I wanted to expose the problem: I have read with kess v2 1.89 a mercedes compressor 190 hp.; it took about 41 minutes by making use of the classic obd and reduction cable obd 38 pin mercedes. the question is this: can I write this ecu with kess v2 since reading different forums describing the procedure in writing of the food 2-pin 12v. then the kess manages to write it in serial with the reduction in obd male/female, and the final socket 38-pin seen that has read? thanks
