lambada sensor?

[SCHWARTZ]

does anyone know if i can connect the lambda plug from the loom to my innovate Lc-1 so they can both share the sensor to aid my fueling issue?
If so what wires do i connect from the loom to the Lc-1 as i cut the connection off and dont know what colours the wires are:ashamed::laugh:

If this isnt possible does anyone have the origional lambda and loom plug kicking about? long shot i know:D

[SCHWARTZ]

found this on innovate website. output 2(brown) is being used for my gauge so could i use the yellow wire as its a narrow band signal? Would that be all the ecu needs?

6. Optionally, the YELLOW (Analog out 1) and/or BROWN (Analog out 2) can be connected
to the analog inputs of other devices such as data loggers, ECUs, or gauges. If either one or
both of these wires are not being used isolate and tape the wire(s) out of the way. The default
analog outputs are as follows: Analog output one is 1.1V = 14 AFR and .1V = 15 AFR. This is
a simulated narrowband signal. Analog output two is setup as 0V = 7.35 AFR and 5V = 22.39
AFR.

i've got the same setup.

yellow for my display and brown simulated narrowband for ECU

ace il have to double check what way round mine is. do you know the colour of the wire from the loom? im guessing you had to cut the connector off.

[sieger]

look for a yellow spade conector.

will check it on monday

[SCHWARTZ]

A yellow spade off the loom? I dont recall seeing one but i have cut a few things off it. is it near the connection for the origional lambda plug?

[sieger]

somewhere above the gearbox

[SCHWARTZ]

the only yellow spade connector i can see here is the test point g3. is that the one?

Interesting this, so in theory your saying if i also join that g3 connector to my aem afr yellow the ecu will run as if its got a oe lambda connected?? i.e better fuel ecconomy?

[SCHWARTZ]

thats what im thinking just trying to find out what wires to use. that g3 connector says its a test point so i was thinking it would be one of the wires that went to the lambda:scratch:

im not sure if you know schwartz but that yellow g3 connector plugs onto the oe lambda, the oe lambda has two connectors but im unsure why, its one of two plugs anyhow, i had an oe lambda but it was welded into my old downpipe before i put t28 on and used new downpipe, that g3 connector takes a reading of some sort but i also could do with knowing an answer to this:D

ahh makes more sense then. no i didnt know that matey i thought it was some kind of test point for a diagnostics computer or something.

So it looks like its that wire from the loom but would the ecu need a wide or a narrow band signal? I assume narrowband as it dosnt need to display anything:scratch:

[sieger]

yep, thats the connector, standard lambda has a 3 wire. i just followed the lead and found the yellow spade connector.

[SCHWARTZ]

sieger does your car fuel better having the lambda plugged into your Lc-1? im having a few issues with it being all over the place:rolleyes: I have saab reds and looking to run 1.5bar boost but thats making it hard to get it fueling good at idle.:sad2:

when it comes to that type of stuff mate im stumped sorry, at a guess yes i would say narrowband but sieger might be better to help or maybe scoff as thats one of his specialities..

if its also any help schwartz a naturally aspirated volvo 480 lambda sensor will also fit, i checked the bosch numbers online the other day.

[SCHWARTZ]

Il bear that in mind matey really hoping I can do this with what I have got.

i fuels fine, last trackday i wound it up to 1,4 bar ( with 230cc injectors :P). did run pritty good

[REGGY5GT]

i spoke to a friend of mine today and he mentioned something about putting the laptop onto the afr kit and setting the output of the yellow wire to the specs of the standard volvo lambda, so theoretically the voltage of the yellow gives the same signal to that g3 connector as if a lambda was connected, i hope this helps you out a little schwartz...

[SCHWARTZ]

Cheers matey I have the programme and cable, think il have a go at it. Just need to find out the voltage that the ecu needs then I guess.
Cheers for all the help guys:agree:

no exactly sure what your trying to do. wideband kits use a wideband sensor, volvo ecu uses narrowband so they wont be compatible. are you tryin to use a wideband but through your kit then tellin the ecu a narrowband signal? early ecus dont use a sensor, later use it but when unplugged ecu runs closed loop, basically what its been programmed to do. when plugged in the ecu runs open loop and will adjust duty cycle slightly to help compensate, not exactly sure how much but dont think it would be alot, say 5%. dont think you'd get the adjustabilty your after on that setup?
first pic is where the lambda connector is at the end of the loom, opposite end from ecu's. there's 2 connectors, the 2 pin one is for the probe, the other is the one in the second pic, the yellow connector your on about? i think its a test point for the ecu.
markey mark may have some sensors but most narrowband ones wil do.
regards the red injectors, you'll need some sort of bypass hole, from memory 32mm? the is best done closest to the turbo, if its close to the afm it seems to make it read funny

[SCHWARTZ]

Cheers haz, The Lc-1 has 2 outputs wideband and narrowband, I was looking at connecting the narrowband to the loom hoping this would aid part throttle driving? Or would this not be the case?

You can do that Gary but it depends on the narrowband signal that the LC-1 gives out as I found my AEM didn't give out the correct signal although there was prob away of programming it to do so I gave up in the end and left mine slightly richer

[SCHWARTZ]

Yeah I have the programme n lead to re-programme it but me n computers don't mix so if I have to do that it will prob stay as it is:D

Gary, have you tried wiring in the yellow Outpu 1 wire without programming to see if it works as this should be a typical narrow band signal 0v - 5v (7.35 afr - 22.39), if you can find out what your lambda range is if needed it looks pretty simple to programme the LC-1 with a laptop through LM programmer

[SCHWARTZ]

0-5v says its the wideband signal tho dosnt it?

[James5]

0-5v says its the wideband signal tho dosnt it?

I think you could be right not had a look at the guide again yet but I assume you just need 1.1v-1v literally so it just lean or rich signal, think you will have to programme that in

[SCHWARTZ]

yeah that is the yellow wire narrowband signal 1.1-.1 i may just try connecting this and see what happens:scared::D
