I am currently in the planning phase of upgrading my turbo system. As many of you know, I have the Cartech system which uses the Rebic auxiliary controller. Others had problems using this system and I'm also concerned that the near cylinders are running rich and the far cylinders are running lean. Of course, this results in a reasonable A/F ratio when averaging all of the cylinders but I am worried about long term issues even when running low boost.
My plan is to go with the HKS Pro FCON since it reportedly can be used with an OBD II car. Questions: Should I go with larger injectors and if yes, what size? Should I upgrade to a bigger fuel pump? Is a wideband O2 sensor and A/F meter necessary? Can I use cat bypass pipes without tripping the CEL since I am using a separate ECU? Any help would be appreciated.
