Instead of me searching for “dyno”, can ppl list names of places that have dynos with wide band o2? I need to get it done before mid May ---

alright, thanks. now for 1 more question, i had stropes tell me today that they need to weld a bung in for the air fuel ratio and ive also heard you can just pull the o2 sensor out and go from there. does it matter? obviously i know w/o the o2 sensor, your car may not run right, but ive heard both. ---

The wideband on my MR2 can output a signal to mimic the stock O2 sensor during cruise. This way you just need the one sensor rather than welding another bung. But as was said above, if your ECU is normal, the signal from the O2 sensor is not used during WOT. Just pull it out of the bung, ziptie it out of the way and screw in the shop’s sensor. ---

Can someone clarify this - if I remove my O2 to insert the one for the dyno, will that screw up the A/F readings across the range? If so, can Hybrid weld a bung in for me? Where would be the best place, anywhere before the cat? Does my Jet Hot coating screw up the welding? [Next page](https://forums.speedlife.net/t/pittsburgh-dynos/173521.md?page=2)
