I was thinking of forking over the extra cash and getting a Livewire instead of a regular XCal2 but I have a few questions. I know that both Livewire and XCal2 would function exactly the same as far as tuning my car would go. But would the added digital gauges of the Livewire be any good? I don't run FI nor do I ever plan to. So does the Livewire display any usefull realtime information for someone thats just going to do a few boltons.
