I've got a tuning date with you guys on tuesday and I need to get 500 miles on the motor before hand.

I had a chip on the PCM and I'm trying to use the Xcal to put on my temporary tune. The problem is, when I try to get the tune on the PCM it says it's locked. I put the chip back in a put it back to what I thought the stock tune posistion was. I turned on the ignition turned it off and tried to load the tune again with the Xcal. Same thing, it says it locked.

How do I fix this so I can get the miles on my car before I have to bring it in?

Thanks in advance for helping me out.

I got another PCM from a car today that matches my code and the tuner says the same thing as before, ECM unlock FAIL. I'm guessing the Xcal isn't working right.
