Need Help troubleshooting my ECU Wont connect to computer.
 

So i bought my DIY MS off of a forum user here who build them for individuals and ships them out. I received it about a year ago and it connected to my computer no problem but the time that I was going to install it I ran into some issues with the motor and I just had to fix those things in order to head off to college. I have been talking to the folks at DIY autotune but nothing seems to help, I bought their trouble free cable and that doesnt work. I tried to contact Brain who I bought it form on here but he never responded. I was willing to pay for shipping and just to get him to look at it and hopefully fix it. I dont really understand what the issue could be as it just sat in a drawer all winter and not touched then when I tried to install it about 3 weeks ago I get nothing from the original cable i first used last august that connected just fine and even the one bought directly from DIY autotune themselves. It is just frustrating. If anyone knows anyone who understands these ECU's well and wont cost me nearly 200 to get iti fixed when it is basically new as the folks at DIY autotune had given me contact info for a man in florida. But wanted to charge me 200 before shipping just to try and fix it. Any help is much appreciated. All I want is some turbo noises.
