Can the TxsTuner replicate the stock af sensor?
I was wondering if anybody has done this. I think the tuner has a wideband output on it that can be configured for narrowband as well. Cant this signal be spliced into the stock harness, permitting you to run without the stock af sensor completely? Ignoring cells, blah blah, can it be done?
Also you'd have to block off the spot in the headers where the stock sensor was. Dont you think the lack of a sensor would increase the flow of the headers? You cannot argue that it isnt in the way of the exhaust gases and restricting flow, but how much is harder to figure out. To remove the sensor would cause the exhaust gases to flow easier through that portion of the pipe, maybe only 5% but perhaps maybe 20%, who knows? You definitely wont Lose any power, only gain. Jeff

yes ive done it for the rear O2.
you can also get a "heater" sim which is just a big resistor. http://mysite.verizon.net/vze7erz1/id10.html Quote:

aaronwrx, it looks like you simulated the rear sensor. What about the front? thats what im interested in doing.

Front sensor is not the same as the rear. The front is not a standard narrowband. From previous discussions on the sensor, I doubt the tuner could drive it.

Yea, I want to remove it and have the tuner spoof the stock ecu by simulating the front 02. The only problem I can think of is the warm-up period...what does the tuner output during that time?

Stock front sensor doesn't measure 0-1v. Shop manual on my '05 shows 2.8-3.2v on the positive signal, 2.3-2.7 on the negative at idle. From the description it sounds like the ECU is driving a specific voltage (which is not static) and expects a range of current outputs. You would need to spoof the current, not voltage, if this is correct.
