I would imagine the HD download has to richen the open loop...no other reason to have it like you say.
It would be good if they could make the voltage dividers that created an afr around 13.5. Not a wide enough band I guess.
I might get the voltage thingers because of how hot it gets here in the summertime (Charleston, SC). I would have to believe they would help some.

The 02 sensor will have a shortened life span if you change the Bias voltage to .798 or using the voltage splitters that do the same thing that the Bias Voltage does in the Race Tuner. It WILL richen the closed loop area to 14.2:1~14.1:1 when the voltage is altered....the down side is when the sensor goes bad the AFR will go to the programed number in the AFR table which is 14.6...(not 14.7). How will you know? You won't unless you test it with a sniffer or realize your engines running hotter than it was. The motor will run fine at 14.6:1.....but it will run hotter.
KPA is a measurement of pressure......one atmosphere is 100 KPA (kilopascals)
