Intake air temp sensor location?

Intake air temp sensor location?
Does it matter if the sensor is located in the stock cold air funnel when using a Frankencar intake? Car runs very strong, seems fine. On the stock box the IATS is located well before the MAF. On the Franken, it is located just after the MAF, seems I may be getting a better reading having it located in the stock location and is where it is located.

You can stick it on to of the battery and nothing will go wrong. Just make sure you plug up the hole though. The sound is too high pitched and it doesn't growl the same way as a pluged up one.

does anyone have a fsm that might shed some light on whether the sensor controls any settings?

From the FSM:
The intake air temperature sensor is mounted to the air duct housing. The sensor detects intake air temperature and transmits a signal to the ECM. The temperature sensing unit uses a thermistor which is sensitive to the change in temperature. Electrical resistance of the thermistor decreases in response to the temperature rise.
On Board Diagnosis Logic
Malfunction is detected when
(Malfunction A) an excessively low or high voltage from the sensor is sent to ECM,
(Malfunction B) rationally incorrect voltage from the sensor is sent to ECM, compared with the voltage signal from engine coolant temperature sensor.

I left it in the stock location as that is as close to stock location as possible (before the MAF getting cooler air).

So based off this would you keep the sensor in it's stock location when used with a Frankencar or would you put it in the Franken location of after the MAF?
