Im going to weld in a bung for my techedge wideband O2, was just curious about the best place for this, should I put it somewhere on the dump pipe, or somewhere just before the cat? I could use the original narrowband O2 position and get my wideband to simulate a narrowband signal, but apparently the factory O2 position is too close for a wideband.

I installed mine in the factory position and using the simulated narrow band signal back to the powerFC for close-loop operation.

From what I gather, the closer the better because there is no lag in readings. I know heat kills O2s but if you're car is running predominantly rich the O2 should survive.

Good point...

johnnilicte do you leave your wideband permanently in or once you finished tuning did you put your narrowband back?

Also how do i find out what the standard narrowband signal looks like so you could simulate it? or did you wideband controller do all this automatically? I think with the techedge your suppose to plot the points for the wide-narrow conversion (possible file on this already out there but I havnt looked)

I have left mine in for logging purposes, apparently the Bosch sensors are good for 80,000k's. They should be mounted no more than 12 inches from the turbo outlet according to the destructions.

I'm running an Innovate LC-1 with DB Gauge, I have it permanantly installed in the car. So far no dramas, have done 2000kms (I rarely drive my car).

Innovate LC-1s have 2x Outputs, 1x for Wide Band, 1x for Narrow Band.

Too hot.

They need to be in operational temperatures, but not boiled.

The good news for you is that the techedge/bosch combination has a heater; so you can pretty much place it where you like.

I'd put it a couple of feet back from the outlet; if that means "just before the cat" then that should be fine.

I have dramas with my innovate, as i believe it is too close to the turbo, about 20cm. Interestingly innovate sell a bung extender/heatsink to alleviate this problem.

doesnt every one :thumbsup:

ive got about 4 lc1's (2 wont talk to the programmer fk knows why) and 2 i use for V8's. My old LM1 seems to be the most reliable and is used for auto tune ecu's.

I get about 2 weeks from a sensor (my dyno uses the same sensor) bear in mind it runs 8 hours a day and gets hammered by vibration and sooty cars. The heat sink is cool and i use one for tuning alot of the jap turbo kits where the sensor is about 10cm's from the exducer.

I would fit the sensor about half way between turbo and cat, they dont like impact (rocks, constant water spray etc) so it is nice to have it up a little.

    • I'll tell her I put in a new air filter on it, which, it would have anyway with the ITB's In the end she isn't to fussed, she spends lots of money on hair, nails, make-up and all the other "required" beauty products that women use, plus I grease the wheels with shiny gifts and holidays wherever and whenever I can She once questioned my car spending "budget", but after itemising everything she spends on herself, and what I spend on her, and the fact that I don't care if she does or doesn't wear make-up and fancy pants perfume, or requires new outfits for every wedding, funeral or anything else she deems worthy, and I'm quite happy to go "real" camping, instead of staying in hotels or jaunts on cruise ships, she decided not to press the subject on how I spend funds, and has never asked "how much did that cost" again, so a win to me And how often can you say you really get a win with the fairer sex? She is a good woman, and in the big picture, I'm really lucky.....that she hasn't killed me yet
    • What will you do when the Minister of War and Finance says the intake noises are too loud?
    • Will the clear coat dissolve the ink tho?? I thought about clear vinyl tape too. Thinking what to do haha. The one I have now is cracked in 1 spot, otherwise mint. Plus the MINES one is much thicker plastic material so its not flimsy at all.
    • No. Go a different colour, and just trim it at an edge line. Even manufacturers do different panels different colours etc.
    • I see no real downsides to ITB's, apart from the initial cost of my drive in drive out lifestyle, the "upsides" is they sound cool and would add lots of smiles I am willing to pay to play for the extra smiles I've spent the morning googling and youtubing the BBR ITB's, a "little" extra power and throttle response, but alot more dort, and really, I'm only really in it for the dort Who knows, after all this money is spent I might even make 150kwatw....LOL
