Jim* Posted January 28, 2013 Share Posted January 28, 2013 trying to figure out if my car has a piggy back ECU or a FCD or anything and came across these two boxes not quite sure what they are anybody got any ideas? there probably nothing but it will all help with my search! As the car is running 1.0 Bar and I can't find a FCD I'm struggling too see whats going on, the guy I bought the car from told me it had been mapped but I can see that it still has the standard ECU! heres a few pics of these 'boxes' I found just under the passenger footwell. The first unit and just above you can see the other unit with all the wires going into it. Front view of it And the above box Any help appreciated! Quote Link to post Share on other sites

Addymk2 Posted January 28, 2013 Share Posted January 28, 2013 The only way to know really would be to open it up tbh but I wouldnt recommend it. Aside from that I have no idea Quote Link to post Share on other sites
_shaun_ Posted January 28, 2013 Share Posted January 28, 2013 (edited) whats the black box behind the ecu? in the last pic Edited January 28, 2013 by _shaun_ Quote Link to post Share on other sites
Azz Posted January 28, 2013 Share Posted January 28, 2013 Sure looks like you've got something extra there ! Quote Link to post Share on other sites
Jim* Posted January 28, 2013 Author Share Posted January 28, 2013 yep just found out it's a JAM FCD! so there's that question explained! but still no sign of fueling being adjusted! so it looks like it might have been ran at 1.1 bar with no fueling mods Quote Link to post Share on other sites
akyakapotter Posted January 28, 2013 Share Posted January 28, 2013 Mine was running 1.3 on jam fcd when it came from japland no fueling mods crazy Japs Quote Link to post Share on other sites

corofin12345 Posted January 28, 2013 Share Posted January 28, 2013 (edited) i wouldnt worry about it just yet.. to ease your mind, comp test the engine to be sure.. remove the FCD and turn down the boost below .8 or buy a aftermarket FPR and get both set up on a rolling road or via wideband Edited January 28, 2013 by corofin12345 Quote Link to post Share on other sites
