Hi guys,
Over the last 6 months or so I have been putting an 05 Busa motor in a Smart Car, I got it running today! I had some problems and questions and was hoping I could find a little help here.
Question #1 When we first got it running one, maybe two of the injectors wasn't getting a pulse, My friend was over who is an expert foreign car mechanic, he said it was probably a bad computer that would make only one or two of the injectors not fire, I had another Busa motor laying around, this one an 07, I put that computer in the car and it cleaned the problem right up...My question is: Is this common? Is that other computer junk? if so, that really sucks!
Question #2 It seems to backfire on deceleration and shoot flames, Is this to be expected? It has a 4-2-1 header and a Magnaflow muffler.
Question #3 Do you guys think I need to get this thing tuned to really run right?
Question #4 Any thoughts on my intake design? Some one told me it needed to taper down towards the last cylinder, is this true?
there is a thread on the car here:

Thank you for any help!
