    Default DSP5 valet mode

    ok, I have the switch wired up on pins #1 and #37 in the black connector. I have all 5 limp home tables set to 0mm3 from 1k rpm and up. I also have B0740 min. inj. qty set to 0mm3 from 1k rpm and up. Neither position of the switch will limit fuel.............what gives??

    I do NOT want it as a dsp table I want to use a different switch that I can hide. I do not want this for "valet" I want it for added anti-theft.

    The first time I tried it, I did not have the switch grounded in #37, I only had it to body ground and B0733 was the only one that would limit fuel and only if B0740 was lowered as well, BUT the switch did nothing, it was stuck in that limiting fuel mode. Now??? I don't get it. Am I missing something?

    Being its already here, and it didn't have an answer, I figured I would revive an old thread to say that Im having the same issue with the Valet mode. High Idle works flawlessly, DSP works Flawlessly but when the Valet Mode is enabled in the tune{A0140}, it instantly reverts to Engine Protection Mode 1 {B0733} regardless. If you disable {A0140} (only change made to the tune) the truck runs fine, no engine protection mode. Here are the Segments and OS im using currently

    5875805 Operating System
    15904640 Engine Operation
    25779295 Engine
    15879109 Engine Diagnostics
    15879098 Fuel System
    15228743 System
    15233750 Speedometer

    Any input Ross?

    I don't expect a fix, just looking for input if this is a known issue or not and if not, just bringing it to your attention. Are there any work arounds?

    I am able to replicate the issue on this truck using 2 different ECMs.

    I'm gonna try a few other OS's to see if i can replicate the issue on those as well as different Segment combos.

    And i did verify that the pins are properly seated in the connector and making good contact.

    To add I have also rebuilt the DSP tune several times to ensure that it wasnt just a build error when it converted the base tune to a DSP5

    Neither the DSP-5 valet mode or DSP launch control on the 04-05 LLY actually works.

    Kinda frustrating, but I guess not enough people tested it back when LLY was fresh on the R&D table to point out to Ross that it is in fact broken on the LLY's.

    It works perfectly on LB7, but I was never able to get it to work on LLY, so I gave up on it years ago.

    I knew the launch control never worked. But never tried the Valet till today. Well... That sucks I guess. Hopefully the E60 doesn't get retired before its fixed

    All news to me guys, but sadly it is unlikely it'll be fixed, too many miles travelled to turn back.
    I no longer monitor the forum, please either post your question or create a support ticket.

    For the handful of people that have used the feature in the 9 years and 4 months since the documentation was first available in January 2007 the best all round solution may be to remove DSP2 from future software releases for LLY.

    Cheers

    Wait.... why remove DSP2? The only problem was with the Valet mode and DSP Staging thats included in the DSP5 COS
