    First off your ECT readings are very high 230-241*. If you just did a cam swap or coolant swap, you may still have some trapped air, if not, you might want to give it some attention.

    Since you are in open loop, your commanded hi res PID is referencing your OLFA table. In that table you are commanding 1.12 to 1.13 in that corresponding area(MAP vs. temp). This is why for tuning purposes especially if using open loop, it is suggested that the area from 140F to 284F be set to 1.0 to be at 14.7/1.0=14.7.
    In your case, it would be 14.62/1.0 = 14.62 which is acceptable.
