PCM Problem

Hey whenever i try to load a tune it will start the process using cats flash tool. Then it will get 3/4 on the first process and say "Error Pcm sent wrong data" and then bam my pcm will not do anything. After that I cant even log data using freescan or Datamaster. I have to pull the fuse and then I can get data but still not able to flash it.

I've had this happen a few times.

One of two things has usually fixed it.

1. Try to program it again right after you get the error.

2. Turn the key to the off position and wait 1 minute, then turn it back to on and wait at least 30 sec then try again.
