yeah, the AP can do this from the stock o2's right? I really was thinking of picking up a wideband, for ***** and giggles, but i dont know if i can justify an extra 500, if an AP can already read wideband o2 levels.

 

Yes the AP can read the AFRs from the stock O2 sensor.

But, IMO, this just looks soo good:

 

i agree totally,

but is there a way to just tap the stock front " wideband " instead of tapping a whole new one?

i know the PLX type widebands for supras, are able to replace OEM sensors, but stills end the wideband, and oem signals.

so in theory, couldnt you just splice into the stock wires and send that to a wideband guage, and call it a day?

 

Maybe...but the data is read off the AFR gauge is through the amount of power going through it (if i remember correctly)...so by splicing the wiring...you may not get quality readings.

Also, to be honest, I like having a second Wideband O2 sensor. Mainly because Im not tampering with the stock WO2 sensor at all...which will ensure that my ECU can be tuned properly. Because if i sent MM my logs and the AFRs were all messed up, then his job will be x1000 harder and the maps would be terrible.

 

that's a good point, but if that were true then the PLX systems wouldnt be as widely used as they are. So i'm still curious. lol

 

Well, have it! Get your car up on jacks and start playing!

 

haha, I'm not doing it unless i know it's going to work safely and properly, I was hoping someone might have a better idea on that, i might make a whole new thread regarding the issue. Seems like it should work though.

 

How has your bosch sensor held up? how long have you had it on your fi 8?

I see the aem kit comes with a bosche sensor I'm looking at getting one but what unit should I get?

 

I've had my innovate lc-1 wideband using a bosch sensor for 9k miles. I seriously considered an ntk sensor, but I could find a gauge to accomodate it that I liked. From other responses before I chose to get it, I thought the sensor would have been fried by now, but it's lasting me well and is reading pretty accurately. It serves me well as a monitoring device.

 

I've had mine for about 15,000 miles; still spot on with the Accessport AFR readings.

 

Thats guys!

 

You guys can listen to me or not. That's your choice. But just about every single time I've been in the field tuning, I've seen widebands (the Innovate included as well as the AEM being the worst) using the Bosche sensors being inaccurate. Some of them were a pretty gauge but just flat-out junk. In fact, that's one of the core reasons why I normally refuse to use an owner's wideband to tune over mine because most of the time I can't trust them if they're not using an NTK sensor.

I'm not just blowing smoke around. There's a rationale behind it.

You are 100% right. I my Bosche is burned up and is completely inaccurate now. So I have a AFR gauge that is ~2.0 off.

 

Not saying you are wrong man; I believe you. That's why I always compare it with the factory wideband readings. So far so good for me, but I'm sure it is only a matter of time before it craps itself.

 

Brian what do you use to tune and what wide band AFR gauge and sensor?

 

I use an old school PLX M-200 w/ an NTK L2H2 5V sensor. I'm on my second sensor which I purchased in late 2006. The first one lasted me three years with lots of leaded race gas being beat on it (that's one of the killers of O2 sensors, by the way). This 2nd one I started using in '07 with no lead and it's still good. I've used it to calibrate dyno widebands as well as verify the inaccuracy of others.

So you run a PLX box and gauge with an NTK sensor?

 

He did seven years ago ....

 

I'm looking to get an AFR gauge and want to see what reliable reading ones are out there, what people are using

 

Just use OBD, if you are not turbocharged and tuning then you don't need an aftermarket wideband.

 

I'm going turbo'd

 

Sure you are.
