Seems like 2 (possibly independent) issues, best noted on separate pages, please update the relevant page.
- MembersPage/WolfTm/WidebandIssueAfterUpgrade
- Note: happened after old VEMS ECU was replaced with new (also new fw ?), and never happened in 2500 kms with the old board. So might be related to:
- MembersPage/WolfTm/LeanAfterFwUpgrade
OLD, solved
- Support for ecu serial #10267
- A customer's V3.6 ecu suddendly lost serial number, seems to be in a kind of limp mode (10° and 0.65 lambda at any load/rpm).
- VemsTune is now displaying that Serial is unknown-0.
Granting (by info sent in priv),
Do you have ISP cable (Parport DSUB25 or USB-ISP ?) Will need to follow
http://vems.hu/vt/help/v3/general/bootloader_upgrade.html
If considering bootloader upgrade, (so that internal BOD can be disabled) highly recommended:
PLEASE CHECK THAT v3/10267 has reset chip at the atmega128/pin20 reset, eg
- mcp121 or mcp131 (U26 position)
- or mcp809 or max809 (U10 position)'''
See GenBoard/VerThree/Schematic eg
