PowerPCM_Flasher: my tool for E38 and E67

[ironduke]

Sorry, I know your looking for feedback from others, lol..

Depending on what OS you have with yours, you may want to set this up to be able to write the OS and calibration so you can upgrade/run a different OS if needed..

It has been working good for me as long as I'm wired, there is an issue with elm327, unhandled exemption.. Don't need it, but I tried it just because I wanted to..

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Any feedback from anyone is very welcome.

Thanks.


Ill check that ELM issue, im working on it anyways

[ironduke]

Forgot to mention.. I have my elm on com2.. If I leave it on com1 I don't get the error.. It happens as soon as I select com2 or com3, or com4..
If it's easy enough a LOT of people have used up the first 4 com ports.. I had to clear up some old no longer being used to make some room.. lol..

[daniel2345]

Ok, found your Error.

Will be fixed in next Version. You can leave the Dropdown Box as it is and enter any "COMxx" you want in the box text field.
For connect the prog will read the string and tries to connect with the extracted Number.


I made some progress with PassThru, changed the flow control from my prog to the used PassThru Device.
With that i was able to use the Volvo Dice without any "Hacks" in ISO15765 mode.
So i dropped Dice native mode and integrated it in PassThru.

Not very relevant for you as users, but only one PassThru Lib has to be maintained now.
Less work for Bugfixing and enhancements.

Relevant may be that readout time is now 100s (instead 120s before), flash time is only 1..2s faster.


On Elm327 side i also made some progress. Finally it sends my flashloader to the E38, but it is still buggy.
Sometimes those stupid ">?" answers instead of something useful is in the buffers.
I stopped for today before hitting the keyboard with my head
But I will find out and get it working.

Hate it, when machines dont do what they are supposed to do: obey my will

I would like to test the elm part but don`t have a pcm. If you add some test mode, I can test sending messages and logging them with another tool. At least you will know that sending works.

I suppose you are using an elm device with stn chip. If it is, you can use some extended command set not available for the average user.

[daniel2345]

Thanks for your offer.

Will add a testmode then.
Currently im stuck with the Elm327 just not sending long messages.
Don't know why, need to gather some motivation for it


Honestly i don't know what is inside the Cable. I bought it 15 Years ago - probably no STN Chip...

[kur4o]

If it is not stn than your stuck with 11 bytes max 20 bytes buffer.

Stn can send and receive upto 3k with the extended command set and 192 bytes with standard command set.

[MudDuck514]

Hi all;

Daniel,
PCMHammer will tell you if it has an STN chip inside - if not it will NOT connect!

[antus]

Yep the original elm chipset is not capable. Stn cant always do 3k, it depends which model. They have different amounts of ram and buffer size.

Couple questions. Any possible support for the e78 yet? I'm having a hell of a time finding things besides hpt and efilive that support it. Also, I have all sorts of cables and connectors. For j2534 and uds, is part of the secret to communicating with them changing up the baud and stuff like that? For instance I know with a serial device I can read the ecu via 27 (I know my particular key) with a baud of 11520 to the serial device and 500000 from device to CAN. What settings and/or hardware do I need to talk via passthru? Changing flow control and baud rate? Parity? Links to any good juicy info would be sweet. I feel like I've read everything about this stuff ok the web over the last year or so, and perhaps I'm stuck in a rut and cannot find other things to read. Haha.

One more question how are you guys finding out what works to determine the seed/key algos? I mean, I have at least a dozen tools with dlls that are named like they do this (seedkey.dll etc), but I am unsure of 1) how to use a dll in a programmatic way (I'm and engineer but never mess around with any Microsoft stuff) and 2) how would I essentially watch how it communicates with its software when being used. I looked a little into using python 3 ctypes as it may fit the bill but I just haven't really dug into it yet. Thanks
