Ralph, I think it's Brendan that just posted again today/yesterday about the FG torque table being incorrect, there are others that are not there that are there with SCT, I'm not really going to go into them as I use these tables to help fudge what can be viewed by somebody trying to copy my tunes, but as an example there are still tables missing that affect the torque management of the 4 speed auto that I asked for years ago. PTR Xcal 2 still works with a car that is not ZF a ZF equipped car requires a Xcal 3 or X4 X4 has bigger internal memory handling capabilities and is required in some cases all must be an aussie sold one
