WOT o2 Trim

[TurboChrged93]

Decently experienced here. However, during WOT and viewing my o2 trim. It is at a constant 100% until I release. From my understanding this is "perfect" and exactly where you want your o2 trim to be during WOT...?

You do not tune by using your stock narrowband o2. Voltage differs from car to car and if it's a 1g or 2g. Your best bet is to do your tuning with knock until you get a wideband.

Just get yourself a Wideband. I recently baught an LM1 . Saves you alot of expensive dyno sessions and it's better to street tune then dyno tune due to load issues, in many peoples opinions. So ask youself, 400$ WB Kit or 100$/hr at the dyno EVERYTIME you make an air or fuel related change which you will be doing alot. I also heard ( did not research this enough to know if it's true ) that you need to retune between summer and winter. Nice 1g btw
