PLX Devices Wideband AFR System - anyone used this?

So a guy at my work suggested I get a wideband aire/fuel ratio sensor system from PLX Devices.

Has anyone used one of these before? It looks pretty sweet and I'd love to be able to tune my carb perfectly for a change. But, I currently have and want to maintain having true dual exhaust. Seems like I would have to get 2 of these for that. So I thought I'd see if anyone else had used this or had a suggestion for a similar product.

 

I have an Innovate LC-1. Unless you're running a single plane intake with a divider you only need one sensor as each engine bank is supplied by both sides of the carb.

 

same here, i use the lc-1

 

Hey thanks guys. Learn something new every day.

Going to have to do some reading on how carburetors actually work I guess. Never really paid much attention.

 

The gauges on that company's website are wicked! The dual function ones would be great for a custom gauge cluster. Alil pricey compared to old fashioned...

 

The company is in my area and I have seen a number of people use them. I have friend with a 32 Ford and it drove me crazy while driving his car....but it does work.
If you do get one do yourself a favor and get two sensors as the gauge will support more than one sensor. There is a reason both chassis and engine dyno's use one sensor per side..................it's the only way to tune the engine for max efficiency.
Remember that the WOS only looks at unburned combustible content in the exhaust and AF meter converts the signal. AFR changes from idle, part throttle and WOT. Most WB sensors will measure from 9:1 which is extremely rich down to 19:1 which is extremely lean. Also realize that an WBAFR can give false readings, such as at idle and low engine speeds with a long overlap cam, exhaust leak, backfire/misfire and on supercharged motors at low engine speeds.
When we first put my motor on the engine dyno the right bank was running rich @11 and the left was @12.48.............after 12 pulls (and a lot of jet/timing changes) we were at 12.47 on the left bank and 12.58 on the right.
Without both sensors we wouldn't have been able to get it that close.
Of course this is on a race motor and for a street motor it's 6 of 1 and 1/2 dozen of the other...............it is a great tool to have in your pocket...IMHO

 

Thanks, quite informative and confirmed a lot of what I suspected. I figured buying 2 would be the best, and it's nice to know the gauge supports 2.

 

Innovate LM-1 's here

 

I have the FAST one, plain dial gauge, not nearly as pretty as yours. Works, and like said above, it drives me CRAZY watching that gauge go rich while I accelerate. I took it off, but keep it around if I want to get to tuning again.

 

I run a AEM wideband, priceless tool imho

 

My car is mostly a drag car now so for my application I would be lost with out it. I use the LM-1 to data log Lamda/AFR, RPM, Trans Temp, WOT, Fuel pressure.
