Hey all, I noticed my air temperature sensor was just hanging there and the intake that came with the car looked like it had been hit with an axe :( anyways bought an AEM V2 kit to sort both probs, however there isnt a place for the ATS on it? What have other people done with theres? or is there another place to put it?
Any help appreciated cheers :nice:
 
Drill a hole in induction pipe then get a rubber grommet of appropriate size to fit hole and drill a hole in center of grommet big enough that you can slide the IAT sensor into it.
 
As above :) is what engine is it? As the ek9 doesn't have IAT sensor so if you bought it for and ek9 and yours is an ek4 it won't have the hole for the sensor as they use different looms :)
 
Ahh makes sense. Its an ek4 with a b16b conversion, hense its not in use. Hmm should i remove it or drill a hole?
Cheers for the replies :)
 
The EK9 does have a IAT sensor it's located on intake manifold rather than in the induction pipe like ek4. You can extend wiring to reach it and i'm almost sure the plug you have on ek4 loom will fit the sensor

Thanks for that mate, I'll have a look and see if I can get it to fit, if not I'll find a way!
 
Is there any difference between using an IAT sensor at the inlet pipe vs. intake manifold IAT; #2 runner?

I would imagine that having the IAT sensor on the intake manifold would reflect higher temps due to the intake manifold absorbing heat from the engine bay and transferring it on to the incoming air.
...i think i just answered my question...it would be more accurate with it being on the intake manifold, wouldn't it?

Yes the temp readings are higher with the IAT sensor located in the I.M rather than air pipe but it doesn't really matter anyway as the ecu has IAT lookup tables for different air temps it sees and can apply correction to fuelling as needed and in the case of the IAT located on I.M for the type r engines it would have been calibrated for that.

Thank you Vtec6000.
... I guess I should be using the sensor on the intake manifold and not the inlet pipe if I am running a type r motor especially if this is how the type r's maps are calibrated. Currently I am running the sensor at the inlet pipe...

I wouldn't move it now as you have had your car mapped and the tuner would have setup the IAT lookup table in accordance to the air temps seen by sensor in intake pipe. IMO the readings from IAT in inlet pipe is a better reflection of the air temp entering engine and tend to get less swings in temps especially at idle or driving slow i.e caught in traffic where the I.M is getting very heat soaked.

...thank you again Vtec6000. :nice:
