Just on that Jim....(others)
Does the EC OBD2 tune cable have a USB plug on the other end - silly question - of course what else would it have these days...Firewire etc are long gone...
Just wondering if you can use a more generic OBD2>USB cable and avoid the added $100. Anyone?

I just looked at the EC site ...65mm pulley+ECU+TCU tunes $1099
From a previous communication - I know they will also throw in a spare tuned TCU for an extra couple of hundred dollars if you don't want to send yours in.
