Thread: Oil pressure safety shutdown.

  1. #1

    Default Oil pressure safety shutdown.

    Hi all. I know this has probably been asked and covered before, but I can't seem to find an answer that will suit my application

    I have an oil pressure sensor installed and would like it to cut the fuel flow/kill the injectors when the oil pressure drops below say 5-10 psi for more than a few seconds or so.

    I've read posts in regards to cutting ignition or rev limiters, but as I'm not running any timing control I can't use this function
    I also read some posts about triggering the fuel pump to turn off and the general consensus was to not do that as it would lean out, as the fuel pressure starts dropping.

    Is there a way to do this or is it only limited to ignition cuts, etc.? Thanks In advance.

    Generally speaking, I do not like the idea of the ECU shutting the engine off, because this could lead to a potentially dangerous situation while driving.

    If you're worried about saving the engine in case of low oil pressure, I suggest creating a warning output and having a light go off in case of oil pressure dropping. This way you have notice and can shut the engine off yourself. Andrew
