MAF Voltage at Idle

Set up my Profec to measure MAF volatge, so I can try to get estimates for TP expansion on mapping.

Problem is, mine seems to run around 1.1v at idle and I'm sure I read somewhere the spec was ~0.5v! Anyone enlighten me?

I'll double check it through the week with a voltmeter, but there's no reason to assume it's not accurate.

    OK, hooked my AFC up today and it's around 0.5V with ignition on, engine off, and around 1.1V at idle.
