Weird problem on a stock 2011 Z06 Carbon: The engine cooling fan comes on when A/C pressure climbs into the range found in the fan control chart in the tune file. And I can turn on / control the percentage of speed for the engine cooling fan with the bi-directional controls in my scanner. But engine temperature alone will not turn on the engine cooling fan. Temperature displayed on the scanner matches the temp indicated on the DIC. And the scanner / DIC temp closely approximates the analog gauge. Has anyone seen this? Any thoughts for a solution?
