So with autox season coming up im in need for a datalogger for a 94 obd1 st. I have used MMCD software and custom built cable on a palm m515 on my old 92 stealth, i also used the same m515 palm with a custom built ls1m cable for my supercharged grand prix for aiding in tuning, so after doing some searching and not turning up many results im posting this up. Is there any custom built cables or datalogging options to use for a 94 obd1 st? Ive read on mro2c theres a russian built cable thats suppose to work with some russian software but theres not alot of info on it? Anyone have options or know of some?

none that I know you, you will have to build the harness yourself and use a stand alone datalogger. Or use some sort of stand alone ECU that datalogs

ST202

do the obd1 to obd2 converter cables work and may be able to use with elm scanner or something?

I have not tried obd1 to obd2 converter, but I think it does not work

None of the standard diagnostic program does not work whit TCCS obd1 standard
It is a specific "bit banging" protocol
the flow of data is slow refresh, I think two times per second, but the data is very useful

program and the scheme here ODB1
