I am in the process of getting my s trim hooked up and want to be as safe as possible. So i am looking at getting a wide band to keep a eye on everything, is it hard to install and where is the best place to install it at? I have pacesetter long tubes and there 3 inch ory pipe. I was thinking about where the y pipe merges but am not sure. Also where should my air fuel be at off boost and on boost 7 psi max. Thanks Here is a link to the one i am thinking of getting what is your thoughts?

As long as it's not too close to the turbo outlet I think it doesn't matter that much. Mine is in the downpipe about a foot and a half back from the turbo.

 

I have thay same AEM gauge and it's been great. I can't imagine trying to tune a turbo car w/o one.
Apparently a turbo's backpressure can affect the accuracy, so mount it after the turbo (or after Y pipe collector if supercharged) at an angle of about 15° above horizontal so it can drain condensation. I would stay at least a foot away from the end of the tailpipe so the reading isn't skewed by atmosphere.

AFR in closed loop should between about 14.7-15.2.
power enrichment mode on 7psi should be about 11.8-12.2

 

dont mean to highjack the thread but how about placement in true duals?

 

One side or the other is about all you could do. Might be able to place it in an H pipe if it's not too long.

 

I had it installed on my right side only, when 1 day the LED started acting up. Called autometer and they said to send in for repair. The other day a BRAND NEW wideband/harness/sensor showed up at my doorstep Now, I'm in the process of doing dual widebands. I have pacesetter LTs and i installed the bungs on the opposite side of the O2s, on the collector. I like the fact that i get a reading on both sides, now i just need to find another 4378 gauge.

 

One could run 2 sensors and elecrtonically average the 2 readings to allow for one gauge.

 

I kinda like the dual idea as well- lets you know if one bank is leaner than the other- could be a nice warning if something is off before things start to break.

Be nice if someone offered a dual reading single gauge. It can't be that hard to do...

 

Exactly why i'm doing it, always better safe than sorry. 1 gauge for both would be cool but i haven't seen that. I'm doing both meters in a triple pod, with the other being boost.

 

I'm thinkin 3 position toggle switch... right, left, or average both sensors.

 

"If you build it, they will come"

 

If I were rich I would buy a pair of gauges and rip then apart and try to make one myself...

I did a DynoJet WB AFR. Mounted the analog gage on the "A" pillar.
Also had a Autometer AFR Gage next to it with a 3 position toggle.
It reads Rt/ Left Bosch O2 sensor(s). Toggle is convienient access by the steering column as I drive on down the road. AutoMeter AFR gage is easy to read w/ the WB analog gage located below. Really helped me with the PCM tune. The DynoJet also can data log internal and to a Laptop via USB.

Maybe get a switch with gold contact or something to keep the voltage drop to a minimum.
