I've got the lead now & downloaded the drivers as directed in the set up guide but when I connect the lead to the PC it reads "incorrect key or missing file cannot connect to vehicle" I am assuming hear that this is because it is not plugged into the ECU any ideas. Also out of interest only can anyone tell me what the parameters F1-3, L1-3 & I1-4 are, I see they are different settings in the map but I don't understand what they are. Thanks in advance guys
