I have been datalogging my car for some time now trying to work some bugs out and fine tune it. The issue I have been having is in the middle of logging the car I look over and the program is cycling trying to re link with my PCM. At first I figured o hit a bump or something and cable was a little loose. Well that issue was hit or miss. Would not be a problem for a few logs then would surface and the program would not even connect to the PCM at all sometimes. I cleaned and re cleaned all connections. Wasted 10 free data logs because it would not sync with PCM and would just cycle endlessly. How do I test the cable? Is there a way? I have only used the cable maybe 10 times before the issue and there is no visual indication of a problem on the pins or a case. Im at the point now where I have to buy datamaster to do any more testing, bit not sure of I now need a cable as well.?
