Change Operation Lambda

[Metropolis]

Hi guys, I wanted to ask you one thing, hoping that what I want to do is possible, and not only science-fiction, they asked me to change the operation of the lambda or better to modify the report stechiometro on which the work of the lambda, I'll give you an example, the lambda is working to keep the relationship stechiometro that varies from 14.5 to 14.7, what I have asked of me ? to be able to raise the value for which to work with the lambda or better to bring the threshold from 14.7 to 13.5 in order to be able to keep the lambda without deleting it, and make the engine work at a relationship the most? fat. I really hope that you can find help, the ecu on which ask me to do there? are the Miu mounted on the piaggio group...Thanks a lot

I would say that I think your ideas are a p? confused about the operation of the lambda probe on a motor benza metropolis....
the lambda is not the work of the lambda law a stoichiometric ratio.
if you want to turn more fat your engine does not have to grease the fuel mixture by adjusting the required lambda driver in the map....
the first to do everything there? you have to make sure that your lambda can read AFR under 14,5-14,7....
then you should fit a wide band lambda or wide bands that dir you want and adjust the linearization of this in the ecu.....

I understand...abandonment, then this project why? honestly they asked me and I wanted to see if maybe it was possible, and I ask, maybe even something more? specific....or better to make the LAMBDA OFF and the STEPPER OFF on IAW15P...Someone can? help me?
