I would prefer a digital gauge too if im honest, and im told they are looking into producing optional front end units, one of which will be digital

But the fact that it sweeps around being a problem is the same as saying you cant read a fooking boost gauge

On top of teh above, the fact it has a programable warning light means i dont give a toss what it says anyway as a driving aid...

I cant comment really as the 540+vat NTK sensor im using with my ECM unit updates at 5hz so ive not seen a problem with them personally

Also, its a mute point as the unit under discussion is supplied with a Bosch LSU4 so end user chioce is not necessary.

Finally, yes, ALS and unburnt fuel will kill a lambda sensor in very short time.
