i have attached it to my turbo timer and when it was cold it was rading above 1volt and then it must have gone to closed loop and went to 0.06 volts. but when you give it a consistant amount of revs it goes up . and when you boost it it reads about 1.2 volts. is this right??

Assuming this is a narrowband oxygen sensor:
Cold reading above 1 volt may be a little rich on warm up, but not unusual.
In closed loop the sensor should switch continuously between 0.1 and 0.8 volt.
When idling at least 2 times a second, the higher the rpm, the faster is should switch.
0.06 volt is very, very, very lean!
On boost it should be rich (high signal), but maybe 1.2 volt is just a little too much.

What do you want to achieve with attaching this sensor to the turbo timer?
What car are we talking about?

It's A green top. Just a good thing to know. It's part of the turbo timer so I just joined it into the sensor

I don't like turbo timers. Is the chip setup for use with this timer?
Otherwise you risk damage to the engine.

It's stright of the sensor not the ecu
