Both run great. I did the conversion on the EX250 in 2009 and the GSF400 in 2013.
This past spring/summer I dug back into the EX250 to upgraded/improve the fuel injection (and ignition control) because this bike is becoming my younger daughter's ride now. This was both a desire to make sure the bike was up to spec because it's my daughter (right?) and because I enjoy tinkering in the garage.
So I improved its fuel delivery system and I implemented full ignition control, the most important item in this was adding the alternator rotor from a 2015 EX250 (this new-generation rotor has a "24 minus 2" trigger pattern on it, which works perfectly with the MicroSquirt firmware and it fits perfectly on the pre-gen EX250).
Other parts in the FI system:
ECU = MicroSquirt V3
Throttle Body = from a parted-out European 2008 EX250 (the first FI EX250)
fuel manifold in place of original fuel petcock = Pingle FI manifold
fuel pump = Honda TRX500 Rancher (four wheeler) fuel pump
Manifold Absolute Pressure Sensor = Motorola MPX4115
Intake Air Temp and Water Temp sensors = General Motors (AC Delco)
Wide Band O2 sensor + sensor controller = Bosch sensor + Innovate LC-1
Upgraded Fuse Box = Eastern Beaver PC-8 Fuse Panel
