On boost or off boost?
I'm not sure what the "perfect" AFR/Lambda or "running rich" would be, it different things to different people
I would say mid 11's on boost would be "good" depending on the EGT.

Gonna depend on spec and personal preference.
Some people say 12s are fine (seems daft on a turbo car).
Most say somewhere in the 11s.
Some cars run in the 10s and seem to be best there.

ah ok. So no real set rule then. I was told my car is running very rich, and knocking the power out, so bought a wideband and gunna stick it on to see what happens.

problem is boxxer, even if you do find it rich, yuo've got to take it to a pro to get the map adjusted.
that pro will have his own wideband.
just seems a bit of a waste of money for the purpose you want it for.
if you wanna keep an eye on things for safety, great![Top](https://passionford.com/forum/images/smilies/smile011.gif)
if you want something to use to DIY map, great![Top](https://passionford.com/forum/images/smilies/smile011.gif)
if you just want to diagnose a fault, Ł300 quid is quite a bit of money

Lamda 1 is the term given to STOICHMETRIC MIXTURE or 14.66:1, ie 14.66 parts of fuel to 1 part air, generally termed 14.7:1 as this is close enough.
This will NOT however give you MAX power for this a RICHER mixture of around 12:1 gives most power, some that go richer may be doing so as a safeguard, as this lowers the temps in the chamber.
Turbo size totally irellevant to MIX strength, it is the cobination of boost(air) and fuelling that determine these.
Anything below 14.66: is rich, anything above is lean.
Running a richer mix will result in better or increased MEP mean effective pressure.

i assumed you were talking about the cossie
ke-jet has limited adjustment on it, you wont really get it perfect everywhere, a lot of it is compromised. works fine on standard engines, but when you start modding stuff the standard system struggles somewhat

Can you fit a wideband Lambda sensor in place of a normal one on an Escos, and split the signal between the ECU and an AFR meter?
I would like to keep an eye on things!
