It depends on what year you have whether you can use the STi ECU. It really only works easily on a 2004 5MT.aph626 said:What do i need to do a sti conversion for my fxt? I already know i need the tmic, turbo and ecu but what else?
The 04-05's had the same 55occ that are used in the STi, so no they arent needed.aph626 said:And the injectors too? thanks for the help
Not in my opinion, other than maybe passing emmisions with a catted DP. The Cobb map may also be good for more power from the get go.Fishdizzle said:would there be any benifits to getting a STI ecu compared to Cobb AP vf39 map?
No, you cannot use a MT map for you AT...but you can get a '04 COBB FXT AT AP...then get it protuned to run the VF39.Fishdizzle said:ok next question would be ... they only make a VF39 map for the 04 manual ... could i use that map on the auto or am i SOL?
AT Cobb maps are available, I believe. Try emailing Christian and seeing if he can send you one. If not he can tell you when it will be available (no snide comments here, please).Fishdizzle said:ok next question would be ... they only make a VF39 map for the 04 manual ... could i use that map on the auto or am i SOL?
