Ok im Planing on tuning my car soon with crome. So my first purchase is going to be a lc1 wide band with a gauge. Ive been doing some reading and i see that you have to calibrate the wideband through the ecu for tunning. My question is do i have to calibrate it if im going to only hook up the narrowband output to the ecu(0-1v). The reson why im wanting to do this is because im getting the wideband before i get a laptop and i dont know how long it will be before i get a laptop and all the other stuff to tune my car. Any help would be great. Thanks Mekal
