I've just installed the hks pfc fcon today and all looked well till I went to start it and it wouldn't start properly. I can crank it over but it seems as if there is too much fuel when it goes to start and it just splutters and dies in the space of 2 secs. I pulled out the fcon and put the standard ecu back in and it started fine, put the fcon back in and still the same problem. I tried changing the settings on the dial inside the fcon from 5 through to 0 and got no change at all (i recieved the unit 2nd hand set at 4). My car is a S5 turbo model and is completely standard. Anybody have any ideas? Thanks

 

Your F-CON is dead.
