My Ecu was done by Calum and it was supposed to cancel the O2 rear sensor, but every time i disconnect the sensor the 07 07 code appears!

Is there any way I can jump the connector with or something to prevent this happening? thanks!

The rear o2 sensor delete sometimes works, and sometimes doesn't. Because it's a resistor mod, there's no GUARANTEE that it will work. I have the rear o2 delete and it's working, but initially didn't. I would at least leave the rear o2 connected. Mine is connected but not correctly, as I have a 98 SE-R and a 95~97 ECU.

i think on the order form it says to leave the rear o2 connected, you need to get some type of voltage to lie and say that it's still working right?

mine is currently zip tied above my "cat" because i broke the threads off of it and wasn't about to buy another i should relocate to under the carpet under drivers seat if that's safe
