Right? Takes discipline and practice to work a regular sweep of the gauges into one's routine. Those stupid little lights are worthless.

Many gauges have a warning function that you can set to whatever pressure you want. It's really worth paying a little extra to have that. For it to be useful it might need to be set where it is going off at idle though.

The older pressure switch came on at like 2.1 psi, which is essentially useless. The BRZ appears to also just use a warning switch and does not monitor actual pressure, for the dash warning light anyway. Seems like there may be an avcs/avls related oil pressure reading?

So yeah, pull that out and use the plug for the sensor. Keep in mind that a lot of gauges that use PSI for units use an NPT fitting while the stock sender is BSPT/PT. Prosport and Killer B make galley plug adapters that are NPT.

That's my resistance to just getting a gauge, I'm not going to check it while on track.

The longacher (accutech) SMI gauge has 3 stage alert plus wiring for an external light. Seems like it might be win-win

I like @Lunatic's bright light solution.

It's hard to check gauges when on the track. I had a gauge but also the 2" led light that would light up the sky if it came on.

iirc the OE sensor does read an actual number, wouldn't it be possible to get that number via OBD2 port, display it on a phone/tablet/AIM laptimer and write a warning light calculation/threshold having to do with psi/rpm? (20 psi at idle is cool, 20 psi at 6k rpm no bueno)

Best of all worlds, no tampering with OE sensors, a real gauge and logging actual numbers, and a dummy light that's actually useful so you're not distracting yourself on track.

Nope. It's just a switch.

:bonk:

Was thinking of oil temp being readable via OBD port, my mistake.

But, still possible to write a dummy light if you're running data logging capable of it.

Defi gauges have a buzzer when water/oil temp too high or oil pressure too low. You can set when it goes off

The defi standalone racer gauges do not have a warning- you need the advance link system for that. Aem X-series, prosport premium, and the upcoming greddy gauges have warnings off the top of my head.

AEM's failsafe wbo2 does a cool thing where it develops a safe curve of RPM, boost, and AFR, and then if the readings fall out of that range it cuts boost or switches maps or whatever. Having something similar that was oil pressure vs rpm based, possibly with a temp compensation would be handy. A few ECUs will do something like that actually.

Yea the advance BF series it what I was referring to. They also record up to 3 minutes and can view peak hi/low. The buzzer is decently loud too, unless you mount the box somewhere where it will be hard it hear. Only downfall is the box, it's not that big though.
