Need help setting up SAFC II with 550cc injector?

[drift_ricer]

I just installed Z32 MAF, Sard 550cc injector, and Sard FPR. I don't know how to putting percentage into SAFC II. My car start, but sound choke for about 5 second, then off. please help?

try starting at -33%.

[trybal]

yup.. i think mine are at -30 for 800rpms.. then slopes down to about -16ish at 3500rpms.

thats for partial throttle not wot

but untill you get a wideband on it i suggest you stay out of boost

I am new about the safc. where do I input those percentage? thanks

[trybal]

af corrections.. theres a high throttle and a low throttle setting.

[drift_ricer]

so I set the high throttle -30....what's about the low throttle setting?

[trybal]

no no.. what i wrote in there was the low throttle.. download a manual for your safc stat. also, there are a few threads on here with better setting readouts for the same setup you have. And it differs car to car so you really need a wideband gauge

Dude, before you go messing around changing %. You need to know why first. The injectors are about 33% bigger than the stockers, so that is why you -33%. As far as low-hi throttle settings go, you need to figure out when (what rpm or throttle input, I forgot) you want the afc to switch between the two 'maps'. So -33% on low will get your car to idle and run almost like stock so you can go to the dyno or your buddies house to hook up the wideband that trybal was saying to do.

Now, that will only work if you set the afc to the correct in-out for the z32maf.

Play with the afc with your car on but not running so you get familiar with the settings, so you know where to start plugging in % and in-out settings.

Hope this helps

the in out setting you need are. 6 in ,1 out
