tunercat?

Whatelse do i need? I want to go with the rt tuner and the $ee ecm definition file.

Also where do i pick up the usb cables?

My car is a 1994 Z28.

I don't think that you can use the real-time abilities of RT Tuner with a '94. Only works with a '93 with an emulator.

I have a USB-to-OBDI cable from AKM Electronics and it works great.

Thanks for your help Dave;). I am just going to order the tuner and cable.
