    For what ECM/PCM/ECU?

    Do you know without a shadow of a doubt that they are genuine, and not Chinese knock-offs?

    What does this topic have to do with OBD comms protocols?

    Thanks for response! The car is 2010 dodge challenger with 3.5L engine. Recently installed supercharger. We have 7psi of boost. I bought these injectors from ebay (https://www.ebay.com/itm/282587375873). About OBD sorry maybe I create this post in wrong subforum.
