I bought a 91 Savanna recently (Im in the states), and ended up with an absolute time capsule. The car was built by a performance shop back in the day called "Street Special" (if you know anything about that I'd love to know). I'll add pictures later but its got an ancient HKS kit, RE v mount setup, etc. I Found a power fc when I pulled the carpet up and was pumped cause ive ran them in my fds, but apparently this isnt the fd pfc i thought it was. This is an FC3S AP ecu, and I know little about it. What freaked me out is the Injector menu was completely blank. Obviously this car has been tuned before (otherwise I doubt it would run the way it does with a healthy port job). Is there anyone that has experience with these thats still active on the forums?

 

Just to clarify the injector menu on the commander was blank, I accidently smashed my datalogit so I have yet to verify on a laptop.

 

i think that ecu can be tuned like any other PFC. the big difference is the software, it has some different settings for things like not having a fuel temp sensor and such

 

Also its set-up for the FC to run the stock fan clutch and not an electric fan.
