i'm running 450cc when i was running my AFCneo and everything worked out fine. It shouldnt be that hard to install the chip if you have soldering skills. let us know how it goes. make sure you take out the AFCneo or initialize the neo before you run the ecu.silviaS13lover wrote:yea, i tried that. nothings working. my friend said my injectors may be too big for the neo to handle. I just orderd a chip from jason, so it should arrive tomorrow. how hard is it to install in the ecu?
