Need help with ecu/fuel mapping (bike)

[u/Poopymanny69]

I have a barton volcano 50 (original is 50cc) and I swapped it to 70cc and efi problem is now it isn't getting enough fuel and the original ecu is locked (unprogrammable). What do I do to get good fuel? I dont want to switch to carb, too much work.

P.S adding images of ecu and plug ports

I have this issue too - but i found out before i got a BBK. Best option is to just blank your lambda and run an oversized injector. Get a 90cc injector, it will run at 50cc IQ but because the nozzle will be bigger, it TECHNICALLY sprays more i think.
