Hi All, now that we have a menu to import Jtag files, where can we get info about those files ?. I would ike to know what software are "approved" or ok to generates fls,mpc,epr files to be used by Efilive. Also can raw bin files from tis2web could be used ?
Thanks
I know this sounds bad and really confusing considering it is our software, but we have been asked not to tell anyone what JTAG hardware to use. :angel_innocent:Quote:

instigators.. lmao
Yeah yeah I get it. I think I'm sitting on a sweet piece of equipment on the shelf with no time to learn the in's and out's of it.
From what I remember when this was all unfolding (and we don't own one of these Euro tuning things), the cost is around $7K for it.
Yeah I'm a little over 6k got the once piece. But I'll be into it 7 by the time I get a few more piecesQuote:

You would be correct.Quote:

It doesn't give you anything more than really expensive hardware that is a total pain to use, it is not a magic bullet by any means. I had no idea about the on-going subscription fees.
it will always work if you don't pay the subscription but you just won't get new ECM's or protocols as they come out.
So what about for Cummins? We don't have full parameters for cummins. Yet those are still getting deleted as tunes downloaded currently.Quote:

Want to screen a screen shot? And I guess I missed why you don't offer it?Quote:

Re what AT will work on, TBH I don't really know (or care), we don't own one, I'm just passing on what I hear.
For anyone considering the investment in extracting raw bins from ecms with an AT, this is what you are required to have.
The third party software/hardware, invest $6k-$7k
A bench harness/ecm for LML, avg investment $800-$1000
Yearly Subscription to TIS ( GM ONLY ) which the service programming is $1000-$1400/year last time I checked
A way to bench program and then boot read the ecm, TECH2 $2500 or Mongoose Cable $600 or an MDI $2000 for programming alone.
So if you think investing $10k to get stock ( BIN) files makes financial sense, when Kory and I and a few others have made it quite reasonable to buy them in EFI-Live Format then I think that $10K must be burning a hole in peoples pockets.
A raw bin file is like looking at CHINESE, there are no labels, there are no markers, there is nothing that will help you to do what your trying to do and without a way to decipher that code its like looking to assemble a 10,000 piece puzzle with no picture on the box.
There is a reason that very few people are doing these, we are not hobbyist tuners, its not a dig at anyone who is a hobby tuner, but the reality is that unless you want to spend a lot of time and a lot of money to do this, you are just not going to be able to easily do any of this, and your sales volume will have to be such to support the effort to even get it started.
Good Luck
For a spare LML ECM??? I have like $14 in my bench harness, and LML ECM's can be had from the junkyard for $250.Quote:

But if you have some special bits, it makes it a lot easier. :)Quote:

Yes you sure can get a 2/day for $50, but I process sometimes 15-20 TIS tunes a day, so for me its not worth going there for $50 a clip, I supply 2001-2015 Tunes to a lot of shops and other tuners.
I have all the above mentioned hardware in my post, I might not need it all to be legitimate and I am sure the "clones" work just fine, but to each their own.
I tried a Chinese CANDI Module and it was junk and worked 1 out of every 10 times I needed to use it, so I bought the real one and its been flawless, just like my TECH2 is genuine and not a CHINA CLONE.
If I have a need for a new bench harness, and if your willing to build me one for $25 or $14, I sure will send the business your way, as that would be a nice savings over the $125 or so I paid for the LML one I have without the power supply and the extra things I added to it so that I can do what I want with it.
Thanks for letting the others know there are alternatives available, as information is good to have.
Catman, tell ya what to use that JTAG tool for... Reverse engineering the OS of all these other BOSCH ECM's out there that EFIlive could easily be used for. Like the VW and MB common rail platforms. Basically "Identical" to the Dmax and C in all hardware aspects, besides the OS. I'll happily send ya couple for starters to play with.
You guys do know it's legit now to write your own ECU OS? No different than rooting or jail breaking a cell phone. Maybe this will help open up more of that information..

This is partly true, operational concept is the same but there is a few key differences in CAN comms for reading/flashing that make it difficult for us to support every EDC16/17 ECM out there.Quote:

The other one that needs some serious love is the MEFI5a used on GM Performance setups like the COPO Camaro. That same E67 unit powers the largest percentage of performance watercraft in the world. It's CANbus protocol is SAE J1939, which makes it very popular for engine swaps to. I know it's been brought up on here before, but feel someone is missing the boat, load of sales.
Legitimately...Quote:

Yeah we have one here and you are right there is a big market, but there is only so many hours in the day.Quote:

I just haven't taken time to captured that raw packets to replicate it. But this does give some incite to how easily tunes "can" be changed with only simple wheel button combinations, rather than hardwire...Quote:

Not all Bosch ECM's have RSA sig active, not all ECM's have RSA active on OBD-II flashing. You can't trick it, most of the bypassed ECM's need to be JTAG'd first and killed off that way, something not really in line with us. But this is the primary reason that EFILive has not contemplated DSP for the LML (regular tuning of course is no problem). As you know we've done DSP (or CSP) for every other Diesel ECM we support tuning for, we know how to write the code but sometimes the game can't be played.Quote:

Need a kickstarter campaign to get development rolling? I've had more people ask about MEFI5 lately than all others. The current software leaves much to be desired. I've even considered swapping them out with a standard E67, but that requires pinout changes. So please reconsider it's market value. A DSP2 option in MEFI5 tuning would be a hot item since the performance marine guys are into variable boost and timing based on fuel options. Selectable tuning is fueling the aftermarket ECM market in this area.Quote:
