My o2 sensor was very messy when I had the exhaust off last, all I did was give it a blast with some compressed air to clean some of the carbon out but really, it's toast. You can order one from Mitsubishi at like $300+ or you can look up what Carsten is using on his ride. Forgotten the name but its an after market unit with tuning abilities once you hook it into an after market computer. Good luck man.

Carsten had an LC-1 and they are rubbish - not sure what he's got in there now. Get a PLX unit if you want an aftermarket wideband sensor, otherwise there's a few of us trying to work out if there's an cheaper aftermarket narrowband (works like factory) alternative available, as the O² sensor is $260 even from Mitsubishi Japan.

I doubt Haltech would on-sell them if they're rubbish Trev. Carsten probably was just one of the unlucky ones that occurs in production of virtually every electrical product. Having said that however I'm not against the PLX ones, as I've not heard anything about them I'm not really in a position to comment. They are well priced though which is always a good thing ;)

i have a innovate lc-1

nothing wrong with it as such, i was just unlucky mine randomly died,
has been known to happen,

i was more annoyed with the company i bought the unit from,
there RMA service was terible!!

i got a brand new unit and o2 sensor replacement in the end,

from the reviews the innovate unit is the better of the aftermarket wibebands you can read

there isnt a specific unit,
its a one unit fits all, you just wire it as needed

And install a threaded bung if necessary - depends on the design of your original.

Sorry Trav, let me qualify that - a LOT of people all over the planet have been having trouble with the LC-1s, not just on VR4s but with the units in general. Quite a few of these people have had trouble with warranty replacement as well with a number of companies including the manufacturer. Which leads me to believe that the quality of their goods isn't fantastic, their quality control is poor and their company policies with regards to RA and distributors isn't great either. Despite the apparent performance of the units in good, working condition, that's a whole lot of low scores which leads me to the conclusion that they are in fact rubbish - there's no point in having a well-designed product if one in three (or even one in ten) is faulty.

Feel free to stick one in your own car, but that's not something I'm comfortable gambling with, thanks all the same.

the bosch one supplied with the innovate units fits in place of the old one, no need to fit the threaded bung supplied

Thanks Carsten - thought that might have been the case for VR4's, but it's not always for other models... Not that we care too much about other models ;)

Just a dumb question...

Can the Innovate LC-1 wideband O2 sensor replace the factory one and work with the stock ECU?

yes,

the Innovate unit, and a believe also the PLX
can do both narrow band and wide band at the same time,

so you just wire one output from the wideband controller to the factory ecu ego input, and have this set to output a narrow band (emulate a factory output)

then you connect the out output to a gauge or aftermarket AFC if it has the function

Oooh, looks like Michael from Stockholm has found a relatively cheap stock replacement!

i have heard reports of these aftermarket EGO's not being as good as the OEM part, apperently they react slower and there lift span is shorter...

it was brought up on clubvr4 some time ago, it may have been kiren (sp?)

Thanks for that, good to know - I thought it seemed a little too good to be true :(

Yep.:)

Bottom line was that an aftermarket 'univeral' sensor will probably work, though when I spoke to Eurospec (A garage that a lot of CVR4 use and trust), they reckon that whilst they do work, the response rate isn't as fast (they can't 'swing' between rich and lean quite as quickly and therefore the feedback to the ECU is at a lower resolution) as the original mitsu sensor and also their lifespan is not as long either.

Having said that - they are cheap and if you have a stuffed 02 sensor then even if you need a new sensor every 12 months @ £50, that's at least 4 years supply at MitsuTwitty UK prices!

Oh.... And seeing as it has been mentioned - The innovate LC-1:

I fitted an innovate LC-1. And it never worked properly. They are really fussy about earthing - Any slight earthing issue and it throws the readings out. Couple this with "Backup" from Innovate that's along the lines of "Our products are all PERFECT and it must be your installation!" (That's my interpretation anyway - check their forums!) And you have a pretty rubbish product IMHO.

Ironically, the reason I've got to change my LC-1 is because of a genuine fault! Earlier this year they produced faulty batch where every time you power cycle the device, it looses all calibration data- And the place I bought it from has gone under!:mad:

So yeah, I've ordered a PLX instead.

K genuine O² sensors from Mitsi Japan are around ¥25,000, so around £120 plus shipping. Might be worth letting CVR4 guys know if they want genuine ones, 'cause they just cost waaay too much from local dealerships.
