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...
Ask a question, start a discussion or post something for sale!
