was curious if you need a wideband sensor to see af ratio or if the hp tuner does that in its running scan? don't have either one just tryin to figure out what all i'll need to tune it properly

hptuners does show afr but without a wideband you cant get a accurate range from wot to stoichiometric ratio. Thats because the narrowband is only accurate around 14.68 AFR.

You need a wide band. Then you have to wire it into the cars computer so hptuners can see the signal unless you get the pro version of hptuners.
