What is the OSID of the PCM so we can try to find a stock bin from a DHP tuner. I do not know why it would do that but you could try posting on Tiny Tuner | Download Tiny Tuner software for free at SourceForge.net there is not much activity but if people start posting for help and changes the project might improve. There are cars people are adding to TinyTuner but have not released them yet.
