Help!!!

[MX-5_Fast]

Hi, i just got one of those resistors that go in the IAT sensor, but i can't find the IAT. i thought it should be somewhere arround the intake, but they said that if it has more than two wires thats not it. so i found another little sensor just under the throttle body, a little green thing, behind a black round thing, i just want to know wheres the IAT sensor, i got a 97 MX-5. i would really apreciate if you have a picture, thank you!!!

Throw that resistor away. It does nothing but dump more fuel into the engine. The Miata already operates richer than would be desired.

But if you really must know, I think it's built into the MAF (not exactly sure on the OBDII models).

eBay deal? Worthless...

Best thing is to find a buddy with a 12mm wrench, timing light and a paper clip. Now advance your timing a little. You probably will have to go up in octane level depending on how far you advance the timing.

Off the Miata.net page:
Extra power by advancing
Most Miata engines can benefit from advancing the ignition timing. How far you can safely advance the timing will depend on several factors. One major factor is fuel octane. The higher the octane you are willing to buy, the more timing advance you will be able to run. Ambient temperature also plays a role--the hotter the weather, the less timing your engine will tolerate. Different Miatas also have their own idiosyncrasies about timing. As engines pile on the miles they develop an octane appetite from carbon deposits in the combustion chamber which can cause hot spots and actually raise the compression ratio of the engine by reducing the size of the combustion chamber.

Many enthusiasts have found that they gain a few extra horsepower by advancing the timing to 14 BTDC. Some have gone as high as 18 BTDC without problem. The difference between going from the stock 10 to 14 is much more noticeable than going from 14 to 18. Ping is usually experienced under hard load driving - not idling in your driveway. So you'll have to set the timing and drive it for awhile before you really know the effects.
