Shocked by your findings on AMS oil pan: I got mine specifically to eliminate concern on track, and you saw it dropping pressure even sooner than OEM Pan.
You say it dropped oil pressure sooner but not as low: can you kindly tell us how low did it drop?
Anything else you can add?
I am not all that happy to rely on Accusump when oil pan design is inadequate.
May have to take it off, and find DIY solution.

I still need to upgrade to the electric switch. 2qt system should be enough. 2qts is more oil than most pans will offer. I plumbed mine right into the oil filter housing.
I personally don't have any data on other pans, but I've been told from a few sources now that the drops still occur with the AMS pan.
I've concluded the Accusump is the best fix.

Are there any oiling system diagrams available to make a good determination of how/where to install the Accusump? I would be concerned about the flow direction of the oil coming from the Accusump during a low oil pressure situation (Accusump recommends using a check valve). Looking at some google image search oiling diagrams, the best way to ensure the oil from the Accusump is going towards the engine is to connect it at the oil cooler return line with a check valve that prevents back flowing the oil cooler. Mitsubishi manual shows the return line as the one connected to the bottom of the oil cooler which seems backwards.
Nevermind... reading Accusump's instructions it says the check valve isn't necessary as it isn't likely that oil will be able to travel back through the oil pump. So, it doesn't really matter a whole lot how it is plumbed in.

What did you pre-charge the air side of the Accusump to?

the only thing that really matters is the end result. This can be seen when logging. I can 100% say my result is better than no accusump. Is it perfect yet? no. I'm still using the manual valve. I hope to try the electric valve and test again.

according to instagram, that hardcore orange time attack evo that john carson drives in GTA will be running this pan this year...so should have some heavy duty testing.

Using the electric valve, the accusump will fill slowly until the pressure threshold is reached at which time it will rapid fill.

Much better then even I hoped for.
Conditions: Fair/80deg
Track temp: 93deg
Setup: ST2 map, Fresh R7's, remembering how to drive stick again
Summary: So being it's been forever since I've been given a brake from the house project I wasn't at my best but my focus was mostly on getting ya'll this data and remembering what I needed to remember for next time. I was way outclassed in ST2 but I had fun none the less and placed 3rd.
So here's the output from that run:
Ignore those first dips, that's traffic bunching up after a hot lap and me having to come to a stop almost before the green flag.
What it doesn't say....is that we forgot to tighten the oil cap after refilling it from a new catch can setup thats sucking oil from the dipstick (another post). Thus, this pan KEPT optimal PSI even though 2 quarts of oil managed to escape all over the engine bay (yes, I'm still finding oil from when the dipstick let go, and now this lol). I'm convinced it saved my motor this round. And no, no leaks from the pan still

Well then. My only issue now is it won't clear my O2 dump.
