ECM Link won't link with laptop


Galant VR-4 org Post #: 1052119 posted 02/16/12 06:24 PM     Remind Me!  Send Private Message   Edit Post      
So I recently just got my car all back together and it runs ok, but could definately use a good tune. I installed the EM Link V3 chip and plugged the data cable in, hooked up my laptop and no connection or communication was found. I have the program installed on my laptop along with the supporting driver devices. Any help on why this is happening? I hope it's not a sliced wire somewhere.

Any specific error messages from the ECMLink app?

The first thing to make sure is that the V3 cable is being recognized by the laptop as an appropriate adapter.

Plug in your cable and check your COM ports in the device manager to see if it is being recognized properly. After the ECMlink application finds the cable, the rest should take care of itself. Proper configuration should solve your problem, but you can only configure a device if the computer sees it, recognizes it, and assigns it a port.

If the cable itself is not being recognized as a device, then it's probably bad... Thomas Dorris from ECMTuning was guiding me through a similar situation just the other day - new cables are $39

Try reinstalling drivers and make sure the cable is being recognized by the actual laptop first.

Depending on the laptop, I had to install the drivers with the cable un-plugged. Like gram said, it should say Serial Adapter Found when you plug it in if all the drivers are correct.

IIRC in the previous version DSMLink it was necessary to reassign any port that DSMLink wanted to use that had been previously assigned. I think I freed up Port 0 or Port 1 and DSMLink then connected without issue.

Also I know USB cables are supposed to be less troublesome than serial adapters as well as being backwardly compatible but in my experience that hasn't always proven to be the case. Check if your laptop is USB 2.0 or 1.0. I have also seen laptops with both 1.0 and 2.0 ports so try plugging the cable into different ports to see if that changes anything. I have had issues in the past with printers and external floppy drives 'mating' themselves to particular ports and failing to register if connected to another port. I'm told it shouldn't happen, but it does!

Getting old sucks ... but it sure beats the alternative !!!
