I removed the t from the -wtE on the upload-firmware12x12.bat file. Now I'm left with this. http://myweb.cableone.net/mjbless/vems1.jpg ---- 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. http://myweb.cableone.net/mjbless/project/2.jpg http://myweb.cableone.net/mjbless/project/4.jpg http://myweb.cableone.net/mjbless/project/5.jpg My coil pack setup, my only fear with this setup is finding a way to get rotary trailing split to work. http://myweb.cableone.net/mjbless/project/11.jpg Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
