Innovate LM-1 aux. inputs...anyone know where to find sensor voltages?

[GILZTSIAWD]

I just got my Innovate LM-1 wideband in the mail along with the rpm converter. I would like to hook up other sensors to be logged by this rpm converter as it has 4 other inputs that can be used for various 0-5v sensors. The logging software for the pc has it where you can then take these values and convert them to actual values. I would like to tap in thing like egt, map sensor, maybe knock sensor? Just wondering if anyone knew where I could find some detailed info about individual sensors on our cars like the voltage range for them and the conversion factors to change these back to real world values? Also wondering if there anyone knew if there was a way to log the knock sensor? I'm not to sure on what kind of output that sensor gives.

Thanks in advance for any help, and if this has been discussed before, please just post the link, i looked and didn't see anything.

Before you install the rpm converter, you might want to go ahead and invest in the aux box if you really want to log EGT's and boost. The aux box has built in EGT routines and a MAP sensor as well. It is not possible to log EGT's with just the RPM converter.

You should be able to log boost using the RPM converter and any aftermarket 5v MAP sensor, like a GM or AEM though. You will have to calibrate the sensor using an accurate barometer and tire pressure gauge. Use the barometer to figure out what atmospheric pressure is outside (be sure to convert barometric to absolute), and correlate to whatever voltage the MAP sensor reads at atmospheric pressure for the first data point. Then, you will need to measure the absolute pressure in a tire with an accurate tire pressure gauge. Then connect the boost sensor up to the tire and check the voltage for your second conversion point.
Unfortunately, I don't know the conversion for the knock sensor, but I also think it would be a nice thing to be able to log.
