Its much better to do pre cats. In my commuter car,I swapped out the 2nd o2 for the wideband (post cat) and it works for the most part but its very delayed.
Since this ecm uses alpha-n its not worth me moving it, but the delay could really get you going in the wrong direction. I had the exhaust shop weld mine in where the primarys meet the collector in my camaro Last edited by squish72; 10-27-2020 at 09:40 AM. |
