Anyone here got one and if so how well does it work for you? There are so many different types but word on the street is that cheap ones are inaccurate (makes sense).

I'm looking at Innovate MTX-L wideband kit with Bosch LSU-4 which comes with data port for logging as well.

It can't stay for long on a 2 stroke because the oil will kill it in short order but it should make for a good diagnostic/jetting tool.

So back to the original question: Anyone got one and of so what make and how well does it work?
 
I've been thinking about picking one up, too.

I have my eye on this one, at the moment:
http://www.frsport.com/Innovate-Motorsports-3844-MTX-L-Wideband-O2-Gauge-Controller-kit_p_21255.html?gclid=COmBqdr89LMCFWlxQgod8DwAXg

As a side note, Bosch says their sensors can be used on a two stroke for a short period of time and then "cleaned" by using it on the four stroke, afterwards. Sensor life is meant to be about the same as a set of plugs.
 
Never had one on a bike, but on my cars I used Innovate lc-1 and it made tuning super quick and easy, no more guessing. Plus the kits are super cheap from them but work perfectly. No idea about 2-stroke, but on my cars I ran the same sensor for atleast a year and a half between two cars. Having wideband results always at a glance is awesome though.
 
Thanks guys. I'd really like 3 x O2 sensors and full suite of Innovate gear with data logger and EGT x 3 but that's just a winning Powerball ticket too far away this week.

Matt, that's the set I ordered earlier this afternoon. 2 strokes and high lead race gas tend to shorten sensor life drastically but this isn't a closed loop ECU, it's a diagnostic tool to check mixture that the dyno doesn't help with, so that's not too much of an issue.
 
Used their LM-1 handheld meter to tune cars. Our dyno had wideband o2 capability and both were on par. Good product

Do you plan on welding in a bung or just using it temp with a clamp on the tailpipe?

Weld in. Individual pulses are so strong on each pipe that they suck so much air back in that it reads lean (false). I'll weld it just after the collector on a 3 into 1 to get mid rang fueling right and then bolt in a plug when it's jetted right.
 
You've got me confused teazer!

Your initial post mentioned two-strokes but the last post says 3-into-1; what is the gauge being fitted to ?

Crazy (and puzzled)
 
I've got one, I used it to tune my cb750, works quite well, as the sensor is really the critical part that gets the accuracy, they're all made by a couple companies, none of which are "cheap" afaik, the gauge unit is probably the cheap part, but that just reads out the info from the sensor... best I can tell, it's dead on, I did about 5 carb rejettings after installing it, and got really useful data. I got a major dead spot to almost completely go away (accel pump crap), and now the bike runs just about 12-1 on accelerating and 15-1 cruising, there are maybe 2 little spots at certain loads and rpms where I can't seem to tune it perfectly, but I think that's more to do with the carbs than the meter, it's made the bike way more enjoyable, really kicks ass when you open it up, and saves a ton of gas when you're just cruising

Both. It's a three into one on a two stroke :)

Innovate uses genuine Bosch LSU4 5 wire sensors, and have a reputation for being among the better products
 
I've been using the one from PLX for about 5 years now,
modified it to supply rs-232.

Where exactly do you put the fuel/air sensor? Right behind the carb? Do you have to drill holes in the boot..?

It's a Strader designed by Walt Strader who had his own company for a while and later on became chief designer for a larger company. He holds a patent for multi tube baffle design.

Ronnie, It's an Oxygen sensor that reacts to the level of unused oxygen in the exhaust. The same sort of O2 sensor in a car exhaust only this one is tied to a gauge and not to the ECU

it's actually a wideband sensor, the sensors used in cars are narrowband, which are cheaper, but give fairly unusable readings anywhere to the north or south of 14.6:1
 
Dobeck Performance makesa Wide Band kit for bikes now. They are the original designers of the Power Commander.
