Innovate LC1 problem.

[Mark 4]

I’ve been having trouble with my wideband and I think it may have something to do with a connector I have fitted.

A couple of weeks ago I had to take the downpipes off to weld in a new flexy. The sensor did not want to be unscrewed and the plug inside the car does not fit through the hole in the floor.

So I cut the wire, welded the flexy and fitted a small 6 way connector to the sensor. This can be poked up through the hole in the floor and then plugged into the mating connector that I fitted to the other end.

Tinning the wire took a hell of a lot of heat so I assume that the type of wire is not standard and by fitting this plug I may have caused it to play up.

Can anyone advise me ?

The wire and connectors you have used has probably altered the resistance and thus possibly causing the issue.
I had to cut my sensor off once. But i just resoldered the OE Sensor wires back together again..

What are the symptoms Mark?
If reading unstable, and over the scale then 90% sensor buggered.
Anyway, if needed I have spare LC-1 controller.
IIRC sensor plug (black which is going to controller) will fit thru floor hole, you just need to take rubber grommet, do bigger hole in grommet to slide thru plug, and should go.

But Glenn..., this sensor with soldered wires didn't last long

[Mark 4]

That may be it Glenn, you think if I splice it back together and solder it it will be OK.

You sure about that Tomasz, I couldn't get the bugger through.

[swinks]

Positive.
I got two sensors through that hole, stock one and wideband (running both) using one grommet with enlarged centre hole. Both plugs went thru, just try from underneath car, and just black plug, not a whole sensor.

Wouldn't recommend soldering tho. Mine previous sensor gone buggered because of this.

[Mark 4]

Does your plug look like this Tomasz ?

[foxdie]

You can get a bosch wideband o2 sensor through the hole if you either a). shave 1-2mm off the hole itself, or b). shave 1.2mm off the "nut" part of the o2 sensor (won't damage it but will void the warranty)

[Mark 4]

Are they readily available Jason and do we know how to wire them up ?

[foxdie]

Sorry I think you misunderstood me there mate, the o2 sensor that comes with the LC-1 is made by bosch, that's the one I'm talking about

[Mark 4]

Ah, OK. What do you think of soldering the wires ? Glenn and Tomasz seem to disagree.

[swinks]

Mark... I did have a sensor from Glenn, previously soldered. Anyway, readings were wrong, after year when I did update firmware in LC-1, sensor had gone. Then I took me 2 months to figure out what went wrong (Innovate forum searching, etc.). Also I bought new LC-1 unnecessary. Well, anyway there is big NO - NO in a Innovate forum about soldering, cutting etc wires.

Due to getting through the floor. I can't remeber, but maybe I did sensor thru hole. Paul (psbarham) had seen this, there was no problem whatsoever with getting even two sensors, hole in a floor is big enough (well, at least in PFL vr4 )

[Wodjno]

The 1 i have in the car now is soldered.. No issues with it...

[Mark 4]

OK, I'm going to solder it and get a new one ordered. Anyone know a UK supplier ?

I had an LC1 fitted to my car and it had been joined twice, it still worked perfectly.

[Mark 4]

Thanks for the input and assistance chaps.

[Mark 4]

Update.

I soldered the wires but it still played up. New sensor arrived yesterday so I fitted it last night (sensor through hole).

AFR at tickover is fine but it is going rich at fast idle. I just spoke to GOWF and he reckons that the simulated narrowband output from the LC1 is wrong. The manual says that it is yellow wire, 1.1v = 14 AFR and 0.1v = 15 AFR.

Anyone know if this is correct or not or can shed any further light on this.

[apeman69]

May be worthwhile checking that the voltage range for the narrowband emulation is set correctly via the software, if you haven't checked already, if just to rule this out. I'm assuming it's programmable and you don't have some weird tuning problem or other fault that means the wb is correct.
Did it definitely start after messing with the wiring or did you just notice it then because you were aware of what you'd done and being more likely to notice?

TBH Alan, I "think" it did it after messing with the wiring but I can't be sure.

I haven't looked at the software because I assumed it would sort itself to correct setting when I did the free air calibration. I'll take a look at that now.
