An interesting article in AMCN under Tech talk headed Measure and Meter regarding current fuel injection.
The last few paragraphs of the article read as follows >>>>>>>>>
This is all very clever,but it is still whats called an open loop system - basically a dumb computation of fuel metering according to simple sensor inputs predicting what will happen in the engine.
The finall tweak in the lastest systems is to measure actual combustion characteristics by looking at the amount of oxygen in the exhaust and fine tuning the fueling based on that.
Ii's easy to think of electronic fuel injection as a performance related innovation but, these days, it's as much about minimising emissions, maximising fuel economy and lowering production costs as anything else
So again despite what many believe ............ oxy sensors don't tune bikes .............. well not for power and performance at least
