Any one know what's out there as far as data loging ALDL/OBD1 systems?
As far as cost and how many things they can log at once?
Has any one ever herd of any one useing an O-scope meter to log data?
I was just looking at getting a Fluke 123 0-scope meter for a nother project. It will fill the huge gap of functions that my little radio shack meter won't do. Then I figured out that I could adapt it to log data from 2 inputs from my car. Up to 60 seconds with just the meter or as long I want if I plug it into to my lap top.
Plus I could use it to log data on any Fuel injected car not just ALDL/OBD1.
As long as I could get values for what ever the meter picks up and use the provided sftw to change the volt or frequency values to say degrees F, O2 count, TPS volts, RPM's, injector duty cycle or MAF readings.
I was thinking log RPM's with say O2, MAF or injector duty cycle.
Thinking I will have to log RPM's with most every thing for the base line. Or any thing with any thing, only probem is that it will only log 2.
The fluke 123 is over kill for this appication, this is a super senctive piece of test equipment and other electronical engine functions might interfere with it (I can flip the test lead around in the air and the meter will pick up the small voltage inducted on to it by earths magnetic field).
I have one of these where I work and play with it when ever I can on mid shift.
