Ok, right now, I have NO FUEL MANAGEMENT hooked up on my car. I have: Greddy E-Manage, RC 450cc saturated injectors, and a B&M FPR. How should I go about tuning all of this once it's installed? Do I tune the E-Manage through a Laptop, or do I need a Profec or a Super AFC or something? Do I need a wideband O2, or is the stocker fine? And also, will I need a Fuel Pump and/or Fuel Rail?(Stock HF FP and stock LS rail right now.) And lastly, what should I do about the MAP sensor? I have a Missing Link, but it's for cars with the MAP attached to the IM, and mine is connected by a vaccuum line. Any advice is much appriciated! Thanks dudeages! EDIT: Here is the setup. Stock B18A T3/T4 .63 A/R .58 exhaust HKS Wastegate Greddy Type S BOV Stock Fuel System EXCEPT a B&M FPR Stock O2 Automatic LS ECU OBD0 And I have E-Manage and RC 550cc SATURATED injectors uninstalled. I don't know what else you guys need.
