SAFC2 Setting

[Lucient]

I currently have a JWT ECU tuned for Z32 MAFS and 50# injectors. My engine(SR) has 550cc injectors. I want to get a baseline tune on my afc to make it to the dyno

I figured the 50# injectors to flow 510cc which is 40cc less or 7% than the 550cc.

Is is safe to set the safc to -7% across the board or did I do the scale wrong?

it wont be a perfectly mathematical difference.. best bet is to set -7% as your basemap (kinda lol) and read your wideband. btw, how did u get the # to cc conversion?

I got it off the web. I dont have a wideband. i just need to make it to the dyno without running dangerously lean or rich

well fire up and see how it idles, lean wont hurt you unless your in a high rpm / boost condition
