Yes your right it would need rejetting. My point was the cost to have a piggy back or program equipment. Also with 2 stroke fuel injection engines used today they are not close loop systems. That's what makes them so temperamental to mods. You can't run O2 sensors because of the oil in the fuel. The exhaust gases will kill the O2 sensor in about 15 hours of run time.

Austen, you would need a lot more than what you listed. Injector, throttle body with tps, not just air temp but air density and pressure. You need a fuel pump to supply fuel pressure to the injector and everything else I listed above. Fuel mapping from scratch wouldn't be fun. Again not practical.
