I was wondering if anyone else here uses this wideband and has weird readings from it? I am definitely not sure now about my readings, but the lambda should be preconfigured from factory and the only configure options possible are at the back of the gauge... I dont believe my car is running SO rich or SO lean (goes to 10 on WOT and high 12s on redline!) I have been doing many runs the past few weeks to test times using GTECH PRO RR, so I guess it would have already blown. Any suggestions?

do you get a reasonable 14.7AFR on idle and cruising up to say 3-4K unboosted?
What program are you running on your setup?
Wont blow on 10AFR on WOT for a few runs, there's pppl here running wrong sized injectors for months running mega-rich and still are allright
Post the GTECH PRO results on 0-400 runs please (I want to compare with mine )

Hi,

I'm going to get the same Wideband lambda in use in near future. I have the cable already installed from engine boot to cabin, now I need to power the gauge and install the lambda sensor into the downpipe.
I will inform my readings of it.

Where do you have the lambda sensor mounted? It should be at least 0.5 m downstream from turbo, not to be overheated.

The lambda is well past the turbo, so should be Ok...
I am really not concerned about the 10, I am "just" losing acceleration there, but the 12s concern me, I wonder if the 375cc injectors are just plain dead there, or if its the ECU self learning that is screwing my maps. On idle i get from 14.7 to 15.2 up and down constantly, sometimes though whien im slowing down and idle, it is at 16s and sloowly creeps to 14.7 ish again.

sounds normal to me tbh!
What's wrong with 12??? That's more or less where it should be, no?
I don't like the 10, bore wash, consumption and loss of power.
What chip you're running?

Its a custom chip, the problem is not 12, but mid to high 12s that worries me
