Reflashing the computer?

[MamaLion1]

In anther thread I was discussing certain problems with ignition and start.A mention of possibilty of reflashing the computer. What exactly is that, and how much and how long does than usually take. I spent 549.00 to have a new Idle Air Control meter put on last Friday.The Mechanic(not at Infiniti dealership) assured me this would solve the problem. The car was actually worse after that and wouldn't crank. I had to have it towed back to mechanic.They worked on it several hours without being able to determine the problem.

A reflash is when the dealer flashes the ECU to the latest callibrations available from the manufacturer. It normally takes up to 1 hour.
