What three terminals on the data link connector are you supposed to plug into to be able to log with a palm and the software?

 

jeeez good luck with this. been trying to figure this out for my buddies vr-4 and it's a pain. i'll post up some info for you when i get back to my house.

 

I'm guessing pins 1, 10, and 12, as those are the data and timing connections, but any help would be great.

 

I really don't know anything about DSM ECUs, but many ECUs (honda, etc) have a serial port inside the ECU that is usually used for datalogging on pre-OBD2 cars.

 

Thanks, I'll take a look

 

yeah, 3kgt did not have an internal connector.

 

I found my answer. For obd 1, the cable has three connectors, one single, and one that splits to two. The spliced ends of the cable are grounds. The single wire is the signal wire which reads data. The logger cable connects to the terminals as follows

x / /
/ / /
/ / /
/ / x
/ / /
/ / x

The x's are where the connectors go. The top left is the signal lead. Thanks for the help.

 

Cool deal, I'll cross reference those to the ones we tried. I think it's his software being bogus though, I'm pretty sure all the wiring was done correctly. Congrats on getting it working and thanks for the info.

 

This is correct.
