gmj1.8

All I have is the emanage and the one main harness it comes with. Ive done searches but every where i look it seems like there is a different recipe. looks like a need ignition harness and wire it into injectors also, some sort of wideband o2 setup(does the EMB have a hook up for it), and i dont have any software what should i get the support tool or auto tune or both and where do i find the cable to hook it up to my computer. Ive seen threads like this even from years back but I dont know whats the minimum to get running on my turbo setup

thanks - Garrett
