Another update with the most recent data from AMP with PCA this last Saturday.
It was a spectacular day to be at the track, great weather, air temp 65-70F, only a few cars in DE4, so a lot of open track!
Here's a link to the first 15 minutes of session 3, with data overlay showing the oil and accusump pressures. I had the by-pass switch turned ON for this session. This basically bypassed the pressure switch and kept the solenoid valve open.

Here's the updated data summary that includes the 4 sessions last Saturday:
Something went wrong for session 2 as indicated by negative pressures.
The oil pressure during session 3 was rock solid. I am sold on the Accusump by-pass mod. I think this is a configuration that can be used for pre-oiling as well as open valve for track usage. I also believe the 15 psi Accusump air side preload is more effective than the recommended 7-10 psi. One other thing I'm doing is keeping the oil level slightly above the max line on both the dip stick and the electronic gauge. No issues with AOS.
