Ok guy's,

Here is the latest attempt to use the Ecuflash program to obtain an image of my ecu.
I have a Cobb Stg 2 AP flash. Attached is the error that I received.
I'm using Cobbs cable with a Belden serial to USB converter.
Any help?

[0.000] kernel flash disable
[3.045] denso02_bootloader_cmd_start
[0.020] 1452 byte kernel read.
[0.000] kernel checksum is valid (n = 2).
[0.200] writing denso kernel area addr: 020000 len: 05AC

[0.200] writing denso kernel area addr: 020000 len: 05AC

btw, everything is hooked up appropriately, green test connector and I tried w and w/o the flash block.
Thanks

Most USB to serial cables will not work because the don't support atypical baud rates, such as the 39373 baud needed by the OpenECU kernel. You need to have a FTDI USB to serial chipset or one that can perform similarly. Or get an OpenPort.

Is that chipset something that is part of the USB convertor cable?
The Belkin cable is a fairly high quality item.

Edit: Specs say only 115kbps

Yes, the chipset of the adapter. It's not a quality issue - it's one of functionality. Most USB-serial chipsets/drivers do not support anything other than the standard baud rates (e.g. 300, 1200, 2400, 4800, 9600, 14400, 19200, 38400, 57600, 115200).

i get the same errors when i try to connect, but i'm not using usb. i'm using just the cobb cable attached directly to the db9 comm port on the pc. maybe it has to do with the baud settings in windows for the comm port. does either ecuExplorer or ecuFlash set the baud rate or do they fetch the windows setting? what hardware/software are you guys using successfully?

This will not work. Your PC serial port does not support 39373 baud. Let me break it down here - there are only 2 working combinations:

1) Openport cable.
2) Cobb + FTDI based USB adapter.
