TPS 0 % till 1/4 throttle

I have a weird problem. I have ecmlink v3 full, and when I slowly step on the throttle (ignition on, engine not running) I see my tps voltage go up instantly and smoothly, but my computer reads 0% throttle and suddenly reads 15-25% throttle after I get the to about quarter throttle and is smooth and steady after that. I already plan on replacing the sensor so I'm asking just out of curiosity. Why would the computer see a change in throttle voltage but not change the throttle % value?

you should not worry about it. It reads voltage to give this percentage. May be your alternator is weak. Mine doing the similar issue sometimes at the AFC-NEO reading.

Well I fixed the problem, Apparently when the (enable tps adjustments) box is unchecked in Ecmlink after I calibrated my tps, my tps voltage reading was 0.02 when it is checked my tps voltage is 0.63 problem solved! /ubbthreads/images/graemlins/grin.gif
