Is it still possible to use this app to simply change the VIN?
I had my truck worked on and he changed my VIN to something he already had Licensed and now my License doesn't work anymore...
Thanks,

A couple things I ran in to that you might like to know.
The 5.3.1.1 App that I used, asked me to confirm whether I had a 1mb PCM or a 512. I wasn't sure, but figured that the 0411 was a 512? It apparently worked, but, of course, I was unsure if maybe I could have done some significant damage. Maybe this Thread details that, but it's now a bunch of pages. Any way for the App to 'divine' the info?
Also, the 'field' that displays the VIN, doesn't appear to be 17 digits wide so I was unable to view it in its entirety, Not a big deal, really except there didn't seem to be anyway to 'scroll' it.
It may be a nice 'upgrade' if the App offered to save/store the 'current' VIN. There didn't seem to be anyway to 'highlight' the existing VIN in order to copy/paste it in to a text file. And, after the "Change" button is pressed, the resulting field is blank waiting for input.
Since I think I've already purchased 4 Licenses for this ECM, I really appreciate being able to return it to its correct VIN.
Thanks!

I've been meaning to do this for the last week but with the weather and a NASTY cold I haven't found the time or ambulation to speed this much time on my computer.......
What I'm about to show you is the end all of PCM recovery. The ONLY way possible to recover a pcm beyond this point is with a BDM.
Ls Droid > Hp Tuners
Ls Droid > EFI Live
Ls Droid > WinFlash
Ls Droid > LS1 Flash
Ls Droid > Ls1 Flash Tool
Ls Droid >SPS
Ls Droid > Pcm Hammer
No other company, person or tool has ever done or made possible what you are about to see.....Now the method I use to force the PCM into a recovery mode works with every tool listed above but your results will vary based on what recovery mode it boots into. HPT, EFI Live and Winflash have no trouble dealing with mode A2 01, EFI Live and WinFlash are also able to deal with mode A2 02. With that said I have yet to find another tool capable of recovering from an unresponsive PCM that is forcefully booted into mode A2 00, that's not to say one doesn't exist but I have yet to find a tool that can deal with this mode.

I have been tracking the progress on this project for a while and want to say thank you to you and your team for spending so much time on this.
I have little experience with tuning other then playing with obd1 honda stuff. but will this end up being a easy solution for average Joe to delete vats and emissions junk doing motor swaps? Or do we have to start learning how to read and write hex code to make these programs work for us?
once again thank you for your time. Keep up the solid work.

A full fledged tuning suit on a phone is possible but it's well outside of my ability to create any thing that was comparable to EFI Live, Hp Tuners or any other full blown tuning program. Now that's not to say it can't be done......tuner pro RT has already been ported into Android for OBD I stuff, while XDF's are limited it does open up a possibility though that if my app can do full read/write that the ported version of Tuner Pro could be used to modify the bin and then reflashed with my app.
There is a bluetooth device on the market that cost less then $100 and is capable of 4x high-speed read/write from a hardware perspective and the company has said they are willing to create the firmware for their device to add 4x mode and increase the buffer size to allow 4K read/write blocks( The same size blocks used by the big two tuners) if a commercial program needed such support from the device. I under stand why they haven't added the 4x high-speed yet.....why spend the time developing it if it's not going to sell more of their product.
While Highspeed mode and 4kb blocks would be nice it's not necessary for a full flash it just takes four time longer. For example 1x calibration only write using 2KB blocks in low speed mode takes just over 4 minutes on a 512K pcm and around 7 1/2 minutes for the 1mb pcm. While that's much longer then current commercial products take it's still faster then nothing.

While I agree creating a full-blown tuning package similar to Tuner Pro might be a bit out there, how about something similar to what a Handheld device such as a Livewire TS that can make small adjustments to Idle, gear ratio, tire size etc, as well as select from 2 - 3 preset tunes?

Now pre-made "tunes" are a much different story but then your opening up yourself to heat from the EPA.

New guy here. Been working professional as a master mechanic for 25ys, and have had to go through the pain using of JAVA apps from the manufacturers to flash pcms. I hate java. I remember when folks used to compile their software before you used it. Now, everything is shipped before it is ready to run. Drives me in circles.
All I can say is holy crap, this is an awesome build of software! Stayed up till 4am reading all of this thread. Got a little OSD seeing the full potential of the project. Kur40 must be glad he chimed in, too.
I tried installing the read only version on my Samsung SM-J320A, and had ordered the OBDLink MX+ unit. But I keep running into "there was a problem parsing the package" error. Is my phone too feeble to use the software, or am I missing something? The 3rd party install box is checked.

The current read version of the app does not have a min Android version in the app but it likely should, Any version under 5.4 is going to struggle running running the Read App and simply can't run the write app. So I've applied a version check that sets the App to require Android 6.0 and up in the write side of the app I've been sending out to those testing it for me. I've bent over backwards working with people trying to get it to work correctly in older versions and was close to a solution but due to changes in Androids min API level for app to run on newer phones I couldn't support both.
I have not personally tested any version of the App with the Obdlink Mx+ so I can not promise it is going to be compatible but based on my research it should be fine.
Feel free to PM me with a screen shot of the error your running into if its more then an installation error.

The Obdlink Mx+ unit has not arrived yet, but I will let you know. I have my eye on a few Craigslist PCMs, also. I won't be doing any PCM writing at work yet, as the customer with the '39 Ford Business Coupe with a 6.0L is a bit sporadic about when he drops by. I at least will build a test bench for the 0411 pcms. Then I get to find a proper xdf and start my learning curve about custom LS tunes. I expect to see a larger set of tables compared to my 95 LT-1 wagon. The same guy has 4 other LS-equipped classics, also. He will let me tinker around a bit with the tunes, since the people who built the vehicles mostly only knew bodywork. I suspect it will be late spring before he starts showing up to fix random leaks. (neat freak)

Once you get the Mx+ do let me know either way what the outcome is since I've been wondering about it for a while now.
