Hello guys i just installed my hondata s300 v3 on my p28
When I plug my ecu to my laptop (note that i dont have it plugged into the car its just plugged into the laptop) i get a stable green LED light at the top right and right when i plug it in it lights up green at the bottom then after a second or two it changed to the other LED and it blinks red rapidly.. what does that mean? Or is it normal? Also i am not able to upload a map even when i plug the ecu to the car.
