{ Also, a Mass Airflow Sensor is not needed for fuel injection. Fuel injections systems without a Mass Airflow Sensor rely on a MAP sensor, (Manifold Absolute Pressure), to supply needed info on engine operation in order to supply the correct amount of fuel to the engine.

And lastly, high fuel pressure is not needed. A port fuel injection uses high pressure, usually somewhere around 40 psi +/-. But throttle body fuel injection only needs 9 to 12 psi for most systems.

Having said all that, I think this new system is cool, and hope it filters down into the hands of us poor boys someday soon! No engine is harder to supply with a perfect fuel mix than a two stroke, and fuel injection would be great to have. Especially if it were user tunable.

But you do require one are the other. You have to have a MAP sensor at the minimum, without one the engine will not run with fuel injection or throttle body. You are right about the O2 sensors, cars run all the time with them disconnected or broke, but a MAF or MAP sensor is

required. And if it requires at least 9-12 psi where in our free flow tanks are we getting that. The engine does not look to have a pump. I think it is neat but not really a need. What is so hard about tuning a 2T engine?
