Has anyone figured out a way to get D1/Urban, aka "hold manual first" working with 7603 ? I haven't found any XDF's referencing it, but it must have been available stock (I believe).
I had it all working with HPtuners, but those guys just pissed me off far too many times and I've given up on them.

Assuming no one's ever got this working, can someone point me in the general direction in terms of how to determine if 7306 is even capable of D1 urban, and if so, a rough idea of how one would go about determining the correct table defs?
