IAT Gauge

[Tommy Gun]

I would like to add an IAT guage to my track car. Perhaps a sensor just before the TB.

I had heard of people using a factory sensor to gauge from.

Does anyone know of a factory sensor I could use? I don't know where factory IAT sensors would even be or if perhaps a different sensor can be used for this purpose?

This would be on the 2002 Mustang .

The sensor should be in the intake tube (rubber). That's where they were on the '94-95's.

Are you saying that there is already one on my car?

I'm talking about a 2002 Mustang.

I'm almost positive there is one. Is there a sensor in the black tube after the MAF meter? The computer uses it to determine A/F ratio to prevent detonation. Look for a black sensor after your MAF meter on the intake tubing (before the TB).

Thanks, I'll have to check.

I have added a Centrifugal S/C and CAI so things are different.

If there is one, I wonder how I can add a gauge to it?

That would depend on how the signal is sent to the computer. If it's a straight voltage there may be a gauge that can convert that voltage to a gauge display. If not you could add a sensor at a different location in the intake track.

Do 02's have an OBD port? If so, isn't IAT2 read there (or is that not a reliable reading?). If so, I might be able to assist with an Interceptor Gauge if I end up not using it. I know I can read IAT2's off the OBD port (I've played around with the Interceptor gauges a little)

[Tommy Gun]

Okay, now this is getting too deep for me.

I'm outta here....

The '02's do have an OBD-II port and the reading on the port will be in degrees Fahrenheit. You would need a gauge (like the interceptor) that could display the OBD-II data.

Why are we talking O2's?

That won't tell me IAT's?

:haha:

No but they will tell you A/F ratio which is in part determined by IAT's. So I'm sure that you may be able to deduce your IAT from you A/F ratio. I heard your good like that. :haha:

[Tommy Gun]

I'm looking to reduce IAT w/ methanol injection. :hiding: hence I would like to be able to read IAT's.

Looking for an easy way to do this.

Dufus. 2002. Read up on the Interceptor gauge. http://www.aeroforcetech.com/products_interceptor.html

As I read up though, the 94-02 mustangs require the FD series, which I don't have, while the 05+ require the CNF which I do have. But maybe this will give you some ideas.

Interceptor gauge. Read it. Easy peasy. Plug into OBD port, run wire to whereever you are gonna mount the gauge, happy reading. $249 I think. You can buy different sensor kits if you want other readings too (wideband, oil pressure, fuel pressure, etc).

Probably a gauge that you mount to your OBD-II port. This would also allow you to monitor other data if necessary.

Another option (maybe)... do the GT500 MAFs run a 4 wire or a 6 wire plug ? If it is like my SCT BA2400, the MAF has what looks like a resistor hanging to the side of the air flow sensor elements. My car (04 cobra) only uses 4 wires of the connection, so that resistor is actually doing nothing. What it really is, is an IAT sensor. Just need to get the wiring information for the other 2 connectors on the plug, and you should be good to go.

Note: My STOCK MAF does NOT have a "resistor" in that area... so maybe it is only an aftermarket thing... not sure, but something to look into anyway.

What you really want to monitor is the IAT in the manifold not before the TB. That is the air temp just before it enters the combustion chamber. That is the temp you probably want to measure when you spray methonal into the air stream.

Most engines have an IAT sensor located in the intake manifold on one of the intake runners. ( you'll have to check to see where yours is)

Most data loggers that connect to your OBD port can monitor the IAT temps taken from that sensor.

Remember if you decide to use methonal injection to get the most out of it you will need to add timing and reduce the amount of fuel the more you add the methonal.

To do this effectively the most important thing you will need to monitor is the A/F ratio using a wide band o2 sensor . That is the most improtant thing you will want to know not necessarily the IAT temps.

I have a friend who had his set up where they didn't change the tune much. Reason being, if the methanol injection stops working for some reason (like the pump stops working) then he won't end up running lean and burning up something.

I think that is how he explained it?

I may not do this because I don't know enough about it.

With your luck, that's probably a good idea. :yes:

[Tommy Gun]

It is supposed to keep the car running much cooler though.
