I run the wb02 unit too and am very happy with price and performance. have often run it together with a motec sensor in the exahust and it always reacts sooner but reads the same

I have had both an LM1 and a WB02 and had no problems with either of them. On the dyno, the WB02 gives the same readings as the calibrated Motec A/RF meter, except as Dunk said, because the WB02 is closer to the engine it reads changes faster. I have killed a couple of senors due to the low mounting point and high ripple strips, the new exhaust has a high mount. On the Stagea and the R33GTST I use the standard lambda sensor hole. I find it best to tune open loop, so not having the standard lambda sensor is not a problem.

Logging the A/F ratios is an OK idea, but watching an A/F ratio gauge is truly a pain in the ass. Every tiny change in the throttle position swings the numbers around dramatically. It's not like oil pressure or the temperature gauges that stay pretty constant and you can tell at a glance if something is wrong. The numbers are constantly jumping around and almost impossible to follow. The only time the numbers are constant enough to read and be meaningful is at a consistent 100% throttle and, I don't know about you, but I'm far too busy watching the road at that sort of acceleration rate to pay much attention to a gauge.

Cheers

I had a fist full of cash for Pete 5 years ago, though heard from a few very reputable tuners about their issues with rapid elevation changes messing with the output. I saw a calibrated techedge unit compared to a motec (the older design)

Left a dirty feeling in my mouth, and didn't want to risk my motor (or others) with a device from a mom and pop operation.

I know the US Rx7Club uses (used) em like hot cakes... but Innovative, PLX make sell a LOT more :D

Once bitten twice shy I guess.

Just my personal opinion from the device half a decade ago, i believe these comments fit within forum guidelines.

This may have been a issue in the past or maybe it was a faulty unit. Who knows, you cant let a bad experience from years ago stop you from buying the best.

Otherwise we would not be driving skylines because Datsuns are rusty pieces of crap.

no mine is still going (less than 5000km's old)

but every 2nd person out there say there's was working one day and just stops the next. i don't even know if i got warrantee on mine.

i did have an immense amount of problem trying to calibrate and update it, and this problem still exists. i just worked around it.

i don't know if i should have gone LM1, PLX, or WB02 now. but i definitely wouldnt chose the LC1

Sell it and buy a WB02, you wont regret it!

How many hours as the sensor seen, how old is the sensor, have you checked it against a known good unit for accuracy and response time recently.

My sensor is 13 months old, and has been in my car permanantly for this time as well as being removed weekly to tune other peoples cars or check the afr's. at least 25,000km's

I have had my sensor connected while being on 4 or 5 different dyno's and have checked the AFR's. If anything my sensor is faster then all the dyno's i have seen.

And whoever said it had unessasry lag, how the hell would you know if you have not compared it to other systems yourself ? I am one to never listen to what anyone says about something or be skeptical untill i see it for myself.

I can assure you all the wb02 is great, i just got a call from peter, he picked up that my unit had the wrong firmware, he fixed it for me and confirmed my cable is faulty. He is going to fix everything up and send it back to me the SAME day as recieving it.

Id love to see any innovate product get that kind of support. Looks like now il be able to do the road tune on the 180sx on the weekend if australia post get it back to me on time!

Good response Guilt Toy - thanks!

I think you may be correct, older units mighta had some bugs. (Id heard of another guy that experianced bugs too... though thats 2nd hand info)

Will wonder down there and have a chat with pete, truly would rather support a local business :P

We tuned mine using the innovative gear and it matched the dyno afr.... guage is good for the worriers, every opportunity i get on wot i have a quick glance to make sure afr's are holding steady.

The egt gear is even more valuable imo, just needs to be logged and looked at later (no point looking at one channel of data, egt is only useful for trimming individual cylinders by comparing all 6 at once)- but an excellent tool for the tuner to use when on the dyno and also for the owner to check what the tuner has done and also keep an eye on things under varying conditions and over time.

I hate all things electrical yet still installed and wired up the innovate o2 sensor, gauge, egt's etc very easily, worked first go no problems at all. And havent had a problem since. Mind you I located the LC-1 in the cabin.

As for sensor location, I was advised to put it halfway around the first bend in the exhaust.

Cool!!! I just heard back from techedge and they are sending me a brand new cable and sending me out the gauge so i can have EGT & AFR reading at once at all times...

Cannot wait to get all this setup! be interesting to see what my egt's are

Well if I can just run the o2 sensor from the stock o2 hole as SK said he does. I might just do that for now.

I did my first datalog and everything seems to works really well, my afr's are dropping into the 9's!! (stock computer bigger turbo/injectors(pfc died and is in japan getting fixed))

lm-1 manual just says after turbo & before cat, also states 'The maximum temperature of the sensor at the bung (the sensor hexagon)

should not exceed 500 oC' I might get infa red temp gauge from work and see how hot the stock o2 gets (not sure if it read that high though).

Edited by SevenAngryPenguins

love to know how you keep exhaust gas under 500o. my gauge was showing 750o the other day and the 02 sensor is within a foot of that. If it looses 250o in 1 foot then it came out of the turbo at 1000o lol

I will be interested to see this guage.

I recently purchased the WB02 3A2 unit after being reccommended it by a couple of reputable tuners in melb and us.

I am very impressed with its response and features for its price.

how good!!! tech edge package waiting for me at home.. what awesome service. the wide band unit was out of my hands for 2 days while getting checked and upgraded FREE of charge.

Cannot wait to install my new gauge !

your making me think I brought the wrong product now :wub:

Anyway ended up sticking the sensor down where intercool did, the weld was a bit messy but it didn't cost me anything.

um we are discussing narrow band vs wideband here...widebands are very different beasties...

yes good point

if you are worried about exceeding the recommended temps for the o2 sensor check this one out

http://www.innovatemotorsports.com/xcart/p...at=0&page=1

I dount many will have a problem though, the lc-1 will display an error message when the temps are exceeded (700degC gas temp or 500degC material temp). Mine is less than 12" from the turbo and I am yet to see an error message.. cylinder egt's all peak at 900degC roughly 1inch from the head if thats any guide (530rwhp and 10.8afr's).

Have to say the innovative is a good looking gauge as well, and easy to mount being less than 15mm thick.

    • Did this end up working? Did you take some pictures?
    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
