O.k. I finally got my street ported engine in, it also has upgraded injectors. I did install a Power FC. I seemed to have done everything right, but when I start the car up, it pours out smoke, fuel burning smoke and doesn't want to stay running. Seems to be running really rich. Now I also read in this forum that on the older Power FC's four wires had to be cut, would this make it run shitty if those wires weren't cut? or is this caused by something I may have programmed wrong in FC?

As with any new engine install and new ecu the set up needs to be tuned. Especially now that you have changed the injectors. I would expect it to run like ass until you get the maps straight.

Kind of to answer my own problem, I forgot to turn back the injector duty, so the 850's were running wide open.

Even when you get it running, please take some advice and tune it! A rotary should never run too rich or lean for that long, if you want longetivity anyways...
