CF MOTO 450MT AIR FUEL TUNING ON DYNO

[@crj7218]

Me like desde España 🇪🇦🇪🇦, cuanto hp da entonces 52cv?

[@veljko866]

44hp at the crank. Nobody ever shows figures at the wheel except the dyno. Now, the torque is a lot lower, are the sprockets changed?

@@veljko866thanks for your comment, yes, every 450mt users here change fromt sprocket plus 1 teeth to make the rpm revs go slower and more calm

does afr tuning decrease fuel consumption on 450 mt?

[@ficlinic6388]

@@robertdelacruz7920 Not really, it just maximizes the output that the fuel gives out into maximum power and smoother ride, these cfmotos are already tuned lean at the factory, I added about 5% more fuel on the RPM range that needs it due to inconsistent fueling caused by the pipe modification, PS just by installing aftermarket exhaust increases fuel consumption by 5-10% if not tuned

@@ficlinic6388 If I change an air filter and a better performance OEM exhaust, without tuning, it will increase the air flow and the ECU will correct it by injecting proportionally more fuel (14: 1) approximately. If I tune the ECU to 13.5:1 it will increase fuel consumption even more than without tuning. The EURO 5 standards limit the manufacturers to tune the engines in a stoichiometric zone which is not good for the engines. It is always healthier to work between 13 and 13.5 :1, better power response and lower combustion temperature. Very nice work, it would be necessary to tune the 450MT with exhaust and OEM filter to see how much HP it gets. Greetings from Argentina
