But then they follow that with "it might be the cable". The $35 dollar cable? Probably should have started with that but fine, whatever. I asked for a pin out and they say they don't provide it and then tell me to try to bench flash etc etc. So I do a small search and find a pin out of the cable on their own damn forum. Do a continuity test and boom, VPW circuit is smoked. The end, problem solved. Overnight a cable from Summit Racing. So it brings the total cost to around $400 bucks (granted I overnighted the 35 dollar cable). Lesson learned. I should have trusted myself and did some further snooping instead of depending on them but I didn't. However, I feel they should have released that info about the cable, at least just the VPW circuit since that's the main issue. Virtually everyone has a multi meter but not everyone has a bench harness. This could have been a quick fix that turned into a debacle.
How does HP Tuners tech department not know that a smoked VPW circuit could be one of the reasons why it wasn't working and why didn't they suggest trying the cheapest solutions first? This is basic 101 trouble shooting.

Should tech departments start hiring customers as technical consultants?

After spending such an amount of money on something, I felt put out but it is such a useful thing to have I ain't giving it up. I just try and get more computer savvy as I go.
I am a dope and this is coming from a guy who worked in the tuning industry. I used to pin out the cable for people having issues before I had them send tools in for RMA. Anyway lesson learned, all is well that ends well. Still annoyed that it could have simply cost me 35 bucks but whatever.

This was my main argument with him. He stated its hard to diagnose a cable. I JUST DID IT. It took me two seconds with a multi meter. I used to help do this for a living and I always went to the cable first, 9/10 it was a broken wire inside the cable itself. However I figured this guy should know so I will just take his word on it.

ANYWAY, I received my cable from Summit Racing today since I overnighted it and it works perfectly now. Lesson learned!
