Hp tuners/wideband help
I need to get the wideband to read on my logs on hp tuners. Need to know how to wire up the green connector on the hp tuners box.
Thanks
I purchased the car about a month ago and the wideband was already in the car. But it's programed for e85. I need to program it for 91.
If not I guess I'm just going to have to buy a new wideband.
Thanks
Why does it need to be grounded?
