When the pcm was locked you could still read the pcm and tcm with hp tuners couldnt flash anything without it being unlocked. So I had it unlocked and when I got the pcm back it showed read entire for engine and could flash the engine but it didnt even have the tcm menu where it says read or not to read was blank. I know the engine side has a controller and the tcm has a different controller but both go thru the pcm. anyone ever had this happen? Thanks.....I e-mailed the company about the issue but wont hear anything till next week. In other words before I could choose to read the pcm or tcm or both now only the pcm
