12-2-18 - oil pressure mechanical limit - When I prime my engine with oil pressure from the Accusump prior to cranking the car throws a plausibility code for "engine oil pressure too high before cranking." This plausibility code seems to force oil pressure to run at the mechanical limit with all bypasses shut. This log was of off-throttle deceleration to show how oil pressure behaves when the car is throwing the plausibility code. I am still seeing over 60psi oil pressure down to 1300rpm while being completely off the throttle. This seems to be significantly higher than what was being achieved by modifying the oil pressure table set points to 60psi+ at the same rpm.
