Is o2 wideband needed?
Ok so here is my question.
Before i ask, my info...
87 S4 TII
streetport
Emissions removed.
550/800cc injectors
I bought the Rtek 2.0 so the i can use it after my rebuild is done, i have a couple questions.
I searched to see if i could find the answer but nothing specific, i am not sure if i need a wideband to run the Rtek. all i have is the palm for it, and my chipped ECU.
Can i tune it with all the same capabilities without one?
What exactly would be the difference with one?
and from my reading if i did need to get one, PLX devices or a Zetronix would be my best bet right?
thanks ahead
Trevor

You still need your stock 02 sensor for the rtek...remember when u first use the Rtek nothing will be really changed until u change the variables.
The ECU still needs the 02 senor to know if the engine is running lean or rich.
The wideband is a monitoring device and tool use for tuning. You don't need a wideband...but is recommended if your self tuning and you want to keep a closer eye on how fuel is being established in your engine. If your running to lean or rich.
As far as tuning...U need a wideband or some form of monitoring and to be honest judging on your questions I would have a tuner experience in rotaries tune it or you'll be rebuilding very soon.

Thanks i just wasn't sure if i need both or could just use the narrowband or the wideband. You summed it up pretty well. And yes i am having a friend that used the 2.0 already tune it for me, well help me tune it, so that i can watch and learn. I have owned 3 7s prior and did all the porting and rebuild every winter work on this one myself for 3 years now, so i am plenty familiar with rebuilding and rotaries in general, just not too familiar with wideband tuning.
Again thanks...
Another ? though..I just ordered the PLX devices SM-AFM kit with controller and sensor for 300. and so should i drill a spot for that after the stock or somewhere closer to the turbo for a more precise reading, cause from what you were saying before i need the stock narrowband..
