2G Oil pressure sensor wiring

[tschuhly]

When installing my aftermarket oil pressure sensor, should I splice it into the ECU (with ECMLink)? It doesn't look like there is a dedicated pin from factory for this so I'm wondering what I should do?

You/we have limited 5 volt options. You need to use one of the inputs listed here: https://www.ecmtuning.com/wiki/externalsensorinput
Be mindful that the baro input may require modification depending on your sensor.

Do you think it's worth it though to log oil pressure or should I save the limited spots for something else? So far I have oil psi, boost, afr.

That entirely depends on your needs. For a street car, probably not. A gauge with a peak recall capability is usually enough, like AEM X-Series.
I'd personally sooner log fuel pressure before oil pressure for a street car.

You can use same sensor ( maybe) if its a 5v sensor to log fuel pressure.This is a better use of a log .

For something like oil pressure which is a lill more important to monitor live, use a gauge.

Looking back at a log of low oil pressure doesn’t do much when you have a starved/scared or seized engine.

But you can more likely survive a fuel pressure drop depending on a circumstance.

To clarify, your saying that I should log oil psi over fuel psi?

Right now I just have a fuel gauge on my AFPR.

Oh sorry I just reread it and I gotcha now. Your saying that it wouldn't really make sense to log oil pressure because it should be constant and if you don't have it, then it you can't exactly run a log to begin with because you'll break the engine if it's not broken already.

Whereas fuel pressure is something that can fluctuate based on setting and stuff.

100%
Use your 4 availible pinouts wisely. Oil is important but a real gauge is good enough. The dash gauge is basically a dummy

oil pressure is not constant by any stretch of the imagination, but keeping tabs is easy with a gauge. a peak-style/recall feature is handy to know your max when your eyes should be the road.
