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

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.

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.

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?

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.

The LM1 is the best of its kind, Any reason why a perm gauge with a wideband couldn't be fitted? Ive seen them on ebay and would prevent me thinking im killing my engine...

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.

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..

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.

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
