This^^^^ You may not think you need it now but eventually you'll buy or need to work on something newer and your scan tool ends up being outdated. You want something that reads all modules not just engine controls.....everything lives on the can bus...you'll want access to all of it including modes 1-10 on the generic OBDII side for checking raw data and monitor status. twocents
