    Default Can we get, B9021, injector minimum pulsewidth, for 1mb PCM????

    I was just wondering if any more work is being done to add this setting to other PCMs?

    awesome, so can i assume no more updates or additions will be made to the early PCMs?

    B9021 was found by various users who probed various binaries... i.e. a collective 3rd party effort.

    There probably won't be any more EFILive additions to LS1B nor any 3rd party additions.

    Finding this parameter for the 512 pcm's was relatively easy as the addresses were very similar, & getting a binary file was just as simple. 1mb files are not so easy.(for me anyway)
    The other problem is in knowing if this parameter is coded into the 1mb pcm & if it even works the same way.
    Have you come across issues running larger injectors in these pcm's that will not allow you to command a small enough pulsewidth?

    Yes, I have... 04140003 is my most recent example... I have others too (and it sucks)...

    I really really really wish that someone could do this for us! How is it that HPTuners has this available to them in the 1MB PCMs (engine/fuel/transient/min fuel milligrams) and we don't? This is my one and only gripe with EFILive! I have several cars/trucks that I can't clean up the idle the way they should be because of this. My only workaround is to get someone with HPTuners to change the table and then pull it out with EFILive to use as a base file - but this is cost prohibitive because I don't know anyone with an unlimited HPT cable...

    Hi Bret,

    The existing cax files don't cover OS files bigger than 512KB, I don't see any other cax files.

    If you could send both files in .bin format I should be able to find the modified parameter & build a cax for it.
