Houston, we have reflash... PCM reflash tool
I finally got around to writing a tool that can reflash later intel based PCMs. Works with the AVT-852 OBD-II cable (expensive, but very nice easy to use cables). Caveat is that this one is for the '279 and similar black-box PCMs (99/00). Another user is writing one for the '411 PCMs, but isn't done yet. I don't want to step all over his toes, so I will keep the source to the reflash code under wraps for now, but the app I will post after a few more tweaks. Since its not for the '411 its probably only useful to me and maybe someone with an Oldsmobile Bravada 
Good news anyway is that its doable and most of the info is applicable to other pre '04 MY computers.
There is a freeware tool that reads the LS1 PCMs, but back when I was helping with the reflash version, we were having issues with the hardware and flash. The code logic for the black box would also work on the '411, provided the hardware interface is changed. The output for the +12V program voltage is set up a bit differently in those than the '279 which simply uses one of the MCU I/O ports to control the Vprogram on the main regulator IC.
Real bitch to write this. The flash chip interface was the easy bit. The hard part was getting the re-appropriated 68HC11 they used for the datalink controller to work well. PCM runs at 16 MHz, but it runs at 2 MHz, and there are some hardware bugs in it that make it misbehave in strange ways.
The app does both calibration reflashes, and full reflash of the OS. The calibration reflash is pretty safe. I was able to pull the plug in the middle of a reflash and still recover the PCM and finish reflashing it. The OS reflash also works reasonably safely now, but as I found out initially, if you booger up the OS, the PCM bricks. Only way to get the PCM back is to open it up and manually ground an address line to put the PCM into recovery mode. Also the internal controller in the flash chip locks up when the very last address on the chip is programmed. PCM still reflashes ok, but it has to be manually reset. Doubt many people will ever need to reflash an OS, tho
But since Im using a custom OS on my PCM, I had to do the whole thing.
Surprisingly, the reflash really hauls a$$. Doing the calibration at 4X mode takes about 45 seconds (see screenshots for it in action). Helluva lot better than the 5-6 minutes it took me to reflash using my pocket programmer.
Nice to have a fully flashable intact PCM, but now I have the dreaded P1336 error code, and I never did finish figuring out what the OBD message message frame to start the CASE is
Guess that will be the next project.

Re: Houston, we have reflash... PCM reflash tool
Way to go! 
How do we get this program?
I have a Black Box PCM and bench flash setup here along with the AVT-852 cable. When you had the TunerPro RT ADX for the Black Box Vortec I had tested it on my truck and worked fine!

Re: Houston, we have reflash... PCM reflash tool
Ill probably just post it here. Small little program (~150 kb). Just need to package it all together and clean it up a bit.

Re: Houston, we have reflash... PCM reflash tool
Ok, here it is. Let me know if you have any questions. Most of it should be self-explanitory. If your just using it to do cals, it will automatically open an open file window and request the bin. Click File>Upload Bin. Then it goes and uploads it. To DL the bin from the flash, click File>Download Bin, and it will DL it and save to your desired location.
Also, you have to disconnect before closing the window. The PCM wont shut off unless its reset by the disconnect command. If for some reason it crashes before disconnecting, restart the app and move your cursor to the lower left corner of the window and click. This will bring up the advanced mode. Click Resume Flash Mode, and it will reconnect to the PCM so you can shut it down.
PS: If your PCM is socketed, this code ONLY works with the intel chips. Dont try it with the AMD 29F400.
Edit: Version 1.1.0.0 is now uploaded.

Re: Houston, we have reflash... PCM reflash tool
I'll be bench testing tomorrow!
Then I have a 99 truck I can borrow to do some in-truck flash tests.
My truck has been converted to the 0411, but with this I may convert it back and work on an XDF. You had a disassembly that looked like a good start, was there any stock XDF started?
I've run into a couple PCM that needed a full OS flash, is this something possible in future? Or on bench? Wondering if the other modules on vehicle can mess up a Full OS flash?
Jayme from Delcohacking.com now PCMhacking.com has an awesome OBDII ADX started but it was for the LSIb 0411 that works with the AVT-853 cable:
http://pcmhacking.net/forums/viewtopic.php?f=10&t=2314
I've been using them along with your LS1B XDF through the RoaRunner and TunerPro RT with great results, also been working on the newer LS1b 1221156 OS that will handle the stock Vortec motor bin to use with the 0411 PCM., we'll see how much of it works and I think I have your starter Vortec ADX that could be the grounds of new Vortec Datalogging.
Exciting stuff dimented24x7!

Re: Houston, we have reflash... PCM reflash tool
I actually did write XDFs a couple years ago. I have XDFs for the 411 posted on this board. They should still be here. They cover the engine and system, but no e-trans, yet. I assume those are the ones you have, and they are for the stock '01 PCMs. I haven't done anything yet for the newer unified '02 OS.
Also NOTE that the app doesn't work on XP (at least I dont think it does) as it uses the WPF platform so it would work on windows 7 + 8. As for doing a full flash with it, I fixed the bug so it works properly now and doesn't hang up like before. Click the advanced button (hidden in lower left corner of window) and click Flash OS checkbox. Then click file>open bin to reflash. It will then flash the OS portion of the PCM. If you want to do the whole thing, do the standard cal flash first, then go into advanced and reflash again with OS checked. It will then be fully flashed. For safety only the cal or OS can be programmed, but not both at the same time.
Anyhow let me know how it goes

Re: Houston, we have reflash... PCM reflash tool
Ah, IC. I dont think I did, but I can take my current ones and just take out the custom add-ons. It will essentially be about 95% of the stock engine params + system. Since I have a stick, there isn't many e-trans params, unfortuneatly.

Re: Houston, we have reflash... PCM reflash tool
The older black box is a different beast all to itself since its a first gen OBD-II PCM. The hardware and boards are a bit different and the OS probably is, too. Not a bad idea to convert over to a 98/99 box. They are better in all respects. eficonnection.com has the connectors and the pinouts to each are aviable so you can repin for the newer PCM.

Re: Houston, we have reflash... PCM reflash tool
Also uploaded a newer version of the program with a few more tweaks. It also automatically resets the reflash options after the OS flash so the "Flash OS" doesn't need to be manually cleared each time after the OS is flashed.
I also tested it on a windows 8 machine. Looks a little funky due to the different windows styles, but seems to work fine otherwise. If your adventureous, it probably would also work on a windows tablet Just make sure to use the correct FTDI drivers for the windows version you have.

Re: Houston, we have reflash... PCM reflash tool
Hmmm repin to 98+ and use this, or wait untill a free/common man priced 0411 flash tool becomes available and swap to a 0411.. Decisions decisions

Re: Houston, we have reflash... PCM reflash tool
Either one will require repinning, but they each would be a nice improvement over what you have now.

Re: Houston, we have reflash... PCM reflash tool
First test on bench is a fail?
Select the Comm port and try Click File>Upload Bin or Click File>Download Bin.
Message: "System Message: Download Error - PCM not ready/not in flash mode"
To make sure my PCM and bench did not have issues I used Winflash to download and upload without issues.
This test was using Version 1.0.0.1 on a Windows 7 machine.
Also tried the Data Link option although your instructions did not mention it's need or use. Connect ran a long time and ended up with a Non Responsive program?

Re: Houston, we have reflash... PCM reflash tool
Did you click start flash mode? Thats what that message means, is that the PCM is still in standard operating mode. You can tell when its still in operating mode by the console window echoing all the rec'd frames on the OBD bus. In flash mode, the frames are filtered for the PCM alone, and not echo'd to the console. The echo is needed for recovery. When teh PCM requests a reflash, you click the button to start flash mode and it recovers. But it has to be during the PCMs request, or it wont ack.
The PCM does not actually have its own flash routines. GM does this to prevent people from subverting the security and being able to reflash. These must be supplied by you, the person reflashing the PCM. Clicking the "Start flash mode" button actually restarts the PCM, and uploads basically an entire operating system into the RAM (code I wrote and embedded in the .EXE). The app actually looks for the PCM to respond with a special frame indicating its in flash mode. If it doesnt see it, you get the above error code.
Ehhh, maybe not so self explanatory after all

Re: Houston, we have reflash... PCM reflash tool
How long did you wait to try agian? That indicates that the PCM is rejecting the security request due to insufficient time delay. If you key on first, and let it sit for 30 secs to a minute, it should then let you in. I get that same message when I turn on my PCM and try to connect right away. Usually I just wait, and then try to get in agian.
Oddly, though, it did grant you access: "6C F0 10 67 02 34" is valid key, security access accepted. Its possible that you double clicked the connect button and it sent mutliple attempts. How many times did it repeat like that. Did you key off and try agian? I either get in, or I get teh security delay error message if I try too early. Its almost like the PCM is denying access due to the time delay, then sending the frame denying access based on # of attempts or time delay. Let me see if I can replicate it on my bench. Ive never seen it actually grant and deny access at the same time. Only thing I can think is that maybe the frame is being sent too fast for the PCM to process. If the app "double-dips" the security frame, it could be causing that behavior. This can also happen with the AVT if it looses arbitration. It will send the frame again. This is a distinct possibility as there are frames from the driver info center there as well as possibly your radio which can interrupt the access. HP Tuners has this issue as well. I may be able to help cure it a little by tweaking the settings a bit on the AVT.
How much OBD data comes thru the console? Does it just pour in?

How much OBD data comes thru the console? Does it just pour in?

Re: Houston, we have reflash... PCM reflash tool
Ok, so it looks like the DIC is sending quite a bit of data. The PCMs response to the DIC comes every second or two, which is the two doubled-up frames. I can tweak the AVT settings to limit the response on the event its interrupted. I suspect what is happening is that the frame is sent twice and the PCM accepts the first time then sends the time delay error frame on the next go around, causing the error message. There are some software things I can do as well to improve its response if it doesn't work the first time.

Re: Houston, we have reflash... PCM reflash tool
Great work! I was wondering can you add a way to check if security access allowed, then if it returns something other than $34 unlock it. The reason I ask is because the seed/key algo is different on Duramax PCMs, I could just unlock the PCM and the rest should work. If that works I also have plenty of dumps and correct seed/key combinations if that would help. I'm willing to help just let me know. I also started a XDF for Duramax LB7 OS:15189044. Got all the checksums figured out, vats, speedo, and a few important tables.
Got my hands on a Bluetooth AVT-855 too, connects great to Android. Works with a few terminals I tried, my goal is to read/write the PCM from Android. I'm all over the place right now, last night was fun with Diagnostic Data Packets, who knows what will happen tonight.

Re: Houston, we have reflash... PCM reflash tool
The PCMs thru the years are different internally. The organization of the calibration and OS varies on the flash chip. Also, the routing of the +12V supply to the flash protect varies as well. Both the black box and LS1 use different hardware addresses for the +12V supply as well as different memory maps. It may work if tailored to the duramax PCM, but a hack would be needed for the PCM in question before writing the reflash code. What year is the PCM? Have you opened one to see whats inside? Main things to look for are the flash, datalink controller, and CPU/MCU used. If its close enough, the '411 hack can be used to work out the details and hook up to it.
The LS1 Flash Free reader on PCMHacking.net has a key finder built in if I recall. You could try it and see if it finds the key. If it manages to get it right away than the security algo is the same.
If there isn't one already, starting a thread on PCM Hacking would be a good place to start. Posting pics and so fourth will help get some more details on the guts of the PCM fleshed out.

Anyway, I changed it so if it does get both at the same time, it will enter flash mode, anyway. Try it and see if it helps.

Re: Houston, we have reflash... PCM reflash tool
Eagle, are you trying this on the bench, or in a truck? If its on a bench, then Im really perplexed as to why it acts the way it does on yours. Also, its not a black box with the round 5th connector, is it? The later ones all have 4 connectors with a plug in place of the 5th. Earlier ones are basically a completely different computer.

Re: Houston, we have reflash... PCM reflash tool
Yes it's on a bench and a 99 Vortec PCM. Plugged fifth connector.
As a test, it does flash and read with TunerCat WinFlash OBDII.
Will try the new program and IIRC have another PCM here too!

Re: Houston, we have reflash... PCM reflash tool
The fact that it still boots means that the flash was probably good. I suspect the 99 may have a different calibration or OS. The black box flash currently does a checksum to verify the contents. If the OS or calibration are different lengths or in different positions, it will flash fine as it does the whole thing (all 512 kB of it!), but "fail" the verification as the data is in different positons. Try downloading the whole bin that's on there now and compare it to what you got originally. If they're the same than it worked.
Its also possible that it has a failed bin to begin with. If they match, can you send me your bin (either attach, or PM me for email)? If it is different, then the bin check will have to actually read back the bin and verify to what was loaded vs. whats on the chip. Slower, but will work for other OS's that are different, but still work on the same hardware platform.

Re: Houston, we have reflash... PCM reflash tool
Some of these are real cheap on ebay. I dont think I can pass up $49

Re: Houston, we have reflash... PCM reflash tool
Read the PCM and compared to original and they are identical. So looks good for write although verify did not work.
Attached the original bin file read.
One thing noticed on read file is there is no VIN in calibration info? All other calibration Information is there, just XXXXXXXXXX for the VIN. Not sure if this PCM was like that before the read and flash? Was just a PCM laying here in a stack so I'm not sure what was on it or if something happened to VIN. Or how to fix VIN?
One user interface change that would help is for console to scroll to bottom so you know what is happening without having to scroll down or chase it.

Re: Houston, we have reflash... PCM reflash tool
I had a look. As I suspected the 99's have a different OS (hmm, wonder what changed?). Since the flash data is already verified during flashing and a calibration flash failure can always be recovered from, I took the verify bin out. In its place, in the "File" I have a exit flash mode, which exits the flash mode, and then checks to be sure no errors were set. If a flash error is present, a pop-up comes up indicating that a reflash is needed. In that case you just go back in and reflash. This is faster than waiting for the blue bar to snake its way across the screen while it cross-checks everything. Otherwise it indicates the PCM was reset and your good to go.
For the rare occasion you want to do the OS, you can DL the bin afterwards and compare with a hex editor before exiting flash mode. Probably a fair assumption that if your dinking with the OS, you probably have a hex editor as well
Anyhow, once its all in there I'll put up ver 0.4 with the auto scroll to end.

Re: Houston, we have reflash... PCM reflash tool
Cool! 
I've run into OS changes several times, but it's normally the PCM from 5.7L to 7.4L or vise versa. Good that this flash tool can do it because EFI Live can't!
What about the VIN?
I only have one more PCM and it's my original from my truck with an EFI License on it so don't want to mess it up? Plus with this project I may put it back and work on the XDF... Guess if I loose the VIN I can always put it back with TunerCat...
Shouldn't the Flash Tool write or change VIN like TC?

Re: Houston, we have reflash... PCM reflash tool
SO how many OS have you found for the 98-00 Black Box? All the other software titles it as such...
Is there a preferred OS that would cover the 5.7 and 7.4... was there a 5.0? If there's a bunch it would complicate the XDF process...
I think I still have the ADX you started and I tested in vehicle. With all the progress made recently in OBDII adx files it should be easy to make one worthy of tuning with.

Theoretically the flash tool should be able to put the BIN back exactly like it was before since it mirrors the entire thing. As for editing it and then flashing, that may be risky as EFI could lock you out.

Re: Houston, we have reflash... PCM reflash tool
Honestly I dont know, but Id guess there are several for the 99-00 span. On my PCM I took the 98 OS and put my own custom fueling code in it to get rid of the feed forward transient fueling they have, as well as add acceleration enrichment for my aluminum manifold. It also has n-alpha transient fueling for the 1000 CFM TB so it doesn't bog out when I hit the gas. Basically Im tied to this one OS since its purpose built for my car, so I haven't tried any others.

Re: Houston, we have reflash... PCM reflash tool
This tool just writes the BIN verbatim to the flash. Everything including dead space. Tuner Cats just does the cal sections and skips the dead space. No comment on HP as I've never seen their stuff. One advantage to this way is that it makes it universal. If the flash tool can start and run on the PCM, it can flash it. The OS always starts at 0x20000 on the PCMs, so thats the break point for the flash cal vs. flash OS.
I know how to find the VIN is in hex, I'm just wondering if it was missing or if there is a possibility of the Black Box Flash X'ed it out? Your VIN still there?
Haven't even had time to look at the bin in hex to see what happened, maybe I'll take the other PCM and read in TC to make sure it's there with a safe copy, then try again, see if it disappears? Like I said this was an unknown PCM, I should have done a read before testing the Black Box Flash, right now I don't know if this is an issue with the new flash or the issue was there...
The different OS will pose some challenges to the XDF. If it is anything like the LS1 XDF you made for OS 12202088 I found most everything for OS 12212156 almost identical just a few lines off. There's a few things I've left out do to them handled differently.
Anything else I can do to help?
And from everyone...

Re: Houston, we have reflash... PCM reflash tool
So it really does not matter as to what OS the Black Box PCM has, it will do the cal section or the full flash.

As for the flash, yeah, it doesn't really matter so long as the hardware is the same. It wont alter the VIN or any contents, so I suspect it was changed to a string of ASCII hex for the letter 'X' at some point previously.
Also Im going to finish automating the connection recovery logic in it. Right now it will re-establish the link and continue to flash the PCM if it looses and regains the connection (eg you pull the cable out from the port, and plug it back in again). The DL and other logic doesn't have that yet, so there is the possibility of it quitting in the middle of an instruction if the connection drops for a few seconds.

Re: Houston, we have reflash... PCM reflash tool
Ok, new version is up. Added autoscroll, fixed a few things that caused the UI to hang, and updated the security entry routine. Also added a help window with a quick start guide.
Eagle, I got to the bottom of the issue with the time-outs when it tried to start flash mode. The PCM has an error in the code. The frame for security time-out should be 6C F0 10 27 02 37 (Mode 27 security time delay not expired), but instead its 6C F0 10 27 01 37. The frame for sending a seed is 6C F0 10 27 01 [Seed], so if your PCM has a security seed that starts with 37, the code cannot tell whether its a seed frame with a missing byte or a time-out. I set it to assume the latter in that its a time out. If you still get that same error, there's a check box in advanced mode that will force a security entry, but try it normally first to see if it works.

Re: Houston, we have reflash... PCM reflash tool
If it does it after one minute, then you have one of the PCMs that has the above issue. The code cant differentiate the two because of it. Getting around the logic flaw from GM would mean complicating things a bit... Easy way is to just check the box if your PCM does that. My seed starts with 0x43, so it goes in after the delay.

Re: Houston, we have reflash... PCM reflash tool
Also had to upload a new version of the code. Fixing things evidently brings up new bugs that I couldn't see before. Only way to find these is to try to break things (pull out the cable, click all the buttons, intentionally corrupt the flash and crash the PCM, etc.)
At this rate I'll have to add automatic updates like windows!
At least its a few less bugs that are still left in it...

Re: Houston, we have reflash... PCM reflash tool
If that's the last update for today? I'll run read and write tests again tonight.
Not as daring as you to pull cable... but anything else you'd like?

Re: Houston, we have reflash... PCM reflash tool
Yeah, I wouldn't pull the cable on one without a socket. My bench PCM has a removable flash chip in case it pukes. Also pulling the cable removes power from the AVT, and can cause it to crash.
I made one more minor change to improve how it recovers from a faulty flash. Something you never want to see, but might happen. Thats probably all the updates I'll do for now. If you find anything else, let me know

Re: Houston, we have reflash... PCM reflash tool
You can double check if this is the case by going to advanced mode and typing the following command string into the "Send Command" window: 6C 10 F0 27 01. That will return the seed, which will be the last two bytes of the frame it gives you. The frame will be 6C F0 10 27 01 XX XX. If the first byte of the seed is 37, then it will confirm why it doesn't enter automatically.

Re: Houston, we have reflash... PCM reflash tool
Well here's a small glitch for now.
Opened the Black Box Flash and clicked Comm port and it was blank? D'oh! My cable was not plugged in, so I plugged it in and hit Refresh and still nothing?
Closed program and re-opened and it was there.
So in this case refresh did not work... no biggie, just FYI...

Re: Houston, we have reflash... PCM reflash tool
Flash was also fine, did need to use advanced and force again.
