The rear narrow band sensor in most vehicles is there to monitor this removal of hydrocarbons, not lambda (AFR). How much readings are affected will vary with cat efficiency. The lean shift will generally be greatest near stoich and drop off as you move away from stoich and cat efficiency plummets, but the actual amount is hard to predict. Errors in the .2-.3 AFR range (.020 lambda) are common.

I'm not sure I follow the math on this. An SSI-4 is about $100 and provides four inputs which can be used for voltage, frequency, RPM, etc. and are suitable for boost sensor.
An LMA-3 is $200, but provides five inputs and includes the MAP sensor and two axis of accel (for better road dyno numbers).
We actually sell the LC-1 w/SSI-4 for $299. This is $20 more than a Zeitronix unit, but the SSI-4 can take RPM from ignition sources, the inputs can be repurposed, etc. and the LC-1 itself is a dramatically faster instrument. But even buying the pieces individually, I don't see how you came up with 300+.

I was referring to Boost AND Exhaust temperature
LMA-3 Multi-sensor Device (AuxBox) $249. in addition to the LC-1 $199
Zeitronix does all of this out of the box.
I paid $180 for Lc1 from StripperMotorsports. They sold me the kit that comes without the sensor - bastards. Over the phone he said it was the complete kit, serial, controller, sensor and all. I had to instal it in a hurry so I didn't have time to send it back I got stripped
I had to purchace the Bosch seperatly for another $80
Don't every trust a vendor with borderline underaged strippers covering the ir web page lol

If you need analog inputs to tack into existing sensors (ala Zeitronix), you just need an SSI-4. SSI-4+LC-1 is $299.

1) AEM Uego
2) Plug and Play install, routed o2 sensor through factory o2 sensor hole in passenger side floor panel (tight fit to push the AEM through with the factory wire running in there). I added an o2 bung and run a total of 3 o2's front / rear w/CEL fix / wideband.
3) Had to make serial cable and use serial to USB converter because my laptop doesnt have a serial port to log in evoscan. Used existing serial cable and cut end off and connected 2 wires. Note instructions are for a male connector but you will be attaching a female connector so make sure you do the right pins. Check continuity if you use a serial cable to make sure you have the right wires.
4) Seems accurate. I dont have another one to check the accuracy of this one.
5) Have only had it installed for 2 months. Looks nice and works.
6) None yet. Not compatible with mitsulogger yet.

Did you find good install instructions? I'm going to install mine this weekend. I plan on routing the wire through the pass side fire wall hole that leads to the glovebox. Any good wires to use in there? Grounds? I'm going to wire in the led with the push button so I can easily calibrate it and determine if there is a problem. I did it when had the Subaru, it was a pain in the ***, but I drilled two holes below the center vent for the led and push button. Any help is appreciated. Thanks.

IS there any reason that i cant pull my factory downstream O2 sensor and use the bung to place my wideband? Then simply place a "simulator" on my factory o2
I dont have a cat btw.

A simulator only simulates the narrowband signal's output, In order to completely remove the stock O2 sensor, you'd have to create a simulated load on the heater circuit so you don't throw a CEL. It can and has been done before, but the resistor required to do it would generate alot of heat and can burn stuff that it comes in contact with. I saw several posts about how this is done over the years.

but since i dont have a cat there wouldnt be a problem with placing the 02 sensor there?
my downpipe/catdelete is coated, i dont really wanna drill a hole in it to place the wideband, but if i could put it in the cat-back secition of the exhaust it would make life easier.

Yeah you could put it there.. Location isn't as much of an issue as long as its not in a location that it can get damaged.. Its preferrable to be slightly closer (somewhere in the downpipe) but not too close to the turbo.
FWIW a common misconception about the catalytic converter is that you can't tune with a wideband after it.. You can, but have to be aware of the affect it has on the AFR's after the cat.. But this doesn't apply to you because you don't have one.

Thanks, So this is what i have extrapolated from this thread, Ill update the first post unless someone has objections:
AEM UEGO
1) Nice Gauge Included
2) Laptop Interface requires some fabrication
3)No Bung Kit Included
Zextronic Products
1) 5v Output allows versitility
2) Includes Serial Output
Innovative
1)Cheapest option, (not sure which Model)
2) Avalable with or without gauge options
3) easiest set up, so long as your computer has a serial port.
any comments?

All 3 have both serial and Analog 5v outputs
All 3 have bung kits included
AEM has a gauge built in (if you got the Gauge type UEGO)
Zeitronix package includes the display box if you ordered a package kit. It also has other sensors and inputs you can log (Mitsulogger includes all of the sensor inputs, Evoscan doesn't as far as I've read)
Innovate was the least expensive unless you want the gauge, Logworks software is fantastic, and its additional logging components are flexible and designed to be modular.
Installation on all three for basic AFR is more or less the same, and pretty easy. The complexity goes up as you have to deal with difficult wiring harnesses to run through the firewall, and additional sensors..
