Re: Catalytic converter

[Darren_Mason@xxxxxxxxxx]

>>Eric,

I live in Colorado but picked up my Speed Triple in Los Angeles, and I was
told (and my research seems to bear it out), that the vapor recovery
/charcoal canister and the "catalytic block" are the only differences in
the
California models versus the rest of the U.S. My dealer here said that
there
is no difference in F.I. tune for the California models, and that by my
adding the "race can", I pretty much eliminated any performance penalty
that
I might have had.  I believe the catalytic block is located in the exhaust
header and that you would have to replace that component in order to remove
it. I think all this is the same for ST's as well.

Chris,
     According to the workshop manual, models with a catalytic converter
also have a lambda sensor in 1 header & different maps in the  ECU.
     If it is the same as cars, the lambda sensor provides the ECU with a
signal according to the mixture strength & the ECU finetunes the mixture
accordingly. This usually does not operate at high load, where no feedback
from the lambda sensor is used BUT this is changing as wide band sensors
become more readily available.

     Darren.
