Ok I've been trying to get my fiero with 2.3l quad-4, 749, $59 going as of late and got it drivable using the wbo2 display. I have it ran into ecm and registering in tunerpro but the afr's don't match the wb display. I tried using the afr vs volt table that came with meter in the $59 FJO wb table and that made it farther off. I checked voltage on wire going to ecm (0-5 volt o2 output) and it does not match the table in wb box. 2.75v=19.9 on volt meter but paper wb table reads 2.75v=16.5 but what I read from wire with a volt meter isn't correct in table either. My dad was using this meter on his 4.3l v6 with 427 $0D in tunerpro and I don't think there was any problems so I'm ounce again missing something. My dad and I edited the $0D adx, maybe we changed the conversion formula, to get info into tuner pro or maybe he just ran the wb into ecm egr pin but don't remember exactly. So I know it works, I've tried the stuff I've read except hooking up to wb with a serial cable and PC to "tune" the sensor. I don't know how to start tuning wb sensor. And I'm not sure how to do the conversion formula for FJO. The info is out there I just haven't used right search term I'm sure. Anyway if anyone can point me in the right direction I'd b ur bff :-) please reply dispite that :-) Thanks so much everyone!!!! The sensor is a FJO CWC0002------Just changing table per display, dumb question sorry bout that too :-)----EDIT: Sorry forgot to ask if I should replace the sensor because it sat on a shelf for 12 years unused, takes a while to heat up from cold? Its a Bosch sensor, found it everywhere but will I have to change settings in the WB controller? Tried to find software to get into controller but think its to old to find support for?? (I probably wouldn't know if I found it) Get a whole new WB kit?? ONe that has good user (computer illiterate) friendly Support. If I posted in the wrong place I apologize
