ok after tune and dyno, car runs perfect and very nice. burn the chip as bin.file. plug it in. runs very nice. but after i took out the blue box and cover the ecu. then test drive it again, fuel cut at 4k rpm. Then i plugged blue box back in, it drives normal again. my question is: i want to take blue box out and leave the chip there without blue box. how i do i fix it without plug the blue box. or should i buy the s100 and burn the s200 tune map to s100?
p.s. s300 is not option for my cutomer
