FJO Wideband 02 Sensor
Apparently, there is no feed from the 02 sensor for the ECU as there was for the 4 wire Greddy 02 sensor I had...meaning the factory 02 sensor still needs to be used and one of them needs to be relocated.
Anyone know a way around this? It kinda sucks that a $300 A/F system has an o2 sensor that doubles as the stock in feeding the ecu the signal and my $1300 (with accessories) needs me to put back the stock and do some welding.

The FJo has a feed, but its of course a 0-5v output that could be used on other ecu's. I have my fjo tied into my haltech, but I also kept the second 02 sensor, as when tuning your own ecu' its nice to have a backup reading, in case the readings seem off..Max

The reason your $300 a:f system has an o2 sensor output that doubles as the stock in feeding the ECU and your $1300 needs the stockl is because your $300 is practically the same as stock (read: worthless).
Even if your wideband had a 0-1v output, it likely wouldn't work well with the stock ECU anyway, which is designed to get the practically digital signal of a low end o2 sensor (rich/lean? instead of of precise gradients).
You should really leave the stock O2 where it is and put the FJO downstream a bit if you want the sensor to last.
