And also its running a little rich I was wondering what wouldbe the best thing to tune it with? vafc? safc? afc? Whatever. Can somebody help me out?
Dont put an s14 ecu in it,thats pointless. Put the stock injectors in until your ready to tune it,unless you can deal with the richness. Go on KA-T.org and read about the calumRT setup, especially since your s13 obd1 its easier to tune and you can fully tune it, instead of just doing fuel with SAF(ail)C. Also, you did swap your speed sensor+TPS those are really the only things you should've worried about.
