I know you are going to say search but I did and way to many posts came up that were leading me nowhere. Maybe this is a good post to refer those that are unsure or unaware like myself. It may even be worty of a sticky in the ECU forum.

On the techedge page it says that I can buy a prebuilt kit: "V 1.5 WB Unit - just the TE-WB 1.5 unit with data acquisition cable, NO display (see below), and NO sensor cable (see below) @ AU$260 "

Is this all I really need other than the sensor and sensor cable?

Does this come with a connector to plug it into the PFC or do I have to make it or special order that from them? (It does come with a data acquisition cable...will this work)

Does a wideband take the place of an O2 sensor? (if this is the case I can use its bung and if not do I have to add a bung in the DP)

If it does take the place of and O2 how do I splice it into the stock O2 sensor wires or do I have to?

Thanks for any help you all can give me.

A wide band needs its own O2 bung. Personnaly I'm gonna get a real motec wideband (when ever I can get enuf guys near me to chip in for one), why risk a 2-5k engine/turbo/s on a 400 dollar product when the real thing cost 1k? To me, 600 bucks is not worth the hassle... but thats just me.

Some things you can make/mod yourself and somethings are better left up to the professionals

good luck

You should check out the FJO wideband. It comes in a variety of packages with different options and pricepoints. I think the cheapest package with a display is about $650. There are packages without displays if you are hooking up to a datalogger or computer.

You can also just leave it in all the time as the 02 sensor is rated for 30k miles with unleaded gas.

I will be going this route when I get a wideband.

You need display to view it real time. I think you cannot view it realtime with PFC Datalogit.
O2 is around 135-150 $
Bung is cheap size M18
Welding is cheap too

True, but I don't think you would need a display for tuning purposes, it would be too hard to note the A/F ratio (since it's changing constantly) and rpm to any usefulness. I would think you would only use dataloggin for tuning, ie, datalog each run.

I also don't think your A/F is something you need to monitor constantly once your tuned, so again, I think a display could be considered optional (but nice to have).

I have my DYI wideband and it has the output for the data loging. I have not received the datalogit but was wondering how the DYI wires hook up the the datalogit also? Do I need an adapter plug or is it simple? Also are You guys placing the O2 sensor in the midpipe or further back?

i have the FJO and welded bung in the begining of the midpipe. i am using a haltech so anything about the pfc is greek to me.

The new version 1.5 will have a narrowband simulator. So yes, with 1.5 you can do it.

Why trust your car to it? I have gotten my unit built. Not in the car yet. However, nobody has said it does not work. And it does not work accuratly.

The kit does its job just fine. Some times it does not take more money to get the job done.

I asked the Datalogit folks about various widebands, and they recommended the DIY from Tech Edge. I've got the full pre-built package on order, and should be receiving it soon. My Datalogit is still on order as well.

One thing about the DIY is that the sensors are hard to find. Both NAPA and The Parts Bin cancelled my orders because the sensors are on "national backorder". I think I managed to stumble into a deal to get one though, but I won't know until next week.

There's another wb controller called Lambdaboy, that has an output which is claimed to be able to replace your stock O2 sensor for the ECU. I almost ordered one of these, but the fact that I couldn't find anyone using it with Datalogit made me get the Tech Edge instead.

I'm looking forward to getting mine all set up, but it won't happen for a couple weeks.

If you go with the Tech Edge, find a sensor before you order it, unless you don't need it any time soon. My other source fell through, and I was left with no immediate hope of finding a sensor, so I ordered an FJO instead, and told Tech Edge to cancel my order. Unfortunately, they've probably already shipped it, so I'll end up selling it, or sending it back.

Good luck,

I went with the TechEdge wideband kit and it looks fine to me. I know guys that are pushin 400+rwhp and it's the exact system they use. Whoever doesn't think this kit is any good cuz it doesn't cost that much obviously has not done their homework. ANY quality kit is going to use the NTK sensor, which is what the TechEdge system uses. If I'm not mistaken, the Haltech uses the same exact sensor but they charge like 3 times the price you can get it at Napa for. Yes, the sensor can be hard to find, but my local Napa store rep was SUPER cool and he did a little search for me. He found 5 Bosch sensors in one day at various store locations. When I opened the Bosch package, inside I found (well-ah), an NTK sensor!!!

IMO, as long as you use a very high quality (accurate) sensor, any of the systems out there are gonna be neck and neck with how they translate the sensor info.
