    Sorry,

    I’ve read it like ten times.

    We are desperate. These trucks need tuning bad.

    Can you give us any hope?

    Well then you understand what the problem is, asking over and over for a fix isn't going to change the design of the ECM.

    You can go buy a H&S programmer if you want.

    This is my first time asking. I'm just taking my turn.

    Defiantly don't want to buy an H&S at all; it pains me. I may have to for the short term though.

    I will take your suggestion and write the letter.

    I'll keep the faith in you guys. I know you will figure something out. If I can help in any way, let me know.

    Best Regards

    I know, it's not the first time we've been asked or offered suggestions on how we can offer support, it gets tiresome when the answer can't be changed.

    Mmm, consider it a long term purchase.

    No we won't, it's a done deal, the LML ECM is the way it is, GM won't change the design. Everyone just needs to accept this fact and move on or buy another truck.
    I try to relate this situation to people by comparing it to the PS3. 'Mod chips' came out for the PS1 & PS2 not long after they were released, but still nothing for the PS3 five years after it's been released because from the first day SONY started the design they wanted to stop exploits and they've succeeded. The Bosch EDC17 ECM design spec I have no doubt comes from the manufacturers wanting to stop tuners modifying them and it's working. We all just need to be thankful that the rest of GM's fleet hasn't headed down this path.

    What about scan tool PID support for BBL and system diagnostic for trouble shooting problems using the Scan Tool?
    Many of the PID don't have the correct definition's to work with the ECM when BBL.

    So a friend of mine has an old 88 BMW E30 that he turboed and I have been helping him with tuning using tunerproRT and moates ostrich. First of all THANK YOU EFILIVE!! After using that program i want to come home and hug my V2 and tell it that i'll never let it go! We have it SO GOOD that we forget that we are practically the only ones out there that have a tuning platform that normal people can pick up and be able to learn how to use it. TunerproRT is by no means junk either, I consider that to be middle of the road tuning software, some people are seriously still having to manipulate hex code! Anyways, so i asked my friend if he knew anything about how any of the tables work together with eachother since there's no documentation and he said that he didn't know and mentioned that there are people out there that know how to write from scratch a .bin for that car since its so simple...

    So unless you are able to write a .bin of your own or get a standalone i don't think custom tuning is going to happen. H&S looks like what your going to be forced with.

    which brings me to another thought I've had. Why are people buying LMLs? The only benefit i can see is the better frame. I'm keeping an eye out there for a wrecked 3/4 ton swap in an LBZ and problems are finished Also if people boycotted them maybe GM would notice... but probably not.
