You just said I contradicted myself and made the comment that water was 80% oxygen. Are you that dense that you don't see it?
The TMAP sensor is typically referred to as IAT3 in GDS, or the 1st MAT pid in HP Tuners scanner which is the measured value but it's the 2nd PID that is the calculated value which the ECM bases all timing retard on. That's what this is about remember, does the ECM see a cooler air charge and not pull timing when spraying water/meth which the answer is still NO. This is VERY easy to see in person for anybody who has water/meth injection and to go out and make a pass while spraying and make another pass while not spraying. Again, if you had any experience on this you wouldn't be talking anymore.
LMAO dude, you just googled it and copy/pasted the catalyst temperature model patent and you don't have a clue how GM does it in the E92 ECM. On top of that it's Daimler Chrysler's patent. You are a joke.

On the LT4 one MAT is calculated AND one MAT is taken real time in the manifold. The first photo is the MAP sensor on the front of the supercharger, the second is the TMAP (temperature/MAP) sensor on the rear of the supercharger. One of the 2 MAT readings in HP tuners reads directly from this TMAP sensor. This sensor reads from under the internal inter-cooler bricks right before the intake charge heads down to the intake valve. It is the temperature which is used to adjust the IAT timing table in the Z06 tune. The other MAT reading is not a reading at all and is a calculated MAT just as you said. This particular MAT will not change from spraying anything because it is calculated from IAT1 located in the MAF sensor and several other parameters which may not be affected if you spray behind the MAF sensor. This is why I asked you which one you are logging? Now calm down and take your time and read this several times. Look at the photos. Its not about being right, its about getting this right for others. Now ask yourself why would GM locate a TMAP sensor right here instead of a plain old MAP sensor (like the one up front in the first photo) if they weren’t using the temperature from the TMAP sensor? Doesn’t make sense does it? You can argue till the cows come home but it is what it is.

Why waste money and void your warranty for adding a meth tank to your Corvette with no tuning or no other mods you will gain nothing but you will lose power ! That is funny stuff no one does that!
I have 800p and the real mods are worth every penny!

Now that I've taught you the LT4 has a TMAP sensor and your statement "Gen 5 ECMs calculate the MAT value, period." is obviously not true........can we please stop?
I am sure the other folks here are tired of our banter and your childish name calling. LMAO.

LOL so you went through the trouble of plagiarizing a completely irrelevant Chrysler patent to prove that you know how it calculates MAT and then claim the TMAP sensor is the actual value it uses? And here I thought you had disappeared which would have been the smart thing after your last garbage post. For the hundredth time, if you had actually looked at this before and watched the difference between spraying meth and not spraying meth you would see that the calculated MAT pid does not change and the timing is also unchanged because that's what it references. A TMAP sensor is irrelevant since it still uses a calculated MAT pid. Go plagiarize another completely irrelevant Chrysler patent and pass it off as what you do in your "circle". Again, you a joke.
