Summary of change:
I received and ECU from a working car (no suspected problems with ECU) and the owner wanted help upgrading the firmware before putting the car on my dyno. Several things going on here : * The firmware upgrade simply aborted ** Even tried megaloader from MegaTune era ** As if it times out * Can't force the ECU to boot/safe mode by shorting rx/tx ** VT connects normally after a few seconds more than usual * Serial nr 1715, so old - but not very old. ** '''Shown full serial nr, will try to update ancient bootloader with main.hex file.''' What could be going on? Here is the firmware info and error message. http://www.vems.hu/files/MembersPage/MattiasSandgren/firmware-bootloader/fw-info.PNG http://www.vems.hu/files/MembersPage/MattiasSandgren/firmware-bootloader/fw-upload-wrong.PNG
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
