I always thought the PCM monitored oil pressure as well. While it might not cause performance issues, it would most certainly throw a code and subsequent SES light.

If you look at a 6L water pump, this is the outlet and the front is smooth. It's offset slightly so as not to interfere with the throttle cable

If you look close behind the spark plug wire, you will see the braided line I described above.

Again, this is different than a stock "cover". What you see is an adaptor where I can take oil and send it to a cooler. See the 2 big AN fittings? The brass adaptor and the 90* AN fitting comes off where a Vette's oil temp sender would be.

HTH

Let me give credit, where credit is due ... I got this from Glenn98ZM6

Well maybe I'm wrong... but I can't monitor it with autotap (although my version's pretty old), and at least for 2000 the PCM pinout does not have a connection for oil pressure. (Maybe later years were different?)

I dunno. I dont think its real accurate either but what is, my spedometer is off and so is my rpm, and so is my water temp and probably my oil pressure to

So, does anybody know on the GTO LS1's will you cause codes or tuning issues w/ the PCM if you replace the stock sending unit with one that leads to an actual gage?
TIA,
Dan

I asked my tuner about this the other day. His answer was that the PCM does not see oil pressure.
He said that there may be a Soccer Mom protection that will kill the fuel pump if there is no oil pressure.
I am going to unplug my sensor and see if the car will run.

Be back in a few

I was under the impression that the stock oil pressure gauge was a good indicator of oil pressure?

I have an electric oil temperature gauge that seems to work well. I drilled/tapped into the fitting above the oil filter.

Well, us GTO owners are lucky enough to not get a stock oil pressure gage - isn't that ridiculous...

Haha yeah it is but no more rediculous then a dummy gauge that is in the 2000 cluster.

Are you saying the oil pressure gauge that is in the 2000 f-bods are dummy gauges? Mine seems to work just fine. After the LS6 pump was installed, I got a lot more pressure on the gauge - it not idles right at 60psi, and it used to idle around 45-50psi before the new oil pump.

Dummy gauge is normally associated with the temp.. but the oil pressure seems to work good enough for me

PCM does not see the Oil Pressure for any Fbody. There is no fuel pump kill switch either for oil pressure in the Fbod's. The car will run just fine without the sensor hooked up. All the sensor does is go straight to your gauges. And it is not a dummy gauge either as somebody else mentioned. HP Tuners cant read your oil pressure either.

I installed an Autometer electric oil pressure gauge and tapped the plate above the oil filter for the connection. What I found was that the factory gauge is not an idiot gauge (like the one on the 95 Mustangs!). However, it is not all that accurate either.

My factory gauge reads approximately 10 psig higher than what my Autometer reads. I had a mechanical Autometer sitting around and hooked that up just to compare it to the electrical gauge, and they read the same.

At hot idle, my factory gauge reads a tick over 40 psig....my Autometer reads about 28 to 30 psig.

If you want to keep the factory pressure gauge and or sender, then make a T. Get a section of -4AN braided steel line, run it from the block with the proper adapter. Then on the other end, install a T fitting and run both senders off of the T. With the line extending from the block, then you can put the sender anywhere you want, or have any size you want. Problem solved.

Stock or modified LS6 pump?
You put it in yourself?
