hi
I have the orig fgtech, it did do the checksum automatic , but i think it is not done correctly as car will start a few times and will not start after left alone for 10 in

Hi sr, but why do you think that this problem is from checksum?. bad checksum teorically will not allow car to start never.. computer will not start running program.. have you checked to pass all permanent feeds to contact? and also, when you have the problem.. if you disconect computer and reconect, car start well no?
