    7427 OD Change Knock Sensor Quantity

    We are swapping TBI on to a Toyota 2F inline 6 and will be using a 7427 ecm and 4.3 bin. On the 2F there is only room for one knock sensor. I know changing the quantity can be done but I really need to learn hex. I found this post showing part of it.

    What to do with that is where I get lost.

    I will be using the BDYT bin attached or maybe a manual one, BJFD , if I can.

    Any help in teaching a illiterate hex person would be appreciated.

    Well I'll start by sharing what others have taught me. First understand how to count in hexadecimal:
    http://www.tunerpro.net/tutorials/UnderstandingHex.htm

    TunerPro open with your bin and XDF loaded. Tools, Advanced, Hex Editor.

    Then look up L4E6A as in picture. But looks like the only change you need is L4E6B so go there and make the change. Save bin.
