so on the ECU side we have pin 1 for DATA pin 10 for DIAG and pin 12 for GND so i just splice into the wire for pin 12 with 10?? cause on the LAPTOP side there are only 2 wires.....(yes im slow... it's not my fault i was raised un moronville errrrrrr.....mormanville;) )

I would say yes - To put the ecu into logging mode you connect those two wires you mentioned.

How do all you guys know how to make the cable just from looking at the schematic? My friends and I all looked at it and we have no clue what the means. I wan't to make a cable for my 91 talon. Aslo I thought there were supposed to be three wires in the cable?

Thanks,
Brian

There are three wires at the datalogger end, ony two at the palm end as one of the wires splices into two... making three wires.

Does anyone have a pic of the whole cable and a close up on the ends for a palm?

There's nothing in it to photo really, tx, rx and gnd... the circuit diagram says it all...

Hey guys thanks for all your help I got it working. :D I figured out what my problem was I am using pocketlogger software and with that you have to switch pins 2&3 then it will work. Now if i could just get it to work with my sony clie that would be nice. I have been testing it with a friends palm because I know it works. Anyone useing this cable with a sony clie? I think I am going to try and make my own serial cable and see if that will make it work.

There is a list of compatible devices on the mmcd stie (or teh pocket logger site if you are using pocket logger software)

It depends on what palm os the pda uses.

Will it be a problem if the cable is connect to the ECU permanently?

Nope - but if you are adjusting timing - you have to disconnect it.

alright...finally got everything soldered up (pretty positive i wired it right) and the palm doesn't get any readings. it behaves just like when i run mmcd w/o it plugged in. is it supposed to beep like when i hotsync to my computer? any suggestions on what might be wrong?
thanks...

Have you started logging? Start up mmcd, open a new log and unpause...
Author:  thehelldonkey [ Tue Jun 15, 2004 4:06 am ]
Post subject: 
yep. did that.
car's running. unpaused (selected sensor's flashing down in the bottom left). just no data coming in.
the switching diode has to go in a certain way, right (ie: it can't go backwards)? mine has the little band on the side farther from the palm (if that makes sense)...is that wrong?
please and thanks guys.
