    Default LMM OS 12628594 boost tables

    Hi All,

    Just to let you know that I found an error in our .calz files for the desired boost table {B2206}, it's not actually modifying the correct table.
    I will fix this for the next update.
    Sorry if this has had you wondering where all that boost has gone!!

    Cheers,
    Ross

    I was wondering why I had to use the minimum vane position tables to make boost on my dad's LMM. Thanks for the info.

    Default 08 LMM reduced power

    Hello Ross.
    I have not been on the Forum in a while, have been busy with the Hydrogen fuel on Demand, that is going well, doubling fuel mileage, and reducing emmissions, Problem at hand local Gm dealer called me in , for a 08 LMM they had installed a new DIC, they also did recent Tech 2 updates,when told not to. young Tech did not know.DPF was off, It is now in reduced power mode, I reflashed it with same tune in my 08 LMM. engine starts, after 30secs, back to reduced power mode at idle. it can be driven for approx 1 mile and limp mode goes away. till the next stop,and back tp limp mode at idle. do you have any ideas. I been away from the tuning so long ,I'm a little rusty.correction alot rusty.I appreciate any Help..... Rick. EMAIL= Rick@HPRND.com

    It was requested the .tun file be removed as an attachment.

    Did you full flash the old tune back in?
    You also need to check DTC's when it goes in to reduced power to give yourself some idea on what it is complaining about.

    Default customers 08 LMM in reduced power

    Yes I did do a full flash. when I check for DTCs my EFI v2 tells me the controller is not compatible, Yet I can clear the DTC check engine light and and get it out of reduced power mode.while engine is running. and intermittently at idle it will. put itself back in Limp mode. is their any EFI updates I need to dowmload to be able to look at the DTCs when working with the LMM.. LBZ and all earlier models work ok. I can read the DTCs..with them. That tune is Nicks tune. it runs well with the hydrogen. 0 smoke... 25Mpg local. 32mpg hwy.. 450rwp on the dyno with my 08 LMM.

    Thanks for your time and Help Rick
