Converting Raw OBD2 Data

[donaldb]

Anybody know of a tool to convert the raw data (voltages, etc.) to actual numbers, temperatures and pressures?

What do you have now? Ipad, Droid, files of obd2 data?

Assuming you have not logged any data yet, you can use a Dashdaq (Drew Technologies) that logs and displays a few gauges. Built like a navigation device and plugs into the odbc connector. Not as cool as those wireless Ipad & Droid products, but probably more precise.
Also SCT makes a handheld unit can integrate a laptop to the obd2 for data logging and reporting. It's also useful for loading new tunes.

How about a sample from SCT Live Link

Intake air temperature data ranges from 29 to 48, since is 80+ degrees in Houston those are actual temperature, how do I convert them to degrees F?

Engine coolant temperature ranges from 90 to 90.1, same comment as above how do I convert to degrees F.

Accel pedal position ranges from 19.21 to 82.71 how do I convert to percent open position?

Ignition timing advance ranges from -4 to 52 how do I conver to degrees advanced?

go buy a innova diannostic tool then you can read it in real time

Why would I spend money to get the data I already have. I would believe one if the many smart folks on this forum have the information. Im not looking for a different way to get the data just the right way to interpret it.

So you have a SCT tuner and are using Live Link?

The Celsius to Fahrenheit, just use an online calculator.

As for those other values, the pedal position numbers you have are the percentages, and the timing numbers are the degrees. Nothing to convert.

Use excel, add another column, use a formula and reference the original column to convert values.

So in the end you will have two columns of the same channel - the original and the new one converted.

I have done this for temperature but not for throttle. Seems there was another channel that reports 100%
