SAFC-II seting problems.

[Nicksemianiw]

Ok well i put in a SAFC-II and 550cc injectors and a fpr. I got the stock mafs and the guy who set it for me might have done it incorrectly. Now i have no idea what to set it to. For stock mafs and 550s what settings do i change? FYI Never had a safc-II before lol.

Check the settings for the air flow meter. A stock S13 SR20DET MAFS should be 6 in 6 out assuming you have an S13 SR, or 5 in 5 out assuming you gave an S14 SR.

The SAFC2 was not made to run different injectors properly but most people just go into the setting mode and turn up the Hi and Lo throttle settings to plus 50% across the rpm band.

Yea so i got a crack in my sending unit lines right where it goes into the sending unit i put a filler on to try and seal it. And i have a adj fpr and the PSI went to 65!!!!! Could this be my problem why its boging and runing super rich?

Also is it 6 in 6 out for the sohc mafs?

Probably since its interchangable with the S13 SR MAFS. The Apex manual does not specify.

real risky running that big of injectors without some kind of rom tune/stand alone.

I suggest getting a wideband or dyno tune ASAP, I would start with the lowest percentage you can go on the high/low settings first and work your way up from there until you can get it tuned properly.

Yea i am going to get it runing then get it chiped and get some dyno time.
