    Dennis, E68 doesn't exist. Maybe an E40?
    When you say he can't get in, do you mean he can't read the tune out or can't communicate with the ECM at all?

    Hi GMPX, thanks for your reply. The ECU is a E67 not E68. This is a GM performance ECU.
    He can open the engine calibration,engine diagnostic etc. but not the systems file where the security, fan etc. controls are.

    ok, that makes a little more sense.
    The GMPP ECM is a unique application, there is no security for starters, I'm not even sure how the fans are done on them, is it controlled by the ECM?

    The fans are controled by the ECU and come on to late. He is probably going to have to opperate them externaly to get them to come on sooner ?

    It might be like the normal production E67's where we rescaled the fan operating temp table so you could lower the turn on temp below 89degC. Before he adds an external controller let me check it out. So you know if the fans are just simple relays (low & high speed), or PWM variable speed fans?

    There is only one fan connected (no space for 2) and connected via a relay only on and off not 2 speed.

    Thanks for your help

    Is the OS in the ECM 19211212?
    Looks like they are set to turn on around 99 degC, does that sound about right?

    Dennis, here's something for you guys to try.
    Attached to this post is a revised .calz file, this defines what maps you can see in the tune, I've added the fan table in there for E67 OS 19211212 (which I assume is what the GMPP ECM is using), please let me know if it's something else.
    Anyway, download the zip and extract the 19211212.calz file in to the folder:

    Program Files\EFILive\V7.5\Calibrations\E67

    Once done, re-open the tune (no need to re-read the ECM, just load the file off the PC) and you should see the Fan table in the system segment.

    Cheers,
    Ross
