Ok, i tried reproducing the serial loopback in terminal to get AVREF11 and it wouldn't show back up again. Now all i get is just the <0> under regular serial connection. I know i may have dug myself a hole that I'm having problems getting out of, but with your help i should be able to fix it...either that or i'm buying a V3.3 board haha.
- I tried uploading the firmware with and without the "t" option but it yielded the same result ever time (note 'no AVR' picture below)
- I should note that I tried uploading firmware to it a long time ago using the AVR program.

Alright, thank you very much, the serial loopback got me back where i was. I removed the t from the -wtE on the upload-firmware12x12.bat file. Now I'm left with this.
Try ECU serial loopback
- power down
- connect ECU rs232 DSUB9pin2 to DSUB9pin3
- powerup
- TerminalProgram 19200,8n1 say "S" => expect AVREFI1
- now you can upload program with the upload_firmware.bat IF YOU REMOVE THE 't' from the megaloader vems.hex .... Etw command (so Etw becomes Ew, or if it's like "-w -t", than drop the "-t" ) since you are already in bootloader. You'll need the "t" later when you want to reflash normally (firmware running, not in bootloader mode)
- or you can try the experimental v3gui (download from MegaTune page).
This is where my car sits right now, I'm down to some of the last few details for getting it running and one of those hangups is my VEMS V3.2. I've had the controller for a while but have just recently been needing to use it.
My coil pack setup, my only fear with this setup is finding a way to get rotary trailing split to work.
