Pocketlogger and Maft Temp. integration?
 

Using the 1g MAS you can monitor temperature using the pocketlogger software. There must not be a temp. sensor on the GM MAS becuase it sits at 83 degrees and I believe that is what the ecu sees as well, even though it may be colder or warmer outside.

Is there anyway using a temperature sensor of some sort to wire into the stock harness the signal so I can display it on the logger and maybe have the ECU see the correct temp?

This would be nice to see IC temps as well as the correct temp for the ECU.

-LightningGSX can prolly answer this one but anyone else know? Hes probably in a body cast anyway, after his GSX-airplane stunt ;)

TIA

Depending on your logger, you may be able to add an offset(the GM's output is slightly different) so the logger reads closer to actual

On a wiring diagram for my car will it show which wire it is to intercept for temp? Or how do I find which one is what? I dont have the wiring diagram so that would help... there might be one in my dsm manual though. Ill check.

These are the two parts we need? At the bottom of this page: http://www.horsepowerfreaks.com/view...~Sensors~.html

How does that tie into the existing wiring though? Which wire do you splice on the MAFT. Thats the question I was tring to say above.

The stock ecu calculates the volume of air coming through it differently than a maf does. The maf-t sets the temperature at a constant number because it only operates on one variable: the wire running though the center of it (aka 'hot-wire' setup). For it to operate properly, all other factors must remain constant.

So, this intake temp sensor is only for an AEM-type setup, when you are using a map sensor, which must also know what the temperature is of the air it is measuring. This all goes back to pervererts...er, I mean pvnrt. So, unless you plan on running some sort of ems, don't hook up that temp sensor unless you plan on your maf-t running REALLY poorly =)

The stock MAS needs to use air temp for correction because it measures airflow by counting vortexes. The GM MAF uses a heated wire, so air temp becomes part of the measurement automatically. The MAFT locks the temp at a known value and bases it calibration and the values that it sends to the ECU off of that locked temp.

What about just having a temp sensor incorporated into the system and not going through the ECU do display the temp on the logger? Or would it be easier to just get a guage or wait until DSMlink for a 1G comes out? Dont think Ill spend the money for it though.

I just think it would be nice to see air temps either before the turbo, after or both maybe using two sensors. -Maybe thats just a dumb idea though.

You can find the parts cheaper than that.

I don't really know much about the MAFT, but I don't think it would hurt much to hook up an IAT.Someone should try and see.I do know GM vehicles use both, a hotwire MAF and a IAT sensor.

it's not a dumb idea, you want to see how close to ambient temp your intake charge is. Practicality? I don't know, but it'd be hard to log that with anything but a stand-alone ems, designed to take input from various sensors, and then more various sensors, etc.
