Which wideband to get?

[Tachyon]

I was under the impression that the Bosch sensor that comes with the PLX unit is quite prone to failure when run in the front o2 socket? At least this was my understanding in the past that the heat kills it quite fast (at least compaired to the NTK). Has anybody run the Bosch in their front o2 housing for a good amount of miles?

thanks, I wasn't sure why the one was 50 cheaper. I will just get the 199 one then because I don't really need a display.

The Bosch sensor is much more prone to failure, no matter where you put it, compared to the NTK. But, yea, you aren't supposed to have it that close to the turbo.

Not to argue with a "wiseguy" like you Shane cause I'm clearly out matched by your real world knowledge.......BUT.......

The spec's claim that Bosch is suppose to be good through 900c?

Lot's of folks up a tuner claim they are running them up front without issue?

2 cents

[Shane@DBPerformance]

In the Innovate instructions, they recommend not exceding 900F sensor temp. Techedge says not to go over 750c gas temp. I think some of the brands recommend putting it something like 12 inches away from the turbo or something like that. We have run then in the stock front O2 sensor location before for temporary tuning, but I would put it a bit farther down the piping, if you were going to run it often. The temps really shouldn't be insanely hot after the turbo though, hopefully a lot of that heat got turned into boost.

Has anyone used this one http://www.extremepsi.com/store/customer/product.php?productid=17954&cat=747&page=1
Its the PLX R500, Looks pretty nice, but i was wondering if it sees knock on 2gs.

I was going to ask the same question... I saw them on ebay for $400 ish which is pretty decent with a display and logger like that.

It would see knock the same way the newer S-AFC2s see knock. Also somewhat similar to the way you see knock in the AEM EMS. It isn't anything like the simple, cut and dried kind of knock reports you get from something like a 1G datalogger or DSMLink.

safc2s see knock on a 2g?....

[Shane@DBPerformance]

Sure, why not? They have a wire for plugging into a knock sensor and a knock sensor is just a fancy tuned microphone that puts out voltage. It doesn't work the same way a 1G datalogger or DSMLink reports knock though. A dumb device like an AFC will report all noise and any noise, including the normal noise an engine makes while running, so you would have to build a calibration table vs RPM and then still know what is out of the ordinary noise and determine if it is knock.
