so i was wonder how i should do this, now i'm hoping this isnt a stupid question but here goes.

for when i install my wide band, where should the sensor go... i mean i need to leave the narrow band where it is right? the car needs that to run properly doesnt it,
now i know with some wide bands you can set it to run in narrow band mode and replace the stock o2, but i'm not sure,
do i fab up another bung or something?

thx in advance

 

it will be stated In the instructions where and how far back it needs to be in the dp.

 

You should get a new bung welded in a minimum of 18" from the turbo. What downpipe do you have? I have my wideband bung welded in just after the bend (on the flat part) on the Racing Beat DP.

 

it's for my na. no turbo for me.

this is all for my safc setup for leaning it out and getting more power and gas mileage,
but i will be getting a new corksport header soon and the wideband of choice is a innovate lm-1.

so i do leave the stock narrow bank alone huh?

 

The LM-1 manual covers the bung mounting, as well as how to fabricate a copper heat sink. Your NA engine will probably have an EGT of about 1650-1700degF.

Innovative also sells weld-on bungs, bung plugs, and a heat sink / bung extender.

You can do that if you like.

 

well i'm wondering, i cant just replace the narrowband sensor right? even though with the innovate u can make the wideband act as a narrow...

 

Im not positive, but I believe if your keeping the afm in place you have to keep the factory narrow band in place for the ecu.

 

IIRC the narrowband O2 gives input to the ECU which affects the output signal sent to the injectors and then air/fuel mixture so I'd leave it alone. Your wideband will only give input to YOU, not the computer.

 

and from the data from the wideband i take that and set my safc which in turn modifies all of what you just mentioned....
basically

 

It is possible to install the wide-band sensor in place of the OEM oxygen sensor. In this case the
meter's analog output signal will replace the OEM oxygen sensor's signal to the fuel injection
computer. EFI equipped cars typically incorporate a narrow band oxygen sensor. These sensors
are typically 1, 2, 3 or 4 wire sensors
************************************************** **********
That's from page seventeen of the manual (url in a post above).

So you chunk the narrow band 02 and install the wideband and configure it to output the narrow band 02 simulated signal to the ECU. You install the wideband in the stock 02 bung location.

Hope I'm not repeating anybody above but your last response left me wondering if you understood what was written in the valued post above.

 

ya i'v read that before i'm just kinda confused on how the whole thing would work..
you replace it and let it simulate,. but would it simulate the narrow band signal to the ecu while datalogging the wideband information so that setting the safc to mofify what the narrowband is sending to the ecu for fuel injection and what not,

i hope i'm not confusing anyone, i'm just trying to figure everything out and find out of it would all work at the same time.
but do you get my point?

 

The analog output connector of the LM-1 can simulate the operation of a narrow band sensor
while the wide-band oxygen sensor is installed in place of the OEM narrow-band sensor. Factory
equipped Analog output 1 of the LM-1 is programmed to simulate a narrow band sensor.*************************

************************************************** ***********************************************

Page 21 of that manual shows the analog output 1 being on a *Stereo* cable. That might be a extra cable you have to buy??? Got me. I own a TechEdge and a Zeitronix. Different animal and I've no real interest in Innovative since I don't own one and Find Me Guilty is on the tv.

EDIT: I'm sure someone out there has a Innovate wideband and they can chime in on what wire is which etc. You'd run analog 1 wire to the ECU where the narrow band wire is presently. Maybe splice into it. I didn't see color of wires on that document. Didn't look very hard either.

EDIT: Page 9 has the following: (Note: the LM-1’s Analog Out port is a mini-TRS (stereo)
connection which provides two analog outputs, plus a ground.)

So it seems the itty bitty stereo connector must plug into the control box somewhere (not evident from the pictures on their site) but you find analog ones wire on the other end of that stereo jack and splice it into the stock ECU 02 wire on the proper ECU plug.

 

Basically in layman's terms all you have to do is install the WB O2 into the stock bung on the header and there will be a terminal (pin) on a connector or a wire that comes with the WB O2 (read instructions to find where) that you can connect to the wire your factory O2 sensor connected to and it will simulate the stock O2.

 

ok got it,, ut one question that wasnt answer yet and guess it's more of an " do i think?"
while it does simulate the narrow band on the output 1 do you think it can do it's wideband datalogging at the same time?

 

I'd almost guarantee the answer is YES and all day long as long as the engine is running. It can data log and chew gum at the same time while outputting a analog signal to the ECU to replicate the narrow band 02 sensors output.

There must be a small stereo plug input place somewhere on the unit/controller and you just find the analog output one on the *stereo* plugs harness, and splice it to the narrow band 02 input at the ECU plug. Pin 2D on a series four if memory serves.

 

I wouldn't mount a wideband any closer than 36" from the downpipe on a rotary due to the high temps. That doesn't mean you couldn't get away with closer than that, but 36" is what several manufacturers have recommended to maximize sensor life on high EGT applications

 

36" from the downpipe? Did you mean the exhaust port(NA)\turbine(turbo)?

 

How long would the WB sensor last doing so?? 150 hours?
