Need help on setting the piggyback..

[adibk10]

To all sifu's which may guide my on this problem,

I'm going to installed 390cc injector(mitsu gsr) to take over my std injector 255cc(nissan march).But there's too much question on my mind including some bad explanation from foreman outthere.

I also have a piggy back(r-fit),quite same as safc2.

the question are,

1.can my car started when i start the engine(seem it will be to rich fuel mixture)
2.how to set the afc...do i need to set +50% or -50% to tipu my ecu to send low fuel from my inejctor to combustion chamber..
3.izzit the 390cc injector suitable for me or i need to find lower cc injector e.g 310cc...anyone have 310cc to let go??


p/s:dont said go to dyno shop to tune,coz if i installed the injector and cannot start due to rich mixture how to drive to the shop.

I think it's a Nissan March... the old superturbo one (as written in his sig).
