Reading this thread makes me want to stay away from the AEM system and just go with the Zeitronix. I will be getting the wideband before the Rtek 2.0 for my S5 N/A. Am I correct that the Zeitronix wideband w/ the linear output and the SNB output will work with the Rtek?

The problem with the Zt-2 is the linear WB output is the same as the SNB. So you can't use both at the same time. If you plan to keep the stock o2 sensor, then you won't have any problems.

This is a full racecar and I currently don't have an o2 sensor or a bung for one. I run oval track and am always between 6200 and 7500 rpms so it's not affected. I think I'm going the right direction here but if not maybe you can steer me a little. The next step for me is to be able to tune this car. This will be my first injected tune session when it happens. Everthing I've read tells me that I would be an idiot for not having a a/f reading to assist in tuning and also for insurance against running the engine too lean. I'm looking at going with the Rtek like I mentioned mostly due to budget reasons but I also think that buying a Haltech is really over my head.

So, I think I'll be ok with the Zt-2 if I don't plan on feading the ecu the SNB signal which I think will be ok.

Just to follow up, I did connect the output from the NGK A/Fx to the Rtek7 2.1. It was so simple, just one wire and I have the ability to log the AFRs.

Settting up the Rtek for the wideband is easy, you just select to use the ATP as an input and then calibrate it with a multiplier of 1.4 and an offset of 9, set 0 volts to equal to 9 and and 5 volts equal to 16.

I have had good results with this wideband and really liked how affordable it was.
