will cut :)

I think RPM vs oil pressure table would be far more useful. TPS or engine load has no relation to oil pressure. Just RPM and oil temp.

I have Greddy gauge where I can get at least alarm out. To me it would be good enough to have on/off input with adjustable polarity and lower RPM limit that could be used to cut off the engine. Especially as Evo 5 ecu doesn't have spare A/D converter inputs...

Andy did you get any where with this mate ?

this would be a great feature for any ecu
