    I'm getting the error message "http response failure" when trying to connect to the pcm to edit parameters, however we can read all the sensors in real time. Since the pcm is tuned with tunercat and we were trying to use hptuner, would this cause that type of error? Bricked/locked PCM?

    I own TunerCats and EFI Live, so I'm unable to help with HP Tuners questions.

    With TunerCats and EFI Live, I get a message that I'll need a code to read a flash or to write a flash to a password protected (locked) PCM. I'm going to guess, HP Tuners would have a similar message if the PCM was locked or password protected.

    From what I'm reading if the pcm were truly locked I wouldnt br able to live view sensor readings via hpt correct?

    Were you able to look at that tunercat profile I posted and see anything that struck you as possibly causing hard starting? I open that comparison text but didnt really understand what I was looking at

    I use EFI Live to view / record OBD2 sensor data. I can't remember using EFI Live to view / record sensor data with a locked computer.

    It's very time consuming to review the changes of a flash file. The .txt file I posted is the best I can offer. Something else to consider, it's always best to compare the original file vs. the modified file.
