I am upgrading my fuel system with 720cc. What else do I need to make it run right with larger injectors. Will the apexi SAFC II compensate the change or do I need a chip?

on stock twins?

 

[BlueSteel]

no I already have installed a t60 single and I'm currently running with the MAF sensor still on.

Go MAP from MAF. MAP ECU or VPC or standalone (AEM, Motech) Get fine adjustment fuel control if you go with the VPC.

Get a 4in air intake. Tune to 11.5:1 AFR from 4krpm to redline.

Get 100 octane or better and turn up the boost.

I'm on a budget and I wanted to know do I need all that or can I get by with the SAFC II?

you can play with the SAFC, but that MAF will only flow and meassure air till about 550rwhp

then you either need a second MAF, PHR MAP ECU, VPC or AEM

you dont get fine adjustment fuel control with a vpc...they only let you take out X% of fuel from the whole rpm band...you need some kind of additional fuel controller (afc or gcc or afr) to get good control.

if hes asking this question (unless theres a really good reputable tuner in the area) i would say any kind of standalone is a little to advanced....pretty much anyone can tune with a afc/vpc combo and its proven to work great.

so basically I can rig up a pipe with two MAF, upgrade my injectors and fuel system then run just the AFC II to lean it out a bit.

dude, that's what I meant. the vpc is course adjustment, the fuel controller is the fine adjustment.
