I think you will find the time it takes to development an indirect home built EFI system for a 2T motor, will be considerably longer than anything related to 4T.

Reasons for this is due to the difficulty of accurately measuring the negative/positive pressures in a 2T crankcase, which are linked directly to atmospheric conditions and temperature, and is the main reason nearly all commercial 2T EFI systems are direct injection, even though this is much more complicated and costs more than port injection.
