What software and adapter do I need for my truck

[Rawze]

Adapter to connect to trucks: An 'inline-6' adapter or o perhaps an 'inline-7'. Can be had from china off e-bay for about $300 or so usually.

Softwares... Insite 7.6.2 is fine for what your doing. Can be had 4 free with keymakers in a few places around the interwebs. Also need Calterm 3.17 if ya want to backup ecm properly, de-mandate, custom tune, and/or edit the programming. (only the version 3.17 is going to work properly for CM870. all other versions have issues of one sort or another with cm870 specifically).
