Ok so update. Problem is resolved. No thanks really to HP Tuners as I would have probably had to wait for who knows how long but as mentioned I found someone with same problem on the HP forum and their support member gave them access to the newest Alpha firmware that is not public yet. After several back and forths they agreed to let me in on it as well and now I can write with no issues so the problem was indeed on their end. I'm more than relieved to be able to actually get it working but I would have to say that I got more help from a stranger on a forum and even in here than I got from HP Tuners after spending over $600 with them plus the cost of the Bench flash equipment and replacement ECU not to mention down time, frustration and time wasted.
I think it is ridiculous that they would intentionally disable an ECU from being able to be written to (their words not mine) and still allow it to erase the map instead of just giving you an error window when you hit write or preventing you from applying credits to that specific PCM which is really what they should have done because it would be just as bad to apply $100 in credits and then be told you cannot write. But either way, the way the handled the whole thing left me with a bad taste in my mouth. So if anyone has an LSJ, download the Beta software as this is apparently what you need for the new firmware and make sure you have the ALPHA firmware (mine ends in .17) installed before you hit write. Oh and it only works when you use write entire because write calibration still gives me the same error.
