I'm sorry, I don't. My aftermarket gauge does not have an aux output. The OEM oil pressure sensor is very accurate (compared with the aftermarket unit; they are always showing the same values), but I know from the Corvette world that the refresh rate will not be sufficient to catch any oil starvation issues. Back in the day, when LS7 engines died prematurely at some of the tracks, someone had to use an auxiliary oil pressure sensor to log the momentary loss of oil pressure in some of the the long left sweeper corners. The fluctuation was only visible with high frequency reading, while the OEM sensor readings did not reflect the drop in pressure. In the end, GM upgraded the dry sump, increasing its capacity to 10.5 quarts, and the problem was solved, at least for the most cases.
Long story short, if you really want to dig in, you'd need high frequency readings, and I'd not rely on OBD II readings. By the way, before you discount an improved oil baffling, please keep in mind Camaros come with better sumps than Corvettes (since the engines are mounted higher), and baffling is more effective than what would be the case on a Corvette. What's more, some of the new V-series Cadillacs come with improved baffling from the factory, and GM suggested they're good for 2 Gs. Oh well, we'll see.
