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.

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.

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.

      Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)

      Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.

      Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
