For this application, practically any of them will do. The Innovate LC1 seems to have some heater control issues, which is why they sell that heatsink. Basically, they blame you for their shitty controller.

+1, and lol. its true, VW/Audi, uses that sensor on millions of shitty cars and none of them have a heat sink...

PLX AFR2 with DM6 is easy and cheap

we ran PLX back in the day, they were good, they are literally right down the street too, drive by all the time

what values can it.read.to.and.from ? I saw 11.6 to 17.6 on eBayin a pic but I'd think it has a wider range than that

on the other hand on a spec page I seen 10-20 which sounds normal.

what is lambda ?

PS. Thanks for your input, I like this widebamd and will probably get.it

Rotary > Pistons

PLX will go between 10.00 and 20:1 on petrol like most LSU 4.2 widebands

lambda is a representation of this in a form that doesnt care WHICH fuel it happens to be.. as lambda 1 = perfect air fuel ratio with no residual oxygen .. no matter what fuel

on petrol.. 10:1 represents lambda 0.68 ,, while 20:1 is 1.36

the same 0.68 lambda means 10.54 :1 in LPG.. or 4.35:1 in methanol

very few wide band sensors allow you to flip display between different fuels and lambda
.. if you flip or mix fuels then a sensible mode would be to indicate in lambda

even fewer have self calibration ,, and as hinted some brands have a "hard" warmup routine that is implicated in eating up sensors

the PLX has self cal.. and a "soft" warm up routine that isnt known to chew up the sensors
and the DM6 gauge can also display trend data .. also something you dont get in other packages at similar prices .. and bloody handy if you need to keep eyes on the road in WOT runs

True, but VW doesn't build anything with a turbo rotary engine, and that's the application where the sensor might need a heat sink and bung extender. VW also puts the sensor into a downpipe with a built-in cat and the sensor is pretty far out of the direct exhaust stream, not sitting on a thin downpipe after a firebreathing rotary. On my BMW race car the sensor is right in the headers near the ports and even after three hours of dyno time there were no sensor overtemp issues. Even on my prior NA RX-7 race car, I didn't have any problems and we spent even more time on the dyno getting it tuned.

With the BMW I've been running the same sensor continuously for more than two years and it was previously used in the RX-7 for a year and a half. So I would be hard pressed to call the LC-1 shitty.

Of course, I'm not using a display, the output just goes straight to the Megasquirt.
