IAT sensor in the flo meter? Also I have Hawk black pads on rear after two events they have

I don't know what IAT is referring to, but the Miata Enthusiast's Shop Manual shows this:

It's definitely worth picking up a copy of this book if you're going to do any work on a Miata.

I've never used the Hawk blacks, but years ago my old Axxis pads (street/light track pads) did this. It's a result of overheating. Since going to more aggressive pads (I'm using Carbotechs now), my pads don't do this any more.

Hi Barry,

I have been running hawk blacks for years and that is pretty normal. They do look nasty when they first bed in, but they end up seating nicely and last a long time. I have nearly 40 track days on the rears on my car.

How has your car been doing at beach ridge?

Intake Air Thermo sensor is the Red/Green wire THAA. The sensor is integral to the airflow meter.

I've had Hawk Blacks crumble.

I've used Hawk Blues. They also crumble.

I solved the crumbling problem by switching to Carbotech pads. Both are great pads. Slightly different pedal feel and initial bite. Barry, if you are interested in Carbotechs for your 1.6 Miata, I would recommend XP10 front, XP8 rear.

Here's some info on the IAT:
