yes no problem
You have an example?
e-mail a file, we see
I read this discussion and I asked myself what is the need? all this, in the world of two wheels these things are from so long xch? usually you want to change the exhaust and in some of them ? necessary to remove the probe or probes xch? in the dashboard remains the malfunction indicator light on,many times it is deceiving with resistance at other times, the supplier of the exhaust comes with an emulator,in the meantime, let's start from a premise:
The lambda probe ? need to know if the exhaust gases are fuel, non-combusted, to maintain the mixture ratio (kg air/kg fuel) within the range of optimum efficiency of the catalyst, better known as "lambda 1".
Primarily maintains the mixture of air-gasoline pi? lean to work well with the catalyst and limit emissions at the exhaust , it seems to me that this is not you ? spoke to xch? if I understand it is not about changes at the load, instead with a drain to open its function can? be deleted in accordance with? a programming of the control unit, which maintains the stoichiometric ratio pi? brought to the performance and low emissions... the behavior you describe I suspect that the ecu is working in a kind of "mode? protected", not by receiving information from the lambda probe automatically uses a preset curve so perhaps very conservative, or perhaps it uses the last good curve stored in the memory. at this point I wonder! what is all this if not do not c'? the intention to remove all the catalyst? I can also illuminate x to my knowledge?
if you break the probe downstream of the cat, and the customer does not want to spend money to change the excludes and many greetings.this is the only utility? this operation
excuse the magi, I had not thought of this last solution how to use?,I do not do this work as a profession, and then there will be? ever have a customer ask me this I speak only in technical terms, but at this point there are so many alternative remedies as I had said before.

The second probe only controls the operation of the catalyst is not involved in the determination of the maps if not when it goes into recovery.
however: the open loop = open cycle = probe not considered
closed loop = loop closed = feedback control of the probe
But of the upstream...
To confirm what I knew too, but from what I read I seemed to have understood that it was possible to eliminate the probe before catalyst ? directly involved in the fuel mixture.
sar? can also.... the ECU will manage? the fuel mixture as if the probe was broken/detached
Clearly it's better for most uses!
but then the 2 probe, you can disable it from the map? I have a friend that would want to remove the kat but the probe 2? how do I disable?
