Ok tomorrow im putting in my safc-1 , 550cc inj, and z32 maf. I am going to trailer the car to get tuned, but it would be great if someone with these on there car could tell me what i need to set stuff at to get it running decent enough to drive it on the trailer and the dyno and what not. Ive heard i need to set something to number 2 or something for the maf to work with the car? Could someone please help me out. Also does anyone have the wiring diagram or where to get it for the s13 redtop ecu, because the one on apexi site is for the version 2 and not 1. Any help would be much appreciated

 

I would just get a retuned ecu for the injectors and MAF. While you are at it you can remove your rev and sped limits.
From what I've heard you cant tune for the 550 inj's because thats a gain of 53% and the SAFC is only capable of +/- 20. The SAFC II is capable of +20/-50 if I remember correctly. If you have the SAFC II you ay be able to get it close depending on your car.
