I just need a wideband O2 sensor and the Tech Edge has been recommended.

Clicking on their site and I'm blown away by the product range http://wbo2.com/

As the sensor will not be living in the car beyond initial setting up and a possible session on a rolling road I feel I don't even require a dash gauge.

So, my question to the brain trust what do I need for my RV8 with Megasquirt 2 from this range?

I'm tight, so please keep it cheap.

2j2 is ok if you are happy to set it up on one bank only or move it when you need to look at the other bank. If your on a single throttle plate as opposed to ITBs then this one is fine as you can't adjust the banks separately anyway and they can only be different if you have a major air leak or dodgy valves/injectors. The 3H1 is dual but expensive and Megasquirts only support one wideband anyway. I use the 2J2. You can get them from a UK disty www.trigger-wheels.com and he holds stock, ordering from Australia gets pricey as they sting you with import taxes etc when it lands in the UK. Innovate units are cheaper, don't buy one unless you want a string of warranty claims and then end up buying a techedge anyway.

OK Jon on the 2j2.

The plan is to locate the bung just behind where the two manifold collectors merge.

Is this ok so far back?

The last time the car was on the rollers at Austec they measured 276 at the wheels however the reason for the MS is to smooth things out and hopefully gain a little improvement in the mpg department.

Thanks for your comment.

No thats NOT true, MS can work with any wideband that gives an analogue 0-5V output, the same as every wideband I've ever come across, even works with narrow band lambda's.

Where did that miss information come from???

I couldn't grasp if he was intimating only one kind of Wideband or only a single (rather than dual) sensor, either way it was false AFIK.

Misunderstanding here. I meant only one can be connected not that they only work with one kind or brand.

At the collector is fine btw. The gasses move way faster than a cheap end WB responds.

Thats not true either!!

MS2 and MS1 can run a pair and use them to tune each bank.
MS3 can have 8 connected to it and run each cylinder.

Love to know how, I'm sat here looking at one and see only one input. I assume you mean it can be made to with one of trhe MSExtra firmwares? If so which one as that would be dead handy for getting my mini turbo to keep it's AFRs equal.

I thought I better check my facts. I was fairly sure I was right anyway having used them for years.

NO, MS1/2 can not run 2 egos, they can be modified to run 2 EGOs. Nit picking maybe but it is hardly fair to say they can when as manufactured they can't. With a bit of soldering and the addition of a few components and MSExtra firware they will handle dual wideband or narrow band sensors.

Using the same logic wouldn't that would be akin to saying they can't manage coil packs either then?

The extra components & work to support a second O2 are actually a lot less cost & effort than adding sparks IME.

Microsquirt will, MS1 and MS2 will not without either adding the ignitors or using external ones so yes, quite logical and quit correct. In the same sense that my TV will not play DVDs, unless I buy a DVD player. Sorry I just don't see the logic of your post at all. I'm sure a megasquirt could brew coffee if you wrote firmware for it and added the hardware but are we to believe it's also a coffee maker.

I feel quite happy snipping the pins on the cpu, cutting tracks and adding extra components to adapt it to what I need it to do. Others may not and to incorrectly assert it does these things when as supplied it does not is misleading and unfair. If someone tells me an ECU supports dual EGOs and coilpacks and I spend £300 to find it does neither when it arrives I'm not going to be too chuffed and telling me to get out my RS catalogue, soldering iron and strongest glasses is not going to make me much happier. Don't get me wrong, I love using MS ECUs and have been using them for many years but they are not for everyone. Folks who are not comfortable with electronics and delving into the depths of how every last sensor, signal and semiconductor on their car works "may" be better of getting another solution.

To look at it differently, I guess if you asked Phil to supply one that could run 8 sensors then it would arrive capable of running 8 sensors.
