IAT Wire off ECM?

[azpyroguy]

Does anyone know what wire off the ECM I can tap into to get the IAT (Intake Air Temp?) I want to put a gauge so that I can see the effieciency of the heat exchanger.

Your gonna wanna try to keep that temp BELOW 120 deg far.....at that point the PCM goes haywire dumping fuel and pulling timing. The VEC3 programming deals with this.

Do you know which wire that I can tap into to and connect to a gauge. If I have to I can drill and grommet a port in the intake tube... but would prefer not to.

I'd also be curious as to how to do this.

The IAT signal circuit is located at terminal 15 of the black C1 PCM connector - dark blue with light green tracer.

Because I could not find a gauge that supported the OEM sensor I ended up getting a AutoMeter UltraLight Intake Air Temp kit, after installing it, and taking the truck for a test run 30-45 minutes... getting the engine, supercharger, etc.. all good and hot... and the outside air temp being around 60 degrees (or so), the air temps stay at 75-80 degrees, when sitting and idleling for long periods they go upwards of 140, but the minute I start moving air through the heat exchanger (Boomers), temps drop right back down to 75-80 range.

Now I know that in our AZ summer they will be probably around 100 or so... but giving that the system can cool off the hot air as it.. I think its going to be really efficient.

Hey Bro,

I was wondering how does Boomers kit differ from the stock version?I bought my Paxton kit from our good buddy VPRPWR and he gave me an aftermarket heat exchanger that is used on the ford Cobras.Its bigger and I wonder if it is an improvement since I never put on the Paxton stocker to compare.
Do you lose any power after your engine is at max temp.(200 deg.) ?
Just curious.Thanks! Bill

Boomers kit is a auxillary kit to the existing heat exchanger sytem that came with the paxton.

The kit does not lower engine operating temps.. thats up to you adding more fans (such as Boomers cooling fan kit).

But the kit does lower the air temps going into the motor which tells the PCM to raise or lower timing.

You want to keep your temps as low as possible... preferably lower than 120-125 anything higher than that and the PCM starts to pull timing out thus making a power loss.

If your operating temp (water temp), goes above 205 degrees, the PCM also pulls timing out there as well, again resulting in loss of power.

Both are to prevent (or minimalize) detonation.

If you goto Paxtons website, they have my truck featured in the "gallery" page which clearly shows Boomers heat exchanger kit on the front of the truck.

Thanks! I had asked Boomer if he would sell it to me,but he said I would have to buy the whole Paxton kit in order to get it.

Thats nice of him.:dontknow:

I am not sure why he wont sell you the heat exchanger by itself... he offers it as a option on the kits (at least he did for me...).

Even at that... any water heat exchanger that you replace the stock Paxton one (which is just a cheap SeKalb Oil Cooler), will give you noticable gains.

I dont care the kind that require you to route your air intakes through them... I feel they have massive loss in boost...

Once boomer is out of hospital I will ask him why he wont sell you just the upgraded heat exchanger. When I got my kit it still has the stock Sekalb cooler in box....
