[quote name='Comitatus' date='Jul 5 2005, 08:57 AM']Ok, so the only sensor that I can get, that I won't have to tap, would be the Mazda one?
Will I be able to use the Mazda sensor with a Haltech?

PM 94Touring...He bought a used one but never needed it. So it's just sitting there...You should be able to get that one cheap.
I hear of quite a few people relocating the AITS (Air Intake ThermoSensor) to the elbow...Mainly because the UIM will get heatsoaked and heat the sensor...Something about the AITS thinking it's seeing hot air because it's heat soaked and then getting a rush of cold air or something like this......
Carson, can you clarify?

the GM sensor is superior to the 1993 Mazda one...I would use an upgraded sensor with Haltech, I know I would (did).
if you've seen a Mazda temp sensor side by side with the GM one...there is no choice (with upgraded ECU). The Mazda sensor is slow reacting because it's in a "tube" that is molded to the thread base...so yes it gets heat soaked and can't handle...say WI as well or as safe (maybe?!?) The GM sensor has a "cage" around the sensor element that allow air to move thru the sensor without the temperature of the house or UIM affecting it (as much...I'm sure there is someone who could argue the heat of the "cage" radiates heat, therefore the sensor picks it up)
don't be afraid to drill your UIM and then run a tap into it...fawk your about to rewire your car, haha!

Is upgrading the sensor to the GM one easy as plug and play...Except for tapping? Or is there some software configuration that needs to be done with the ecu?

Anyone know the part # for the Generic GM Sensor? I have been to a few auto parts stores, with no luck.
Should I drill and tap in the stock location or would somewhere else give a better reading, as stated above?

they are all the same, but theres a bunch of different part numbers. problem is they are all cataloged by application.
i went to pep boys and started listing applications until we ran across one they had, happened to be for a zr1 corvette of all things

Dave - you will have to splice in the GM connector also. No software configure...it just gives a resistance. I don't know anyone running one with the PFC however?!?
Comitatus - I see no problems with the stock location and this sensor. I went to NAPA and asked for a GM coolant sensor (when my connector broke) and they were able to pull one up, no problem.

So the coolant sensor can be used as an Air Intake sensor as well? I didnt know that...learn something new everyday I guess.
That's proabably what the problem is, I keep trying to locate the Air Charge Temperature Sensor, with no luck.
What is the threading size? 3/8 NPT?
I'll check the store tomorrow.
