On monitoring here... I have the Livewire but couldn't get it to mointor more than 6 (I believe) parameters at a time and I ended up hooking a laptop via USB cable to the Livewire to datalog and that's how I worked with Shadowman over a course of two months with over 10 data files exchanged to trouble-shoot a pinging issue. A pinging issue that a local shop said was exhaust related and wanted me to replace my cats!!! but eventually Bill was able to email me a tune that eliminated the pinging (thanks Bill). But I don't think the Livewire is any better than the XCAL2 which is cheaper. It just loads the tunes a little faster that's all.
