There is the old J2534.dll in pcmlibrary, which is no longer needed and can be removed, and a *50 on line 87 of J2534.cs which can also be removed, as the UnsafePassThruMsg type has a 4128 byte data buffer which should be enough without the multiplication, unless there is a reason it is needed to support some particular device.
Tested and working on my P01 with my MDI.
