i just put a 96 motor in my 1990 miata, i have a flyin Miata turbo kit and im running it with a 90-93 megasquirt. It starts and roughtly idles, but far from complete.

my problem is that when idling, there is a small buzzing sound from the IAC. What does a bad IAC sound like? I modified theECUTPS sensor,and calibrated itfrom 112-212. Can anyone comfrim thatis correct. http://www.miataturbo.net/showthread.php?t=36271

Also, what setting do i need to changegoing from 1.6 to 1.8?

MAGASQUIRT

The buzzing is more than likely the IAC as you suspect. There should be some articles on servicing it on miata.net. As far as your MAGASQOOGEs vTPS, those numbers will probably differ depending on the sensor you have. You didn't say which Megasquirt you have, so I can't really help you much past that.
