Ive just finished installing one of these things and my check engine light is now on and car is running like crap. I wont rev over 3000 rpm and it spits when it almost get to that..Also im not sure if im useing a hot wire or a flap type ecu setup that could be a big part of the problem. I did the initial setup and all went well until i cranked it to set the settings and all these problems started.. Ive run out of ideas/knowledge if anyone has any ideas or needs more info let me know..

Thanks
