If not you can do it manually as you ride for a bout $5 worth of bits..
Adjust the A/F ratio at the turn of a nob...

Here's best I know and what I understand be it right or wrong:
Yes that would work at below 6000 RPM, above that Delphi runs of its own map etc. Also the ECU would compensate back to desired AF even if you trick it into thinking the Air Temp is lower (self learning).
Funny thing is this EFI is even a bit better quality that is found on the GPX or PitsterPro which has a cheap DIY style Rojo EFI.
My RX3 and many bikes sold in China use Delphi as so do Briggs and Stratton mower and several other small engines upto 2 cyl.
If you look at the RX3 threads you get some more info BUT I haven't seen much about tuning the ECU and that I believe requires expensive gear etc.
No I never did anything with my RX3 ECU it is stock yet has a big bore.
The DLX has a Delphi made ECU but other parts are not Delphi made but compatible (maybe injector is Delphi maybe not)
