I have dsmlink v2 and I am having a little problem. I went to pull a log on it and it does nothing. I can link up and adjust what ever and everything works but it wont log. I took a 10 mile trip with the log on and I got a mixed up log about 4 sec long and that's it.

I have reinstalled the program and also have checked the ground. I had a problem where the ECU was shutting down and the fuel pump would kick on and off, so I used a friends ECU because I though mine was going out and got the car home and messed with it again and found out the EPROM chip popped out, so I fixed that, but before this I had no problem logging.

i know you said it will connect and you can make your adjustments as needed but when you go to log it won't... if i were you id check the basics and go from there. good luck, i know these issues can be frustrating... i had a logger doing the same, it would connect but when id do a run it wouldn't stay connected. :mad:

i pulled this off of dsmlink wiki for 1g connection diagnostics

Diagnostic port wiring
When all else fails, check the basics. Here's some information posted to our forums related to basic checks you can perform on the 1G diagnostic connector in the car.

First, make sure the car's ignition is turned on when you're trying to connect ECMLink.

Examine the cable for any broken wires at the car end. With the ignition on, measure the voltage on pin 10 of the car's diagnostic connector (connects to the V2 cable's pin that has a white wire) with no cable attached. It should be about 4.5V (3.5V for a 1990 ECU). Measure the voltage on pin 1 of the car's diagnostic connector (connects to the V2 cable's pin with the green wire). It should be pulsing, indicating diagnostic info. Check that pin 12 of the car's diagnostic connector (connects to the V2 cable's pin with the black wire) has continuity to ground.

Pins in the diagnostic port
This one's pretty rare, but it does happen. If one (or more) of the pins in the car's diagnostic connector is loose, then all your checks with the multimeter will still work fine. But when you plug in the DSMLink cable, that pin (or pins) can actually just "push in", away from the cable, and simply not making contact with the cable. Check to see if that might be happening. Try grabbing the pins in the car's diagnostic port one at a time with a pair of long nose pliers and seeing if there's any movement as you push in/pull out on them.

USB adapter (V2 ONLY)
The goofy 1G ECU baud rate makes this platform very sensitive to which USB/DB9 adapter you can use. Our users have reported only a few that actually work properly. You can get more details from the USBToSerialAdapterInfo page.

Red power wire (V2 ONLY)
Some early 1G cables had a separate red power wire. Please confirm that this wire is plugged into a powered fuse box port. The cable does require that this wire be connected to a 12v power source as listed in the install instructions or else it simply will not work.
