    E46 cluster latency??

    Hi Folks

    A while ago I have developed a circuit board that will show oil pressure and temperature on the older K-bus equipped cars such as the E34 and E32. Actually the board is capable on displaying more than just that.

    I have been approached to develop an I-Bus version of the engine oil interface. I did just that based on the TH3122 and I have it up and running hooked up to the Ibus Analyzer.

    My problem: I do not have an E46 to try this out on. On the K-bus, E32/E34, I have to repeat/update my message about every 200milliSecs or the display flickers.
    What is the latency of a message displayed in the E46 I-bus cluster?? when I send a message to the cluster display, how long does the cluster display display my message before it is automatically erased?

    Thanks in advance!!

    If you go down to the woods today, You're sure of
    There was a pluin for the RoadRunner front end that sent text via the iBus to the E46 and E39 custer displays, have a look for those threads.

    I had already done so, didn't find the answer to how long a message stays on the display before it is auto erase...

    hopefully somebody can tell me what the repeat rate has to be to have a flicker free display
