hey question for the guys with widebands installed. Where did you mount your sensors? I got the LM-1, can it be installed into the stock 02 sensor hole? or does it need to be further down stream just dont want to wreck the sensor from excessive heat.

do you mean 10cm up from the bend at the bottom of the dump pipe where it goes off to the cat? is it hard to get in and out? I'm not going to leave it in permanently. Did you have to mount it upside down to fit there?

ah awesome thanks for the picture. Where do you run your cable when the sensor is plugged in? just up into the engine bay then under the back of the bonnet and through the window?

be sure to pay attention to the wideband sensors installation and operation instructions

i mean, actually read them, pay note to the location, mounting position and direction of the 02 sensor in the exhaust

incorrect mounting and angle can really trash the expensive sensor, i think they also need direct 12v ign power as they must heat up before running exhaust gas

yeah instructions were a bit vague I thought. All they said is that it can't be mounted upside down because of condensation, or before the turbo because of heat not much else really. But I'm having a bit of a read though the innovative forum before I install.

The LM1 is the best of its kind, Any reason why a perm gauge with a wideband couldnt be fitted? Ive seen them on ebay and would prevent me thinking im killing my engine...

Would a narrow band be suitable?

I think innovative sell dash AFR gauges/displays as well to connect with their WB's

pretty sure a narrow band would be pretty useless as an idication to an AFR display as it can't tell you how rich or how lean

I believe those narrow band gauages you tune them to rich lean stock or whatever setting, but ive got no idea. Does the power fc have an input for readings from the lm1?

yeah read something about using the lm-1 narrow band output (0-1V) to drive a gauge not 100% though. The lm1 has analog outputs for ecu's I believe it can interface with datalogit and the emanage ultimate for data logging not sure about any others. That link doesnt work..

I installed an LC 1 and gauge kit

cost me 340 landed into australia from usa

didnt really work that great

then it died

I sent it back for warranty repair and they have replaced it with a new unit

but i havent got around to reinstalling

I've a little experiance with WB's, so ill throw my 2 cents in.

Manual has the preferred location and orientation that the 5wire should be mounted. Generally, you want it as close to the turbo as possible, though somewhere that wont exceed ~7000C (i think, its been a while) It's all in the manual. Just before the cat is always a good idea, though it can be mounted in a finned heatsink if you really want it closer to the turbine (or if its in a rota)

Being easy to get to, is an important consideration, as installed with the engine running and NO heater 12v will coke the refrence cell up.

Theres a fellow on the Innovative forum whos noticed how electrically "noisy" the LC1 is. Be aware of this when running the cable (more important in a perm install i guess) Reading the forums, seems heat can kill the LC1 dead quick too. Just be sensable when mounting.

...they also need direct 12v ign power as they must heat up before running exhaust gas.

Yup, its generally a 5-30s warm up time, depending on sender's temp.

Don't know about best. They've had their fair share of defective / playing up units. Be this due to the LC1 being thier most popular (most used) unit, or an inherent issue with its design, I don't know. I thought about a PLX unit, though opted for the LC1.

Innovative sell 4 or 5 gauges you can use. I "think" the crappy Autometer style single wire gauges respond in a linear fashion to input voltage, hence you could run the analogue output from the LC1 into one of these. (I think one of the Innovative's gauges would be a better option though; you get start / stop calibrate buttons.

As mentioned, theres a programble analogue output on both LC1 and LM1 that can be pumped into anything with a analogue > digital converter. Emanage, ANY aftermarket ECU, datalogit etc etc.

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
