Additional Sensor Reading/Datalogging?

[Bowenaero]

First time poster - not sure if this is the correct sub-forum. Sorry if not.

Here's the deal: I want to read inputs from a bunch of extra sensors on my engine. I want to be able to read the sensor outputs while driving, and I want to be able to log the info for later analysis.

Here's what I think would be the ideal setup: I would like to use whatever sensors I want (junkyard ones like the GM #25036751 IAT sensor) and have some box to plug the lead(s) into. The box would connect to a computer and have a software interface. I could tell the software what the input is (air temp, air press, EGT, whatever) and give it the calibration info (like .3V = 5psi, etc). It will then display the data in real time (like the TunerStudioMS Gauge Cluster) and log the info in a .txt file or something.

And what I'm looking for right now specifically is the ability to read in data from (3) air temp sensors and (3) air press. sensors (one of each before the turbo, between turbo and I/C, and after I/C).

I'm basically looking for something to display and log sensor inputs similar to how MegaSquirt/TunerStudioMS does (I'm using MS1 V3). Does some program like this exist? What have you guys done?

Thanks a lot.

I found this earlier today, and it looks quite promising:

It's only $59! I'm by no means an electronics expert though, so I could be overlooking something that disqualifies it. What do you guys think?

The MS1 only has two additional analog input channels open. You could upgrade to an MS3 (which has a ton of I/O, discussed on the MSExtra.com forum) or add an MS2 daughter card and use an I/O Extender board from JBPerf.com.

Thanks for the help, Matt!
