Well greddy reflashed my first blue box because of misfire codes and this did not work so they sent me a new one. This one does the same thing. Basically gives the car a rough idle and after a day or so throws a cel for 5 codes. (misfire on 1,2,3,4, and a random misfire. So I double checked all the wiring and my connections (soldered btw), and everything looked perfect. Then I re-connected my map sensor wire and disconnected the blue box all together and my car sounded perfect. No rough idle, misfires or anything. Has anyone else experienced these kind of problems before??? I am really getting annoyed with these misfire codes and the blue box.

 

triple chek your whire something is wrong there

 

i had a bad blue box, also. The car would boost fine and idle perfectly, but once VTEC kicked in, i'd get a Code 3 for the map sensor. It would hit full boost fine when not in vtec, but going into vtec was a no-no. I switched to the AFC hack and everything is fine. the car just runs really rich and occasionally dies when coming to a stop.

 

dirty little box

 

I must have checked the wiring a dozen times. Everything is hooked up correctly according to the wiring diagram that I received with the turbo kit. All my connections are nice and tight. I started to think that I hooked something up wrong because I have the same exact problem with both blue boxes, however I have been through the wiring many times and everything is hooked up correctly.. Any suggestions would be very helpful...
