Summary of change:
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 [http://www.vems.hu/files/genboardv3/v3.8/genboardv3.8_sch.pdf v3.8.pdf] ---- MembersPage/WolfTm/InputPullupAndEgtAmplifier * '''Support required for VEMS EGT amplifier'''
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.
