the only way to find out is to plug in the actual Volvo one and compare the two sweeps.
I just received the Volvo sensor in the mail.
I get what you say about response time. When I induce a vacuum leak or change my throttle rpms from idle to 3 K I see a response on the scope, but it takes some time for the waveforms to show up on the scope.
So tonite I will plug in the new O2 sensor and see if the scope shows a faster response in reply to a a vacuum leak or if I change my throttle rpms from idle to 3 grand.
At least the info I found on the Internet gives me some idea on how to set my Time Base and Trigger.
I am also going to do my AMASS and Injectors...too bad I dont have the PicoTech hardware that lets you use a Laptop as a scope..
