The TMAP sensor is a single sensor that reads both temperature and pressure. The Aeroforce is reading pressure/vacuum in psi not inches of mercury. It should read around -10lbs at idle which is approximately 20" of vacuum. It may go a tad lower during deceleration but only in decimals. Atmospheric pressure is roughly 14.7 lbs at sea level so -14.7 lbs would be an absolute vacuum which exists only in theory. If you were to ever see -14.7 on the gauge, then it is not accurate.
I have an Aeroforce and keep a close eye on my IATs. Back in the winter when it was in the 50s and 60s, my IAT would hold around 80 degrees while driving around normally. Under full throttle boost through the 1/4 mile, it would climb to around 120-125 degrees. In the summer heat, like we are having now (95-100 degrees), my IAT usually stays around 115-120 degrees while cruising around with the AC on. In stop and go traffic it sometimes clims to 130. Under boost, it goes up to the mid 130s. I think the highest I have seen it is around 140. I have had no issues with belts, pulleys, etc. I always check for belt dust around the snout (indication of slippage) and have seen none thus far.
I have mine set up to read boost from the TMAP sensor that comes on the Aeroforce. Here is a writeup that I did explaining how to do it.
There has been a few of us on the forum trying to figure out exactly how to hook up 0-5V analog signal from the TMAP on the E-Force supercharger to the Aeroforce Interceptor. This info applies to anyone trying to use a 0-5V MAP sensor with an Aeroforce. I have been working on this for several days and finally got the information. First, I will say that Edelbrock's customer service is as good as their supercharger. They are outstanding and will go out of there way to help you. I talked with an engineer there and he dug up the info that I needed. Here how it works. First, you will need a pigtail from your Ford parts dept. It is part number 3U2Z-14S411-SSA. It costs around $25.00. You will unpin 2 wires from it and repin them into slots 1 and 2 in the TMAP connector that Edelbrock sends in their kit. These slots are empty. You then need to take the wire from pin 1 (1st slot) and run it to one of the anolog inputs on the back of the Interceptor. The wire from pin 2 is your 5v source wire. It needs to be spliced into the wire going into pin 2 on the fuel rail sensor. It is very important to solder and heatshrink this connection. You can see in the pictures I posted how this is done. Once this is done, take a voltmeter and make sure you have the 5V source on terminal 2 of the fuel rail connector as well as pin 2 on the TMAP connector. Once this is confirmed, you can plug up the connectors and wrap up all the wires. Now the Interceptor has to be programmed to read the signal and display the information properly. You need to enable the analog input that you are using in the setup menu. It will ask you to put in the Slope and Intercept values. The slope value is 6.5. The Intercept value is -1.5 - atmospheric pressure. If your at sea level that would -1.5-14.7 or -16. If you are at 1000 feet then it would be -1.5-14.3 or -15.8. you may have to play around with the values a little to get it perfect. You will know you are right when the boost reading is around -10 at idle. Mine is working perfectly. I have about 6lbs of boost until I get in the upper rpms. It then climbs a little to almost 7. It work great. If anyone needs more info, just pm me.
Congrats. I really like the Aeroforce. I am using both analog inputs on mine. One for wideband and one for boost. I also want to do oil pressure. I just wish the Aeroforce had a third input so I could just run the op signal to it and maintain the 1 gauge stealth look. I will have to add another Aeroforce or op gauge to read it. I will definitely add something when I upgrade to a forged shortblock.
