iat sensor relocation?! help!

Okay, so putting a paxton kit on soon.

fla is so hot this time of year so wanting to add meth to cool things down a bit, to keep it from pulling timing. to do so i need to relocate the IAT sensor since i cant spray the maf with meth.

Anyone know the wires to cut on the maf and what sensor to get to do so? is the slot maf the same as the 2010? pins 1&2 are the iat on those and can easily get a relocation kit for that if everything is the same.

thanks
Scott

Yes, if you are spraying methanol you need to do so AFTER the mass air meter unless you want to spray before the head unit, which a lot of injection companies suggest. I do suggest relocating the IAT sensor to the intake manifold.

Without walking in the shop to look at a car, take a look at his. Just go based on the PIN locations, not the colors. The pre 2011 used a different connector that has now been changed to the one that comes with the 2011's

So can I just a sensor made for the 07-11 gt500 or the 2010 relocation sensor? I would think the voltage return is the same. The nag itself changed but doubt the iat sensor voltage did.

Was going to spray after the maf before the tb with the sensor relocated right after that almost at the tb.

Here are the part #'s for a 2 wire Lightning sensor and connector.

This is for the NON Threaded.

IAT sensor F57Z-12A697-A

Pigtail/connector kit 3U2Z-14S411-JZA

For the Threaded (what I am using), here are the 2 part #'s. Due to pressure in the tube, the threaded would probably be better.

3U2Z-14S411-JUA

9C1Z-12A697-B

Lightning threaded sensor.

You will actually need to split one of the 2 wires (it will go to the sensor and maf). I can't remember off the top of my head which ones, but you have to split it or the maf will go into default mode.

Thanks for the help and part #s, member on other forum said the blue is the common between the maf and sensor. So going to tap the blue and run the violet/gray to the new sensor. Hope it works so I can get these IATs down and octane up.

Its a shame that that is for the 05-10 Mustangs. The 2011 5.0 is a frequency based MAF, so there is only 4 wires, 2 for actual MAF, and 2 for IAT.

Of course, you could just wire into the IAT2 input on the ECU so you have a before and after like the Shelbys (if your tuner can turn that input on).

Ummmm, more info please?

Is that possible cause id love to do that and not hack my maf up. Then I just try mixtures and see what works for me.

The 2011 MAF is one wire for +12v, one for MAF signal, one for IAT signal and once common for both IAT and MAF.

The Roush kit has you wire the IAT like the GT500's 2nd IAT sensor. But it appears only FRPP and the Roush tune can actually use it, not sure what they are doing to use it but since they dont do a tune for an auto car I just had to replace the IAT in the MAF with the downstream sensor.

I can turn the 2nd IAT 'on' in the tune but I cant find a separate table for it or anywhere to monitor it so who knows if it actually does anything with the auto ECU. Might be some tables in there I cant see with PRP software though.

Here is the 2011 MAF wiring from the service manual:

The hardware side of things is easy, tie one side of your new IAT sensor to pin 36 of the bottom ECU connector, and the other side ties into the wire at pin 56 of the same connector.

As to the tuning, thats up to you and your tuner. I know that we use the IAT2 setup on all the 5.0 cars, from Whipple, Roush, KB, whatever, whether its auto or manual.

Using the IAT2 option is optimal for cold-start conditions. This is why FRPP does this because it is important to also have the ambient sensor

I'll talk to my tuner, more then likely I'll be just tapping the blue wire and rerouting the violet to move the iat for ease.

Plenty of cars only run 1 sensor, as long as the meth gets a chance to hit it, it should be good to go and accomplish what I need. especially if iat2 won't have an affect on PCM adjustments. Seems like the car uses iat1 for that.

Good info.

Unless that's just the prp that can't change it to iat2 for PCM adjustments.

thats how i've been doing it, don't have meth or anything on it, but works perfect for actual iats pre intake

You need to make changes to run the IAT2 sensor and wire it in properly if you want to do it right. We do the same on all our kits will be doing it on a Raptor shortly

you use iat2 or just run the single like beef?

The switch is there to enable IAT2 on the PRP, and it may in fact do something. But I couldnt find a way to log IAT2 and I dont see a table to adjust I dont know if its doint anything or not when enabled so I just replaced the MAF IAT with the downsream.

Honestly the single sensor downstream works just fine for me so I really havent looked that much into it. Like I said the roush instructions show what pins to use for IAT2 so obviously they use it that way,

We use it like the FRPP/Roush instructions using IAT2.
