Crash - I think I may have found the answer to this. I was talking to the guy building the harness for my son's truck and he told me you can go into the tune and turn this feature on. Here's a screenshot of where you go in HPTuners. Go to system, and select the options tab. Then add a 1 in the oil pressure column. Let me know if it works.
