Hey guys, I am planning on adding O2 sensors to my 509 this winter. For a better tune. Does anyone have any suggestions as to which brand O2 sensor and monitor I should look into?
Any help appreciated

you want/need dual channel monitoring?if so,I'm partial to innovate,others have had good results w/ fast.

I have the INNOVATE and I am happy with it.

++ on the Innovate as well.

No luck with the Fast dual channel for me. maybe I just got the one bad unit!!

Just bought the dual channel innovate to tune the 440 we just put together for my coronet. After I get the car dialed in, its going to be permanently installed in the pantera.

I'll report back in the next week or so as I just broke in the cam and now the fine tuning begins.

One thing about the innovate is that they offer o2 sensor extension cables (they call them dyno room cables) but will be nice for running in a boat and not having to cut and splice.

I have never heard of innovate before I will check them out. looks like the dual channel setup might be the ticket.

they were probably the first hand held that was really accurate.

Ditto on the Innovate. I've run one in my boat for the last 5 years.

Are u talking the hand held unit with 2 O2 sensors or a mounted guage.

I have used Innovate with great results. Readings were pretty spot on compared to two different dynos.
