    Default LML Flashing Support

    The Duramax LML comes close to the top of the list for customers asking for support as EFILive has historically been 'the' tuner to run for Duramax owners. Since hitting the Dealers' lots in 2011, we've held many discussions with many people on the pros and cons of supporting this platform whilst keeping a close eye on the struggles the European tuning market has gone through with their own versions of the EDC17.

    The issue has been, and continues to be, that EFILive traditionally requires customers to read their ECM via the OBD2 port to generate the file to be edited and then re-flashed. The OBD2 read restriction in place from the factory effectively prevents this first critical step and simply cannot be bypassed, serious LML development never commenced based on this issue alone.

    As we discussed in our January newsletter, EFILive plans on expanding our structure for adding additional controllers where customers create their own tunes with external software and simply use EFILive as a convenient way to deliver tunes to customers, much like the read/write functions that already exists in our software for the GM V6 Bosch ECM's (E55, E69 & E77) even though EFILive offers no mapping for these ECM's.

    The Duramax LML will be the next ECM to be supported in this fashion as EFILive has been busy adding LML flashing functionality. With advancements in third party tools, our historical stance has changed. Given the OBD2 read restrictions, customers will be required to physically open their LML ECM, solder a wire to the PCB and read out their stock file using external hardware/software, then create and edit their own maps using third party map editing software. EFILive will simply provide the OBD2 flashing mechanism through our V8 software and FlashScan V2 and AutoCal hardware, giving tuners a familiar and consistent way to deliver tunes to their customers. Most importantly the V8 software will also implement checksum corrections to the LML files so they can be externally edited via other software and fixed ready for programming. Enhanced scantool data is already available for the LML.

    Given the cost and complexity that needs to be invested to obtain and edit the LML file, this solution is clearly designed to provide those professional tuners who already support, or plan to support the LML via ECM exchange program rather than an individual looking to tune their own vehicle.

    Our first release will not include any mapping, and EFILive will not offer any map finding services or hints on how to locate maps in bin files, however we plan on offering basic mapping support for the LML in the future.

    EFILive does not plan on offering any hardware solutions for reading the files out of the LML nor are we able to provide stock tunes for customers, we have however created a file import function for one of the European JTAG read/write hardware solutions.

    Early indication suggest that a full setup for read hardware, software, along with mapping programs will cost in the vicinity of $10,000 USD. This is NOT a cheap proposition and is definitely targeted at high volume workshops, not individual tuners.

    There are already several vehicles running custom tunes programmed with EFILive LML Flashing support. Further beta testing will commence shortly across a wider range of vehicles and public release will follow in the very near future.

    Regards,
    The EFILive Development Team.

    I believe that's more of a rough estimate, everyone needs to understand that this release is ONLY flashing (I believe scanning/logging is already supported). In order to obtain a tune and build a tune, a 3rd party application and hardware must be used. If you have to develop everything yourself, this will be a lengthy and expensive process. This is where the 10k figure comes in as I imagine there are a few workshops that have already invested the R&D into it but would rather use EFILive to flash their updated tunes than develop yet another solution for flashing.

    Regardless, this is good news for the LML guys!

    It's not a solution designed for an individual user, it's simply not cost effective. It's designed for those workshops who have already invested heavily in alternative tuning tools as a delivery mechanism to their customers.

    I should also say, that we can't control the outcome of the solution, we can only work within the constraints of the ECM. The only reason this is being offered is because we had a number of workshops say that flashing support would assist their end user delivery. If it wasn't for their ingenuity and persistence there wouldn't be a solution at all.

    The measureable cost extends well beyond the figures in the first post. The workshops involved have invested 100's if not 1,000's of development hours in creating and finding their own maps for editing.

    Cheers
    Cindy

    so would is it possible that we could buy a tune from said workshop and use our V2 to flash a tune into our LML?

    I want to make it clear to everyone, it is still not possible to read the LML ECM without pulling the cover off and soldering wires, that is how it is on all EDC17's, it's the nature of the beast, but unfortunately it really restricts just how DIY tuning an LML can really be. Hence we've tried to point out that this isn't a full EFILive for LML tuning solution, but it fits well for others that have been able to get to the point where they have tunes that need to be flashed without pulling the ECM apart.

    If (and only if) they are able to obtain stock tunes and modify the tunes, none of that is possible with EFILive at the moment, but if you are able to get a tuned file (an EFILive .ctz file) for your truck then yes, EFILive can flash it in. Reality is this is happening all the time with Autocals, the end user just flashes in tunes the tuner creates for them, it makes no difference to them how the tune was created, same for the LML.
    I imagine it will be pretty easy to figure out from online posts who is able to offer this service. It's not EFILive's business to say how they are obtaining or creating the tunes, or even who it is, much like we wouldn't openly advertise tuners anyway.
