    Fuel and injector parameters affect AFR.

    I have seen an injector parameter on the size the stock tells me that it is 16.5 lb / h when I raise it to 18 lb / h I imagine that I cheat on the ecm saying it is bigger and as a consequence it will affect my afr that I made richer mix or I will be in an error

    Fuel injector flow rate changes are OPPOSITE.

    16.5 lb / hr to 18 lb / hr AFR is consequence leaner.

    16.5 lb / hr to 15 lb / hr AFR is consequence richer.
