how to 0 out TPS gauge?

I was wondering if there is a custom throttle xgauge that starts from 0? My built in TPS gauge range is 13-78.



I was using the obd2 apps for android and it displays my TPS accurately from 0-100 (5-6% at idle since its dbw), but use of my cell phone consistently is not practical.



Thanks.
