Track App - air/fuel

[zinc03svt]

Couple quick questions.
1. If I run a catless midpipe and turn off the COT and rear 02's in the tune will this allow the factory track app to still read a/f on dash?
2. How accurate are these accelerometers for 1/8 and 1/4 times?

Thanks

1.A/F gets readings from the front o2 sensors so it will still function fine.

2. Not sure, i always considered that to be more of a novelty thing than an actual performance measure.

The Ih ones I trust are accelerometer, temperatures and a/f ratio.
