I was a little unsure of using this process but I though the savings would be more than worth it if everything worked as advertised on the website. My regular mechanic was going to be at least 1k and I would have had to tow the car to them. Not only did the process work as stated on the website but I got my ECU back quicker than expected. I was able to reinstall the unit within minutes and it worked flawlessly once I reinstalled the unit. I will definitely use ECU pro in the future if I have this issue again and would recommend to anyone else to do the same.
