Has anybody got any experience with the new SCT Livewire vs the SCT 2 tuner? Does Brenspeed sell the Livewire? How do prices compare? Is ther any big advantage with the Livewire over the SCT 2?
It should be very accurate because the Livewire isn't depending on ecu sensors. The Livewire is just an interface that has analog inputs for a wideband for A/F. So you have to provide a wideband O2, but the Livewire will show you the results in real time. It also has an input for the boost; it is obviously not reading this from a factory ecu sensor either.
the Livewire is better than the Xcal 2 no doubt. you can datalog for long periods of time without a computer and you can set it to warn you if some parameters aren't being met, like going lean. on top of that, you've got the cool features of a shift light, digital gauges, and the hp/tq estimaters. the a/f ratio readings will be as accurate as the wideband setup you use is. as long as you have a properly calibrated wideband, the Livewire will be 100% accurate.
